Certain interfaces are optional, however others are mandatory. This guide should reflect the changes in the XML project and keep track of the versions. Hopwfully this can remain simple! + +\section{Root} + +The XML root must be \texttt{<BrowserEvalProjectDocument>}. This should be sufficiently identifiable in both itself and in the JavaScript decoding as it will create an object called the root name. + +There must also be a \texttt{<version>} tag which has the attribute \texttt{id} containing a numerical representation of the version. Currently everything in this document can be assumed to be version 1. If future updates or corrections are made post delivery this should give the flexibility to ensure past projects still work. + +The root will also contain the following tags: setup and tracks. + +\section{Setup tag} + +The setup tag specifies certain global test settings including: the interface type to use, the project return location and any other setup instructions. +Any general pre/post test questions must be specified in the relevant children tag. Any enabled metrics must also be specified in the metric child node. + +\subsection{Attributes} +\begin{itemize} +\item \texttt{interface} - Mandatory, String. Defaults to APE, otherwise use to load any of the available interfaces. Currently only valid string is APE. +\item \texttt{projectReturn} - Mandatory, String. Specify the URL to return the test results. If null client will generate XML locally and prompt user to return the file. +\item \texttt{randomiseOrder} - Optional, default to false. Specify if the order of the tests can be randomised. +\item \texttt{collectMetrics} - Optional, Boolean. Default to false. Determine if the test metrics should be collected. These include how long each test session took etc. The full metrics list can be modified in the 'metrics' tag. +\end{itemize} + +\subsection{Elements} +None + +\section{AudioHolder tag} + +There should be one audioHolder tag per test session, inside which each audioElement is specified as children. The audioHolder tag can help to generalise certain objects. Each audioHolder instance specifies a separate listening test to be paged, each with their own specific requirements. + +\subsection{Attributes} +\begin{itemize} +\item \texttt{id} - Mandatory, String. Give an ID string or number to identify the test in the result. +\item \texttt{hostURL} - Optional, String. If all tracks are hosted from the same folder on a server, you can put in the lead here. For instance, if loading http://test.com/tracks/track1.wav and http://test.com/tracks/track2.wav, this could equal http://test.com/tracks/ and the url attribute in the track tag can be track1.wav or track2.wav. Equally http://test.com/ and then using tracks/track1.wav and tracks/track2.wav is valid. +\item \texttt{sampleRate} - Optional, Number. If your test requires a specific sample rate, this should be set to the desired sample rate in Hertz. This does not set the browser to the correct sample rate, but forces the browser to check the sample rate matches. If this is undefined, no sample rate matching will occur. +\item \texttt{randomiseOrder} - Optional, Boolean String. Defaults to false. Determine if the track order should be randomised. Must be true or false. +\item \texttt{repeatCount} - Optional, Number. Defaults to 0 (ie: no repeats). The number of times a test should be repeated. +\item \texttt{loop} - Optional, Boolean String. Defaults to false. Enable if audioElements should loop their playback or not. +\end{itemize} + +\subsection{Elements} +Contain the audioElements tags and the interfaceSetup tag. + +\section{audioElements tag} + +This must reside as children in the audioHolder tag. There must be one audioElement tag per sound sample to load into the test. + +\subsection{Attributes} +\begin{itemize} +\item \texttt{id} - Mandatory, String. Must give a string or number to identify each audio element. This id is used in the output to identify each track once randomised. +\item \texttt{url} - Mandatory, String. Contain the full URL to the track. If the Tracks tag hostURL is set, concatenate this tag with the hostURL attribute to obtain the full URL. +\end{itemize} + +\section{interface tag} + +This is contained within the audioHolder tag and outlines test instance specific requirements. These include the following children tags: +\begin{itemize} +\item 'title' - Contains the test title to be shown at the top of the page. Can only be one title node per interface. +\item 'scale' - Takes the attribute position to be a value between 0 and 100 indicating where on the scale to place the text contained inside. Can be multiple scale tags per interface. +\end{itemize} + +\section {CommentQuestion tag} + +This is a 1st level tag (same level as AudioHolder and setup). This allows another question and comment box to be presented on the page. The results of these are passed back in the results XML with both the comment and the question. The id attribute is set to keep track at the results XML. + +\section {PreTest tag and PostTest tag} + +These are 1st level tags. The PreTest tag allows for the specifying of pre test instructions and questions. These appear as a pop-up style window with next buttons and other automatic GUI. The postTest tag allows for specifying post test instructions, questions and resources. These appear as a pop-up style window after the submit button is pressed. + +\subsection{Attributes} +None. + +\subsection{Elements} +Takes the \texttt{statement} and \texttt{question} tags. The order these are presented in the XML define the order they appear on the screen. + +\subsubsection{Statement} + +The statement tag simply prints the included string verbatim on a 'pop-up' window with a next button. + +\subsubsection{Question} + +This allows for a question to be asked pre/post the test. This is added to the response XML in the same location as the other common/global questions. The response includes both the question asked and the response. This takes two attributes, id and mandatory. ID is a mandatory field. The same ID will be used in the results so it is important it is properly entered. Mandatory is optional. True means the field must be entered before continuing. + +\subsubsection{Resource} + +The resource tag is only available in the postTest tag. This allows for the linking to some external resource via the href attribute. + +\section{Metric tag} +A 1st level tag, metrics must be declared in the setup tag. This takes a set of children 'metricEnable' to define which metrics to collect and present. + +\subsection{metricEnable tag} +This takes a single attribute to determine which metric to enable for collection. Some of these are a global, per track or per test instance. +\begin{itemize} +\item testTimer - Return the global test timer and test instance timers. Measures the time between the first start and final submit. +\item elementTimer - Return the total time each audioElement in each test was listened too.

Corrected minor bug for improperly formed warning message when a +% book was not given a title. Thanks to Ming Kin Lai for reporting this. +% 2. Added support for CTLname_format_string and CTLname_latex_cmd fields +% in the BST control entry type. +% +% 1.11 (2003/04/02) +% 1. Fixed bug with URLs containing underscores when using url.sty. Thanks +% to Ming Kin Lai for reporting this. +% +% 1.12 (2007/01/11) +% 1. Fixed bug with unwanted comma before "et al." when an entry contained +% more than two author names. Thanks to Pallav Gupta for reporting this. +% 2. Fixed bug with anomalous closing quote in tech reports that have a +% type, but without a number or address. Thanks to Mehrdad Mirreza for +% reporting this. +% 3. Use braces in \providecommand in begin.bib to better support +% latex2html. TeX style length assignments OK with recent versions +% of latex2html - 1.71 (2002/2/1) or later is strongly recommended. +% Use of the language field still causes trouble with latex2html. +% Thanks to Federico Beffa for reporting this. +% 4. Added IEEEtran.bst ID and version comment string to .bbl output. +% 5. Provide a \BIBdecl hook that allows the user to execute commands +% just prior to the first entry. +% 6. Use default urlstyle (is using url.sty) of "same" rather than rm to +% better work with a wider variety of bibliography styles. +% 7. Changed month abbreviations from Sept., July and June to Sep., Jul., +% and Jun., respectively, as IEEE now does. Thanks to Moritz Borgmann +% for reporting this. +% 8. Control entry types should not be considered when calculating longest +% label width. +% 9. Added alias www for electronic/online. +% 10. Added CTLname_url_prefix control entry type. + + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +%% DEFAULTS FOR THE CONTROLS OF THE BST STYLE %% +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% + +% These are the defaults for the user adjustable controls.

(Note: IEEEtran.bst does not need +% or use the newline/newblock feature, but it has been implemented for +% possible future use.) The output states of IEEEtran.bst consist of +% multiple independent attributes and, as such, can be thought of as being +% vectors, rather than the simple scalar values ("before.all", +% "mid.sentence", etc.) used in most other .bst files. +% +% The more flexible and complex design used here was motivated in part by +% IEEE's rather unusual bibliography style. For example, IEEE ends the +% previous field item with a period and large space prior to the publisher +% address; the @electronic entry types use periods as inter-item punctuation +% rather than the commas used by the other entry types; and URLs are never +% followed by periods even though they are the last item in the entry. +% Although it is possible to accommodate these features with the conventional +% output state system, the seemingly endless exceptions make for convoluted, +% unreliable and difficult to maintain code. +% +% IEEEtran.bst's output state system can be easily understood via a simple +% illustration of two most recently formatted entry fields (on the stack): +% +% CURRENT_ITEM +% "PREVIOUS_ITEM +% +% which, in this example, is to eventually appear in the bibliography as: +% +% "PREVIOUS_ITEM," CURRENT_ITEM +% +% It is the job of the output routine to take the previous item off of the +% stack (while leaving the current item at the top of the stack), apply its +% trailing punctuation (including closing quote marks) and spacing, and then +% to write the result to BibTeX's output buffer: +% +% "PREVIOUS_ITEM," +% +% Punctuation (and spacing) between items is often determined by both of the +% items rather than just the first one. The presence of quotation marks +% further complicates the situation because, in standard English, trailing +% punctuation marks are supposed to be contained within the quotes. +% +% IEEEtran.bst maintains two output state (aka "status") vectors which +% correspond to the previous and current (aka "this") items. Each vector +% consists of several independent attributes which track punctuation, +% spacing, quotation, and newlines. Capitalization status is handled by a +% separate scalar because the format routines, not the output routine, +% handle capitalization and, therefore, there is no need to maintain the +% capitalization attribute for both the "previous" and "this" items. +% +% When a format routine adds a new item, it copies the current output status +% vector to the previous output status vector and (usually) resets the +% current (this) output status vector to a "standard status" vector. Using a +% "standard status" vector in this way allows us to redefine what we mean by +% "standard status" at the start of each entry handler and reuse the same +% format routines under the various inter-item separation schemes. For +% example, the standard status vector for the @book entry type may use +% commas for item separators, while the @electronic type may use periods, +% yet both entry handlers exploit many of the exact same format routines. +% +% Because format routines have write access to the output status vector of +% the previous item, they can override the punctuation choices of the +% previous format routine! Therefore, it becomes trivial to implement rules +% such as "Always use a period and a large space before the publisher." By +% pushing the generation of the closing quote mark to the output routine, we +% avoid all the problems caused by having to close a quote before having all +% the information required to determine what the punctuation should be. +% +% The IEEEtran.bst output state system can easily be expanded if needed. +% For instance, it is easy to add a "space.tie" attribute value if the +% bibliography rules mandate that two items have to be joined with an +% unbreakable space. + +FUNCTION {initialize.status.constants} +{ #0 'punct.no := + #1 'punct.comma := + #2 'punct.period := + #0 'space.no := + #1 'space.normal := + #2 'space.large := + #0 'quote.no := + #1 'quote.close := + #0 'cap.no := + #1 'cap.yes := + #0 'nline.no := + #1 'nline.newblock := +} + +FUNCTION {std.status.using.comma} +{ punct.comma 'punct.std := + space.normal 'space.std := + quote.no 'quote.std := + nline.no 'nline.std := + cap.no 'cap.std := +} + +FUNCTION {std.status.using.period} +{ punct.period 'punct.std := + space.normal 'space.std := + quote.no 'quote.std := + nline.no 'nline.std := + cap.yes 'cap.std := +} + +FUNCTION {initialize.prev.this.status} +{ punct.no 'prev.status.punct := + space.no 'prev.status.space := + quote.no 'prev.status.quote := + nline.no 'prev.status.nline := + punct.no 'this.status.punct := + space.no 'this.status.space := + quote.no 'this.status.quote := + nline.no 'this.status.nline := + cap.yes 'status.cap := +} + +FUNCTION {this.status.std} +{ punct.std 'this.status.punct := + space.std 'this.status.space := + quote.std 'this.status.quote := + nline.std 'this.status.nline := +} + +FUNCTION {cap.status.std}{ cap.std 'status.cap := } + +FUNCTION {this.to.prev.status} +{ this.status.punct 'prev.status.punct := + this.status.space 'prev.status.space := + this.status.quote 'prev.status.quote := + this.status.nline 'prev.status.nline := +} + + +FUNCTION {not} +{ { #0 } + { #1 } + if$ +} + +FUNCTION {and} +{ { skip$ } + { pop$ #0 } + if$ +} + +FUNCTION {or} +{ { pop$ #1 } + { skip$ } + if$ +} + + +% convert the strings "yes" or "no" to #1 or #0 respectively +FUNCTION {yes.no.to.int} +{ "l" change.case$ duplicate$ + "yes" = + { pop$ #1 } + { duplicate$ "no" = + { pop$ #0 } + { "unknown boolean " quote$ * swap$ * quote$ * + " in " * cite$ * warning$ + #0 + } + if$ + } + if$ +} + + +% pushes true if the single char string on the stack is in the +% range of "0" to "9" +FUNCTION {is.num} +{ chr.to.int$ + duplicate$ "0" chr.to.int$ < not + swap$ "9" chr.to.int$ > not and +} + +% multiplies the integer on the stack by a factor of 10 +FUNCTION {bump.int.mag} +{ #0 'multiresult := + { duplicate$ #0 > } + { #1 - + multiresult #10 + + 'multiresult := + } + while$ +pop$ +multiresult +} + +% converts a single character string on the stack to an integer +FUNCTION {char.to.integer} +{ duplicate$ + is.num + { chr.to.int$ "0" chr.to.int$ - } + {"noninteger character " quote$ * swap$ * quote$ * + " in integer field of " * cite$ * warning$ + #0 + } + if$ +} + +% converts a string on the stack to an integer +FUNCTION {string.to.integer} +{ duplicate$ text.length$ 'namesleft := + #1 'nameptr := + #0 'numnames := + { nameptr namesleft > not } + { duplicate$ nameptr #1 substring$ + char.to.integer numnames bump.int.mag + + 'numnames := + nameptr #1 + + 'nameptr := + } + while$ +pop$ +numnames +} + + + + +% The output routines write out the *next* to the top (previous) item on the +% stack, adding punctuation and such as needed.

These require specialised software, usually custom-made, to collect large amounts of data using meticulously designed interfaces with carefully formulated questions, and play back audio with rapid switching between different samples. +New functionality in HTML5 included in the Web Audio API allows for increasingly powerful media applications in a platform independent environment. The advantage of a web application is easy deployment on any platform, without requiring any other application, enabling multiple tests to be easily conducted across locations. In this paper we propose a tool supporting a wide variety of easily configurable, multi-stimulus perceptual audio evaluation tests over the web with multiple test interfaces, pre- and post-test surveys, custom configuration, collection of test metrics and other features. Test design and setup doesn't require programming background, and results are gathered automatically using web friendly formats for easy storing of results on a server. +% Currently at 150, don't think anything more needs to be done here?? +%Place your abstract at the top left column on the first page. +%Please write about 150-200 words that specifically highlight the purpose of your work, +%its context, and provide a brief synopsis of your results. +%Avoid equations in this part.\\ + +\end{abstract} + +% TOTAL PAPER: Minimum 4 pages, 6 preferred, max. 8 (6 for demos/posters)\\ + +\section{Introduction}\label{sec:introduction} + +%NICK: examples of what kind of audio applications HTML5 has made possible, with references to publications (or website)\\ + +Perceptual evaluation of audio plays an important role in a wide range of research on audio quality \cite{schoeffler2013impact,repp}, sound synthesis \cite{de2013real,durr2015implementation}, audio effect design \cite{deman2014a}, source separation \cite{mushram,uhlereiss}, music and emotion analysis \cite{song2013a,eerola2009prediction}, and many others \cite{friberg2011comparison}. % codec design? + +%This work is based in part on the APE audio perceptual evaluation interface for MATLAB \cite{deman2014b}. An important drawback of this toolbox is the need to have MATLAB to create a test and even to run (barring the use of an executable generated by MATLAB), and limited compatibility with both earlier and newer versions of MATLAB, which makes it hard to maintain. On the other hand, a web application generally has the advantage of running in most browsers on most applications. + +% IMPORTANT +%[TO ADD: other interfaces for perceptual evaluation of audio, browser-based or not!] \\ +%BROWSER-BASED: \cite{song2013b,song2013a,beaqlejs} \\ +%MATLAB: \cite{whisper,mushram,scale} +% to add: OPAQUE, Rumsey's repertory grid technique + + +\begin{table}[htdp] +\caption{Available audio perceptual evaluation tools} +\begin{center} +\begin{tabular}{|*{3}{l|}} +% order? +\hline +\textbf{Name} & \textbf{Language} & \textbf{Ref.}\\ +\hline +APE & MATLAB & \cite{deman2014b} \\ +BeaqleJS & HTML5/JS & \cite{beaqlejs}\\ % ABX, mushra +%C4DM\footnote{http://isophonics.org/test - collection of listening tests developed by Gy\"{o}rgy Fazekas and Thomas Wilmering at Centre for Digital Music.} & JS & \cite{song2013a,song2013b}\\ +HULTI-GEN & Max & \cite{hulti-gen}\\ +MUSHRAM & MATLAB & \cite{mushram}\\ % type: mushra +Scale & MATLAB & \cite{scale} \\ +WhisPER & MATLAB & \cite{whisper}\\ +\hline +\end{tabular} +\end{center} +\label{tab:interfaces} +\end{table}% + +Various listening test design tools are already available, see Table \ref{tab:interfaces}. A few other listening test tools, such as OPAQUE \cite{opaque} and GuineaPig \cite{guineapig}, are described but not available to the public at the time of writing. + +Many are MATLAB-based, useful for easily processing and visualising the data produced by the listening tests, but requiring MATLAB to be installed to run or - in the case of an executable created with MATLAB - at least create the test. +Furthermore, compatibility is usually limited across different versions of MATLAB. +Similarly, Max requires little or no programming background but it is proprietary software as well, which is especially undesirable when tests need to be deployed at different sites. +More recently, BeaqleJS \cite{beaqlejs} makes use of the HTML5 audio capabilities and comes with a number of predefined, established test interfaces such as ABX and MUSHRA \cite{mushra}. % + +A browser-based perceptual evaluation tool for audio has a number of advantages. First of all, it doesn't need any other software than a browser, meaning deployment is very easy and cheap. As such, it can also run on a variety of devices and platforms. The test can be hosted on a central server with subjects all over the world, who can simply go to a webpage. This means that multiple participants can take the test simultaneously, potentially in their usual listening environment if this is beneficial for the test. Naturally, the constraints on the listening environment and other variables still need to be controlled if they are important to the experiment. Depending on the requirements a survey or a variety of tests preceding the experiment could establish whether remote participants and their environments are adequate for the experiment at hand. + +The Web Audio API is a high-level JavaScript Application Programming Interface (API) designed for real-time processing of audio inside the browser through various processing nodes\footnote{http://webaudio.github.io/web-audio-api/}. Various web sites have used the Web Audio API for creative purposes, such as drum machines and score creation tools\footnote{http://webaudio.github.io/demo-list/}, +others from the list show real-time captured audio processing such as room reverberation tools and a phase vocoder from the system microphone. The BBC Radiophonic Workshop shows effects used on famous TV shows such as Doctor Who, being simulated inside the browser\footnote{http://webaudio.prototyping.bbc.co.uk/}. +Another example is the BBC R\&D personalised compressor which applies a dynamic range compressor on a radio station that dynamically adjusts the compressor settings to match the listener's environment \cite{mason2015compression}. + + + +% [How is this one different from all these?] improve + +% FLEXIBLE (reference (not) appropriate) +In contrast with the tools listed above, we aim to provide an environment in which a variety of multi-stimulus tests can be designed, with a wide range of configurability, while keeping setup and collecting results as straightforward as possible. For instance, the option to provide free-text comment fields allows for tests with individual vocabulary methods, as opposed to only allowing quantitative scales associated to a fixed set of descriptors. +% EASE OF USE: no need to go in the code +To make the tool accessible to a wide range of researchers, we aim to offer maximum functionality even to those with little or no programming background. The tool we present can set up a listening test without reading or adjusting any code, provided no new types of interfaces need to be created. + +% ENVIRONMENT %In this paper, we provide a listening test back end that allows for easy set up of a wide variety of listening tests, highly flexible yet very simple and not requiring any programming skills. +Specifically, we present a browser-based perceptual evaluation tool from which any kind of multiple stimulus audio evaluation tool where subjects need to rank, rate, select, or comment on different audio samples can be built. +We also include an example of the multiple stimulus user interface included with the APE tool \cite{deman2014b}, which presents the subject with a number of axes on which a number of markers, corresponding to audio samples, can be moved to reflect any subjective quality, as well as corresponding comment boxes. +However, other graphical user interfaces can be put on top of the engine that we provide with minimal or no modifications. Examples of this are the MUSHRA test \cite{mushra}, single or multiple stimulus evaluation with a two-dimensional interface (such as valence and arousal dimensions), or simple annotation (using free-form text, check boxes, radio buttons or drop-down menus) of one or more audio samples at a time. +In some cases, such as method of adjustment, where the audio is processed by the user, or AB test, where the interface does not show all audio samples to be evaluated at once \cite{bech}, the back end of the tool needs to be modified as well. + +In the following sections, we describe the included interface in more detail, discuss the implementation, and cover considerations that were made in the design process of this tool. + +%\section{Requirements}\label{sec:requirements} +%??? +% +%\begin{itemize} +%\item +%\end{itemize} + + +\section{Interface}\label{sec:interface} + +At this point, we have implemented the interface of the MATLAB-based APE (Audio Perceptual Evaluation) toolbox \cite{deman2014b}. This shows one marker for each simultaneously evaluated audio fragment on one or more horizontal axes, that can be moved to rate or rank the respective fragments in terms of any subjective property, as well as a comment box for every marker, and any extra text boxes for extra comments. +The reason for such an interface, where all stimuli are presented on a single rating axis (or multiple axes if multiple subjective qualities need to be evaluated), is that it urges the subject to consider the rating and/or ranking of the stimuli relative to one another, as opposed to comparing each individual stimulus to a given reference, as is the case with e.g. a MUSHRA test \cite{mushra}. As such, it is ideal for any type of test where the goal is to carefully compare samples against each other, like perceptual evaluation of different mixes of music recordings \cite{deman2015a} or sound synthesis models \cite{durr2015implementation}, as opposed to comparing results of source separation algorithms \cite{mushram} or audio with lower data rate \cite{mushra} to a high quality reference signal. + +The markers on the slider at the top of the page are positioned randomly, to minimise the bias that may be introduced when the initial positions are near the beginning, end or middle of the slider. Another approach is to place the markers outside of the slider bar at first and have the subject drag them in, but the authors believe this doesn't encourage careful consideration and comparison of the different fragments as the implicit goal of the test becomes to audition and drag each fragment in just once, rather than to compare all fragments rigorously. + +See Figure \ref{fig:interface} for an example of the interface, with six fragments and one axis. %? change if a new interface is shown + +%Most of these functions are specific to the APE interface design, for instance the AB test will need a different structure for the audio engine and loading of files, since multiple instances of the same file are required. % more generally these pertain to any typeof multi-stimulus test - not quite useful for AB tests, method of adjustment, ABX, and so on. +%There are some areas of the design where certain design choices had to be made such as with the markers. + +%For instance, the option to provide free-text comment fields allows for tests with individual vocabulary methods, as opposed to only allowing quantitative scales associated to a fixed set of descriptors. + +\begin{figure*}[ht] +\begin{center} +\includegraphics[width=1.0\textwidth]{interface2.png} +\caption{Example of interface, with 1 axis, 6 fragments and 1 extra comment in Chrome browser} +\label{fig:interface} +\end{center} +\end{figure*} + + +\section{Architecture}\label{sec:architecture} % or implementation? + +The tool uses entirely client side processing utilising the new HTML5 Web Audio API, supported by most major web browsers. The API allows for constructing audio processing elements and connecting them together to produce a high quality, real time signal process to manipulate audio streams. The API supports multichannel processing and has an accurate playback timer for precise, scheduled playback control. The API is controlled through the browser JavaScript engine and is therefore highly configurable. Processing is all performed in a low latency thread separate from the main JavaScript thread, so there is no blocking due to real time processing. + +The web tool itself is split into several files to operate: +\begin{itemize} +\item \texttt{index.html}: The main index file to load the scripts, this is the file the browser must request to load. +\item \texttt{core.js}: Contains global functions and object prototypes to define the audio playback engine, audio objects and loading media files +\item \texttt{ape.js}: Parses setup files to create the interface as instructed, following the same style chain as the MATLAB APE Tool \cite{deman2014b}. +\end{itemize} + +The HTML file loads the \texttt{core.js} file along with a few other ancillary files (such as the jQuery JavaScript extensions\footnote{http://jquery.com/}), at which point the browser JavaScript begins to execute the on-page instructions, which gives the URL of the test setup XML document (outlined in Section \ref{sec:setupresultsformats}). \texttt{core.js} parses this document and executes the functions in \texttt{ape.js} to build the web page. The reason for separating these two files is to allow for further interface designs (such as MUSHRA \cite{mushra} or AB tests \cite{bech}) to be used, which would still require the same underlying core functions outlined in \texttt{core.js}. + +The \texttt{ape.js} file has several main functions but the most important are documented here. \textit{loadInterface(xmlDoc)} is called to decode the supplied project document in respect for the interface specified and define any global structures (such as the slider interface). It also identifies the number of pages in the test and randomises the order, if specified to do so. This is the only mandatory function in any of the interface files as this is called by \texttt{core.js} when the document is ready. \texttt{core.js} cannot 'see' any interface specific functions and therefore cannot assume any are available. Therefore \textit{loadInterface(xmlDoc)} is essential to set up the entire test environment. Because the interface files are loaded by \texttt{core.js} and because the functions in \texttt{core.js} are global, the interface files can `see' the \texttt{core.js} file and can therefore not only interact with it, but also modify it. + +Each test page is loaded using \textit{loadTest(id)} which performs two major tasks: to populate the interface with the slider elements and comment boxes; and secondly to instruct the \textit{audioEngine} to load the audio fragments and construct the backend audio graph. \textit{loadTest(id)} also instructs the audio engine in \texttt{core.js} to create the \textit{audioObject}. +These are custom audio nodes, one representing each audio element specified in each page. +They consist of a \textit{bufferSourceNode} (a node which holds a buffer of audio samples for playback) and a \textit{gainNode}, both of which are Web Audio API Nodes. Various functions are applied, depending on which metrics are enabled, to record the interaction with the audio element. These nodes are then connected to the \textit{audioEngine} (itself a custom web audio node) containing a \textit{gainNode} (where the various \textit{audioObject}s connect to) for summation before passing the output to the \textit{destinationNode}, a permanent node of the Web Audio API created as the master output. Here, the browser then passes the audio information to the system sound device. % Does this now make sense? +% audio object/audioObject/Audio Object: -- should always be audioObject if talking about the JavaScript object, otherwise should say audio element or audio fragment. + +When an \textit{audioObject} is created, it is given the URL of the audio sample to load. This is downloaded into the browser asynchronously using the \textit{XMLHttpRequest} object, which downloads any file into the JavaScript environment for further processing. This is particularly useful for the Web Audio API because it supports downloading of files in their binary form for decoding. Once downloaded the file is decoded using the Web Audio API offline decoder. This uses the browser available decoding schemes to decode the audio files into raw float32 arrays, which are in turn passed to the relevant \textit{audioObject} for playback. + +Once each page of the test is completed, identified by pressing the Submit button, the \textit{pageXMLSave(testId)} is called to store all of the collected data until all pages of the test are completed. After the final test and any post-test questions are completed, the \textit{interfaceXMLSave()} function is called. This function generates the final XML file for submission as outlined in Section \ref{sec:setupresultsformats}. + +\section{Support and limitations}\label{sec:support} + +Browsers support various audio file formats and are not consistent in any format. Currently the Web Audio API is best supported in Chrome, Firefox, Opera and Safari. All of these support the use of the uncompressed WAV format. Although not a compact, web friendly format, most transport systems are of a high enough bandwidth this should not be a problem. Ogg Vorbis is another well supported format across the four supported major desktop browsers, as well as MP3 (although Firefox may not support all MP3 types) \footnote{https://developer.mozilla.org/en-US/docs/Web/HTML/\\Supported\_media\_formats}. %https://developer.mozilla.org/en-US/docs/Web/HTML/Supported_media_formats +One issue of the Web Audio API is that the sample rate is assigned by the system sound device, rather than requested and does not have the ability to request a different one. % Does this make sense? The problem is across all audio files. +As the sampling rate and the effect of resampling may be critical for some listening tests, the default operation when an audio file is loaded with a different sample rate to that of the system is to convert the sample rate. To provide a check for this, the desired sample rate can be supplied with the setup XML and checked against. If the sample rates do not match, a browser alert window is shown asking for the sample rate to be correctly adjusted. +This happens before any loading or decoding of audio files so the browser will only be instructed to fetch files if the system sample rate meets the requirements, avoiding multiple requests for large files until they are actually needed. + +%During playback, the playback nodes loop indefinitely until playback is stopped. The gain nodes in the \textit{audioObject}s enable dynamic muting of nodes. When a bar in the sliding ranking is clicked, the audio engine mutes all \textit{audioObject}s and un-mutes the clicked one. Therefore, if the audio samples are perfectly aligned up and of the same sample length, they will remain perfectly aligned with each other. +% Don't think this is relevant anymore + + +\section{Input and result files}\label{sec:setupresultsformats} + +The setup and result files both use the common XML document format to outline the various parameters. The setup file determines the interface to use, the location of audio files, the number of pages and other parameters to define the testing environment. Having one document to modify allows for quick manipulation in a `human readable' form to create new tests, or adjust current ones, without needing to edit multiple web files. Furthermore, we also provide a simple web page to enter all these settings without needing to manipulate the raw XML. An example of this XML document is presented in Figure~\ref{fig:xmlIn}. % I mean the .js and .html files, though not sure if any better. + +\subsection{Setup and configurability} + +\begin{figure}[ht] +\begin{center} +\includegraphics[width=0.5\textwidth]{XMLInput2.png} +\caption{An example input XML file} +\label{fig:xmlIn} +\end{center} +\end{figure} + +The setup document has several defined nodes and structure which are documented with the source code. For example, there is a section for general setup options where any pre-test and post-test questions and statements can be defined. Pre- and post-test dialogue boxes allow for comments or questions to be presented before or after the test, to convey listening test instructions, and gather information about the subject, listening environment, and overall experience of the test. In the example in Figure~\ref{fig:xmlIn}, a question box with the id `location' is added, which is set to be mandatory to answer. The question is in the PreTest node meaning it will appear before any testing will begin. When the result for the entire test is shown, the response will appear in the PreTest node with the id `location' allowing it to be found easily, provided the id values are meaningful. + +We try to cater to a diverse audience with this toolbox, while ensuring it is simple, elegant and straightforward. To that end, we currently include the following options that can be easily switched on and off, by setting the value in the input XML file. + +\begin{itemize} %Should have used a description list for this. +\item \textbf{Snap to corresponding position}: When this is enabled, and a fragment is playing, the playhead skips to the same position in the next fragment that is clicked. If it is not enabled, every fragment is played from the start. +\item \textbf{Loop fragments}: Repeat current fragment when end is reached, until the `Stop audio' or `Submit' button is clicked. +\item \textbf{Comments}: Displays a separate comment box for each fragment in the page. +\item \textbf{General comment}: One comment box, additional to the individual comment boxes, to comment on the test or a feature that some or all of the fragments share. +\item \textbf{Resampling}: When this is enabled, tracks are resampled to match the subject's system's sample rate (a default feature of the Web Audio API). When it is not, an error is shown when the system does not match the requested sample rate. +\item \textbf{Randomise page order}: Randomises the order in which different `pages' are presented. % are we calling this 'pages'? +\item \textbf{Randomise fragment order}: Randomises the order and numbering of the markers and comment boxes corresponding to the fragments. This permutation is stored as well, to be able to interpret references to the numbers in the comments (such as `this is much [brighter] then 4'). +\item \textbf{Require playback}: Require that each fragment has been played at least once, if not in full. +\item \textbf{Require full playback}: If `Require playback' is active, require that each fragment has been played in full. +\item \textbf{Require moving}: Require that each marker is moved (dragged) at least once. +\item \textbf{Require comments}: This option allows requiring the subject to require a comment for each track. +\item \textbf{Repeat test}: Number of times each page in the test should be repeated (none by default), to allow familiarisation with the content and experiment, and to investigate consistency of user and variability due to familiarity. In the setup, each 'page' can be given a repeat count. These are all gathered before shuffling the order so repeated tests are not back-to-back if possible. +\item \textbf{Returning to previous pages}: Indicates whether it is possible to go back to a previous `page' in the test. +\item \textbf{Lowest rating below [value]}: To enforce a certain use of the rating scale, it can be required to rate at least one sample below a specified value. +\item \textbf{Highest rating above [value]}: To enforce a certain use of the rating scale, it can be required to rate at least one sample above a specified value. +\item \textbf{Reference}: Allows for a separate sample (outside of the axis) to be the `reference', which the subject can play back during the test to help with the task at hand \cite{mushra}. +\item \textbf{Hidden reference}: Whether or not an explicit `reference' is provided, the `hidden reference' should be rated above a certain value \cite{mushra} - this can be enforced. +\item \textbf{Hidden anchor}: The `hidden anchor' should be rated lower than a certain value \cite{mushra} - this can be enforced. +\item \textbf{Show scrub bar}: Display a playhead on a scrub bar to show the position in the current fragment. +\item \textbf{Drag playhead}: If scrub bar is visible, allow dragging to move back or forward in a fragment. +\end{itemize} + +When one of these options is not included in the setup file, they assume a default value. As a result, the input file can be kept very compact if default values suffice for the test. + +% loop, snap to corresponding position, comments, 'general' comment, require same sampling rate, different types of randomisation + +\subsection{Results} + +The results file is dynamically generated by the interface upon clicking the `Submit' button. This also executes checks, depending on the setup file, to ensure that all tracks have been played back, rated and commented on. The XML output returned contains a node per audioObject and contains both the corresponding marker's position and any comments written in the associated comment box. The rating returned is normalised to be a value between 0 and 1, normalising the pixel representation of different browser windows. An example output file is presented in Figure~\ref{fig:xmlOut}. + +\begin{figure}[ht] +\begin{center} +\includegraphics[width=0.5\textwidth]{XMLOutput2.png} +\caption{An example output XML file} +\label{fig:xmlOut} +\end{center} +\end{figure} + +The results also contain information collected by any defined pre/post questions. These are referenced against the setup XML by using the same ID so readable responses can be obtained. Taking from the earlier example of setting up a pre-test question, an example response can be seen in Figure \ref{fig:xmlOut}. + +Each page of testing is returned with the results of the entire page included in the structure. One `audioElement' node is created per audio fragment per page, along with its ID. This includes several child nodes including the rating between 0 and 1, the comment, and any other collected metrics including how long the element was listened for, the initial position, boolean flags if the element was listened to, if the element was moved and if the element comment box had any comment. Furthermore, each user action (manipulation of any interface element, such as playback or moving a marker) can be logged along with a the corresponding time code. +We also store session data such as the browser the tool was used in. +We provide the option to store the results locally, and/or to have them sent to a server. + +%Here is an example of the set up XML and the results XML: % perhaps best to refer to each XML after each section (set up <> results) +% Should we include an Example of the input and output XML structure?? --> Sure. + +%An example of the returned \textit{audioElement} node in the results XML file is as follows. +% +%\texttt{<audioelement id="8"> \\ +%<comment> \\ +%<question>Comment on track 0</question> \\ +%<response> The drums were punchy </response> \\ +%</comment> \\ +%<value> 0.25169491525423726 </value> \\ +%<metric> \\ +%<metricresult id="elementTimer"> \\ 2.3278004535147385< /metricresult> \\ +%<metricresult id="elementTrackerFull"> \\ +%<timepos id="0"> \\ +%<time>1.7937414965986385</time> \\ +%<position>0.41694915254237286</position> \\ +%</timepos> \\ +%<timepos id="1"> \\ +%<time>2.6993197278911563</time> \\ +%<position>0.45847457627118643</position> \\ +%</timepos> \\</metricresult> \\ +%<metricresult id="elementInitialPosition"> 0.47796610169491527 </metricresult> \\ +%<metricresult id="elementFlagListenedTo"> true< /metricresult> \\ +%<metricresult id="elementFlagMoved"> true </metricresult> \\ +%</metric> \\ +%</audioelement>} + +The parent tag \texttt{audioelement} holds the ID of the element passed in from the setup document. The first child element is \texttt{comment} and holds both the question shown and the response from the comment box inside. +The child element \texttt{value} holds the normalised ranking value. Next comes the metric node structure, with one metric result node per metric event collected. The id of the node identifies the type of data it contains. For example, the first holds the id \textit{elementTimer} and the data contained represents how long, in seconds, the audio element was listened to. There is one \texttt{audioelement} tag per audio element on each test page. + + +\section{Conclusions and future work}\label{sec:conclusions} + +In this paper we have presented an approach to creating a browser-based listening test environment that can be used for a variety of types of perceptual evaluation of audio. +Specifically, we discussed the use of the toolbox in the context of assessment of preference for different production practices, with identical source material. +The purpose of this paper is to outline the design of this tool, to describe our implementation using basic HTML5 functionality, and to discuss design challenges and limitations of our approach. This tool differentiates itself from other perceptual audio tools by enabling web technologies for multiple participants to perform the test without the need for proprietary software such as MATLAB. The tool also allows for any interface to be built using HTML5 elements to create a variety of dynamic, multiple-stimulus listening test interfaces. It enables quick setup of simple tests with the ability to manage complex tests through a single file. Finally it uses the XML document format to store the results allowing for processing and analysis of results in various third party software such as MATLAB or Python. + +% future work +Further work may include the development of other common test designs, such as MUSHRA \cite{mushra}, 2D valence and arousal/activity \cite{ratingeerola2009prediction}, and others. We will add functionality to assist with setting up large-scale tests with remote subjects, so this becomes straightforward and intuitive. +In addition, we will keep on improving and expanding the tool, and highly welcome feedback and contributions from the community. + +The source code of this tool can be found on \\ \texttt{code.soundsoftware.ac.uk/projects/}\\ \texttt{webaudioevaluationtool}. + + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +%bibliography here +\bibliography{smc2015template} + +\end{document}

For more information, see +// https://github.com/jrburke/requirejs/wiki/Updating-existing-libraries#wiki-anon + +if ( typeof define === "function" && define.amd ) { + define( "jquery", [], function() { + return jQuery; + }); +} + + + + +var + // Map over jQuery in case of overwrite + _jQuery = window.jQuery, + + // Map over the $ in case of overwrite + _$ = window.$; + +jQuery.noConflict = function( deep ) { + if ( window.$ === jQuery ) { + window.$ = _$; + } + + if ( deep && window.jQuery === jQuery ) { + window.jQuery = _jQuery; + } + + return jQuery; +}; + +// Expose jQuery and $ identifiers, even in AMD +// (#7102#comment:10, https://github.com/jquery/jquery/pull/557) +// and CommonJS for browser emulators (#13566) +if ( typeof noGlobal === strundefined ) { + window.jQuery = window.$ = jQuery; +} + + + + +return jQuery; + +}));
