+An XML file containing all project information to load and execute the project on the client. 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.
+
+An example of this tag could be:
+
+\texttt{<setup interface="APE" projectReturn="http://project.return.url/goes/here" />}
+
+The setup should not have any element or any children.
+
+\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.
+\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{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.
+\item \texttt{ID} - Optional, Number. Give the track a specific ID for the return. This will help if using multiple projects to spread a test across multiple sessions and/or locations, where each test will not use all the samples. If one audioElement is given the ID 3, the next audioElement (assuming it does not have an ID set itself) will have the ID of 4. This continues until the next audioElement with the ID attribute set is reached.
+\end{itemize}
+
+\section{interfaceSetup}
+
+This is contained within the audioHolder tag and outlines test instance specific requirements. These include the following children tags: title - question title at the top of the page, scaleMin - minimum scale value text, scaleMax - maximum scale value text, scaleMid - halfway scale value text. There is also a preTest tag here allowing for specific questions/statements to be presented before running this specific test.
+
+\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.
+
+\subsection{Attributes}
+None.
+
+\subsection{Elements}
+The question to be presented.
+
+\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. Measures time between successive clicks on the track changer
+\item elementTracker - Return the initial position of each track
+\item elementTrackerFull - Return an enumerated pair of time and position. Track the entire movement of each element position. NOTE: Will override the elementTracker option above and throw an error into the browser console.
+\item elementFlagListenedTo - Return a boolean per elementck to see if the element was listened to
+\item elementFlagMoved - Return a boolean per element to see if the element slider was moved.
+\item elementFlagComments - Return a boolean per element to see if the element has comments.
+\end{itemize}
+
+\section{Feature List}
+\begin{itemize}
+\item Paging listening tests - eg. Ask multiple questions in each experiment
+\item Labels on X axis - scale
+\item Input questions/comment at top to guide towards the question being asked.
+\item Randomise track numbers -(inc. comment boxes and relate back to correct reference track)
+\item Randomise order of individual tests
+\item Save output XML file to remote server
+\item Tests Metrics
+\begin{itemize}
+\item Duration of listening to each track
+\item Time spent on each individual test
+\item Start and end position of every track
+\item Flags on each track, to ensure each track (but may not restrict users from submitting)
+\begin{itemize}
+\item Has been listened to 
+\item Has been moved
+\item Has comments about it
+\end{itemize}
+\end{itemize}
+\end{itemize}
+
+\subsection{Advanced feature list}
+\begin{itemize}
+\item Repeat each tests number of times (2 or 3?) to remove learning / experience bias and ensure that the order is consistent
+\item Perform Loudness equalisation on all tracks
+\item Selection of test type
+\item Pre-test of some basic hearing test
+\begin{itemize}
+\item MUSHRA (with vertical slider per track)
+\item APE (Single horizontal slider)
+\item AB Test
+\end{itemize}
+\end{itemize}
+
+

+\large APE Browser Tool - Results Specification Document
+
+\section{Introduction}
+This document outlines the return XML document structure to hold the results from the Browser Evaluation Tool, specifically for the APE Interface.
+
+\section{Root}
+The root of the document is \texttt{BrowserEvaluationResult}.
+
+\section{testReults}
+A 1st level node, contains all the results from a specific test instance defined by the audioHolder objects in the setup XML. Takes the audioElement as its children to define a full test and any test metrics.
+
+\subsection{Attributes}
+\begin{itemize}
+\item \texttt{id} - The ID given to audioHolder in the project setup XML.
+\item \texttt{repeatCount} - Specifies the repeat count of the test, there will be one testResult per test per repeat, this will help identify which repeat.
+\end{itemize}
+
+\subsection{AudioElement}
+A 2nd level node, this contains the results for a specific audioElement.
+
+\subsubsection{Attributes}
+Has the following attributes, depending on the variables set in the Project Specification.
+\begin{itemize}
+\item \texttt{id} - Mandatory. This returns the ID of the track in question. This is either the value passed in from the project specification, or calculated based on the position in the list. For instance, in the automatic system, the first test sample has ID 0, the second ID 1 and so forth. The value passed in from the project specification can either be a string or a Number.
+\item \texttt{url} - Mandatory. Returns the full URL given incase of errors or for later checking.
+\end{itemize}
+
+\subsubsection{Value}
+One of these elements per track, containing the value between 0 and 100 relating the user rating of the track. This is a mandatory element.
+% float or int? (I, Brecht, am sort of indifferent here, it used to be down to .01 or something before, so maybe that or .1)
+% Nick - Can be a float, was trying to remove/reduce ambiguity from pixel position. But can easily make it to .01
+
+\subsubsection{Comment}
+One of these elements per track, containing any commenting data from the interface text boxes. Has the two following child nodes.
+\begin{itemize}
+\item \texttt{Question} - Returns the text next to the comment box
+\item \texttt{Response} - Returns the text in the comment box
+\end{itemize}
+
+\subsubsection{metrics}
+One of these holders per audioElement, containing the results from any of the enabled per element metrics in metricResult tags. The ID of each element represents the metricEnable tag element. The inner value contains the results.
+
+% Will list specific response structures per metric!
+
+\subsection{metrics}
+One of these holders per testResults tag, containing the results from any of the enabled per test metrics in metricResult tags. The ID of each element represents the metricEnable tag element. The inner value contains the results.
+
+% Will list specific response structures per metric!
+
+\section{PreTest and PostTest}
+A 1st level node, contains the response to any pre-test questions given in the project specification. These are stored in the same Comment node as outlined in the above audioElement.
+
+The PostTest is a 1st level node and contains the response to any post-test questions given in the project specification.
+
+\section{Session Data}
+This will contain any captured session data. Currently not implemented but here for future referencing.
+% I used to have a 'global' comment for each 'session' as well
+
+\section{Globals}
+Contains any comment boxes which were specified in the APE project specification with the comment ID, comment text and the comment results.

+% Changelog:
+%
+% 1.00 (2002/08/13) Initial release
+%
+% 1.10 (2002/09/27)
+%  1. 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. The values used
+% here can be overridden by the user via IEEEtranBSTCTL entry type.
+
+% NOTE: The recommended LaTeX command to invoke a control entry type is:
+% 
+%\makeatletter
+%\def\bstctlcite{\@ifnextchar[{\@bstctlcite}{\@bstctlcite[@auxout]}}
+%\def\@bstctlcite[#1]#2{\@bsphack
+%  \@for\@citeb:=#2\do{%
+%    \edef\@citeb{\expandafter\@firstofone\@citeb}%
+%    \if@filesw\immediate\write\csname #1\endcsname{\string\citation{\@citeb}}\fi}%
+%  \@esphack}
+%\makeatother
+%
+% It is called at the start of the document, before the first \cite, like:
+% \bstctlcite{IEEEexample:BSTcontrol}
+%
+% IEEEtran.cls V1.6 and later does provide this command.
+
+
+
+% #0 turns off the display of the number for articles.
+% #1 enables
+FUNCTION {default.is.use.number.for.article} { #1 }
+
+
+% #0 turns off the display of the paper and type fields in @inproceedings.
+% #1 enables
+FUNCTION {default.is.use.paper} { #1 }
+
+
+% #0 turns off the forced use of "et al."
+% #1 enables
+FUNCTION {default.is.forced.et.al} { #0 }
+
+% The maximum number of names that can be present beyond which an "et al."
+% usage is forced. Be sure that num.names.shown.with.forced.et.al (below)
+% is not greater than this value!
+% Note: There are many instances of references in IEEE journals which have
+% a very large number of authors as well as instances in which "et al." is
+% used profusely.
+FUNCTION {default.max.num.names.before.forced.et.al} { #10 }
+
+% The number of names that will be shown with a forced "et al.".
+% Must be less than or equal to max.num.names.before.forced.et.al
+FUNCTION {default.num.names.shown.with.forced.et.al} { #1 }
+
+
+% #0 turns off the alternate interword spacing for entries with URLs.
+% #1 enables
+FUNCTION {default.is.use.alt.interword.spacing} { #1 }
+
+% If alternate interword spacing for entries with URLs is enabled, this is
+% the interword spacing stretch factor that will be used. For example, the
+% default "4" here means that the interword spacing in entries with URLs can
+% stretch to four times normal. Does not have to be an integer. Note that
+% the value specified here can be overridden by the user in their LaTeX
+% code via a command such as: 
+% "\providecommand\BIBentryALTinterwordstretchfactor{1.5}" in addition to
+% that via the IEEEtranBSTCTL entry type.
+FUNCTION {default.ALTinterwordstretchfactor} { "4" }
+
+
+% #0 turns off the "dashification" of repeated (i.e., identical to those
+% of the previous entry) names. IEEE normally does this.
+% #1 enables
+FUNCTION {default.is.dash.repeated.names} { #1 }
+
+
+% The default name format control string.
+FUNCTION {default.name.format.string}{ "{f.~}{vv~}{ll}{, jj}" }
+
+
+% The default LaTeX font command for the names.
+FUNCTION {default.name.latex.cmd}{ "" }
+
+
+% The default URL prefix.
+FUNCTION {default.name.url.prefix}{ "[Online]. Available:" }
+
+
+% Other controls that cannot be accessed via IEEEtranBSTCTL entry type.
+
+% #0 turns off the terminal startup banner/completed message so as to
+% operate more quietly.
+% #1 enables
+FUNCTION {is.print.banners.to.terminal} { #1 }

+% This IEEEtran.bst features a very powerful and flexible mechanism for
+% controlling the capitalization, punctuation, spacing, quotation, and
+% newlines of the formatted entry fields. (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.

+
+The tool runs entirely inside the browser through the new HTML5 Web Audio API. The API is supported by most major web browsers (except Internet Explorer) and allows for constructing a chain of audio processing elements to produce a high quality, real time signal process to manipulate audio streams. The API supports multi-channel processing and has an accurate playback timer for precise scheduled playback control. The web audio API is controlled through the browser JavaScript and is therefore highly controllable. The Web Audio API processing is all controlled in a separate thread to the main JavaScript thread, meaning there is no blocking due to real time processing.
+
+\subsection{Architecture}\label{sec:architecture}
+
+The web tool itself is split into several files to operate:
+\begin{itemize}
+\item apeTool.html: The main index file to load the scripts, this is the file the browser must request to load
+\item core.js: Contains functions and objects to manage the audio control, audio objects for testing and loading of files
+\item ape.js: Parses setup files to create the interface as instructed, following the same style chain as the MATLAB APE Tool.
+\end{itemize}
+
+The HTML file loads the core.js file with it along with a few other ancillary files (such as the jQuery javascript extensions), the browser JavaScript begins to execute the on page instructions, which gives the URL of the test setup XML document (outlined in the next section). The core.js parses this document and executes the function in ape.js to build the web page with the given audio files. The reason for separating these two files is to allow for further interface designs (such as Mushra or A-B tests) to be used, which would still require the same underlying core functions outlined in core.js
+
+The ape.js file has only two main functions: loadInterface(xmlDoc) and interfaceXMLSave(). The first function is called to build the interface once the setup document has been loaded. This includes creating the slider interface to rate the tracks and creating the comment boxes bellow. The bars in the slider ranking at the top of the page are randomly spaced. It also instructs the audio engine in the core.js to create the audio objects. The audio objects are custom built audio nodes built on the web audio API. They consist of a bufferSourceNode (a node which holds a buffer of audio samples for playback) and a gainNode. These are then connected to the audioEngine (itself a custom web audio node) containing a gainNode (where the various audio Objects connect to) for summation before passing the output to the destination Node, a fixed node created where the browser then passes the audio information to the system sound device.
+
+When an audioObject is created, the URL of the audio sample to load is given to it. This is downloaded into the browser asynchronously using the XMLHttpRequest object. This allows for downloading of any file into the JavaScript environment for further processing. It is particularly useful for the web audio API because it supports downloading of files in their binary form, allowing a perfect copy. Once the asynchronous download is complete, the file is then 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 audioObject bufferSourceNode for playback.
+
+Browsers support various audio file formats and are not consistent in any format. One sure format that all browsers support is the WAV format. Although not a compact, web friendly format, most transport systems are of a high enough bandwidth this should not be a problem. However one problem is that of sample rate. On loading, the browser uses the sample rate assigned by the system sound device. The browser does not have the ability to request a different sound rate. Therefore 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. Only once the sample rates match will the system actually fetch any files, keeping down requests for the larger files until they are actually needed.
+
+During playback, the playback nodes loop indefinitely until playback is stopped. The gain nodes in the audioObjects enable dynamic muting of nodes. When a bar in the sliding ranking is clicked, the audio engine mutes all audioObjects 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.
+
+\subsection{Setup and Results Formats}\label{sec:setupresultsformats}
+
+Setup and the results both use the common XML document format to outline the various parameters. The setup file contains all the information needed to initialise a test session. Several Nodes can be defined to outline the audio samples to use, questions to be asked and any pre- or post-test questions or instructions. 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 which web files.
+
+The results file is dynamically generated by the interface upon clicking the submit button. There will be checks, depending on the setup file, to ensure that all tracks have been evaluated and their positions in the slider moved. The XML returned contains a node per audioObject and contains its rating in the slider and any comments written in its associated comment box. The rating returned is normalised to be within a integer range of 0 to 100. This normalises the pixel representation of different browser windows. If a window for instance is only 1280 wide, reporting its pixel position is not representative to a display with a width of 1920.
+
+The pre- and post-test options allow for comments or questions to be presented before or after the test. These are automatically generated based upon the given setup XML and allow nearly any form of question and comment to be included in a window on its own. Questions are stored and presented in the response section labelled 'pretest' and 'posttest' along with the question ID and its response. Questions can be made optionally mandatory. Example questions may involve entering mixing experience or listening environment.
+
+The results will also contain information collected by any defined pre/post questions. These are referenced against the setup XML by using the same ID as well as printing in the same question, so readable responses can be obtained. Future development will also evolve to include any session data, such as the browser the tool was used in, how long the test took and any other metrics. Currently the results files are downloaded on the user side of the browser as a .xml file to be manually returned. However the end goal is to allow the XML files to be submitted over the web to a receiving server to store them, allowing for automated collection.
+
+Here is an example of the setup XML and the results XML:

+
+\section{Applications}\label{sec:applications} %?
+discussion of use of this toolbox (possibly based on a quick mock test using my research data, to be repeated with a large number of participants and more data later)\\
+
+\subsection{Listening Environment Standardisation}
+
+In order to reduce the impact of having a non-standardised listening environment and unobservable participants, a series of pre-test standard questions have been put together to ask every participant. The first part of this is that every participant is asked to carry out the test, wherever possible, with a pair of quality headphones.
+
+\begin{itemize}
+\item Name (text box)
+\item I am happy for name to be used in an academic publication (check box)
+\item First Language (text box)
+\item Location eg. country, city (text box)
+\item Playback System (ratio box (Headphones or Speaker))
+\item Make and Model of Playback System (text box)
+\item Please assess how good you believe your hearing to be, where 1 is deaf, 10 is professional critical listener (Dropdown box 1-10)
+\end{itemize}
+
+
+There are also a series of considerations that have been made towards ensuring there is a standardised listening environment, so it is possible to
+\begin{itemize}
+\item Begin with standardised listening test - to confirm listening experience
+\item Perform loudness equalisation on all tracks 
+\\** OR THIS SHOULD BE DONE BEFORE THE EXPERIMENT
+\item Randomise order of tests
+\item Randomise order of tracks in each test
+\item Repeat each experiment a number of times 
+\\** TO REMOVE THE FAMILIARISATION WITH EXPERIMENT VARIABLE 
+\\** TO ENSURE CONSISTENCY OF USER
+\item Track all user interactions with system
+\end{itemize}
+
+
+
+
+
+\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. % or something
+
+% future work
+Further work may include the development of other common test designs, such as [...], and [...]. In addition, [...]. 
+
+\begin{itemize}
+\item Options for MUSHRA style experiment with vertical slide per track, APE style experiment where all tracks are on a single horizontal axis, or AB test
