Chris@2002: Chris@2002: Changes in Sonic Visualiser 3.2 since the previous release 3.1.1: Chris@2002: Chris@2048: - Add ability to zoom closer than one sample per pixel, so as to see Chris@2048: the interpolated signal level between samples Chris@2048: Chris@2110: - Add oversampling control to the spectrogram and spectrum layers Chris@2110: Chris@2110: - Highlight and label frequency peaks in the spectrum as the mouse Chris@2110: rolls over them, when enabled in the parameter area Chris@2110: Chris@2002: - Add feature to convert and import audio from a CSV data file Chris@2002: Chris@2048: - Add some new colour maps, and restore the old Blue on Black one Chris@2048: Chris@2110: - Speed up spectrum rendering at high resolutions Chris@2110: Chris@2048: - Fix failure to pass Nyquist bins correctly to Chris@2048: frequency-domain-input Vamp plugins in some circumstances Chris@2048: Chris@2110: - Fix sometimes incorrect shortcut associations for new-layer menu Chris@2110: items Chris@2110: Chris@2139: - Various other rendering improvements and bug fixes Chris@2110: cannam@1948: cannam@1948: Changes in Sonic Visualiser 3.1.1 (Aug 2018) since the previous release 3.1: cannam@1948: cannam@1948: - Fix failure to record correctly into an empty session with certain cannam@1948: audio drivers cannam@1948: Chris@1958: - Fix failure to run LADSPA plugins at all, except with some unusual Chris@1958: path layouts Chris@1958: Chris@1958: - Fix failure to silence sonified notes when rewinding backwards or Chris@1958: jumping back from a loop endpoint Chris@1958: cannam@1948: - Fix macOS .dmg image so as to use older HFS+ filesystem for compatibility cannam@1948: Chris@1871: Chris@1932: Changes in Sonic Visualiser 3.1 (July 2018) since the previous release 3.0.3: Chris@1871: Chris@1871: - Add Plugins tab to Preferences dialog, from which you can review Chris@1871: the plugin load paths and see which plugins were loaded from which Chris@1871: locations, and also customise load paths (though the various path Chris@1871: environment variables are still supported) Chris@1871: Chris@1935: - Stream the export of audio data and other CSV data so that Chris@1935: very large exports don't hang the UI or run us out of memory Chris@1935: (thanks to Lucas Thompson) Chris@1935: Chris@1935: - Ensure vertical scale appears for auto-align layers when there is Chris@1935: nothing else to auto-align them to Chris@1935: Chris@1871: - Fix another long-standing Windows-platform wide-char/utf8 Chris@1871: conversion problem, with environment variable naming and contents Chris@1871: Chris@1871: - Improve handling of incomplete session loads, i.e. situations where Chris@1871: the audio files referred to by a session could not be found - Chris@1871: previously the session could be re-saved immediately thus losing Chris@1871: the audio reference; now at least we disable Save (enabling only Chris@1871: Save As) and show a warning Chris@1871: Chris@1871: - Update pane and layer menu shortcuts so that the Chris@1871: waveform/spectrogram/etc shortcuts (Shift+G etc) operate on the Chris@1871: source model in the currently-selected pane rather than the main Chris@1871: model. This is a backward-incompatible change but is a far more Chris@1871: intuitive way for the function to work Chris@1871: Chris@1935: - Use dark background for bright colours in time-value/note/etc Chris@1935: layers as well as e.g. waveforms - this is how it was always Chris@1935: "intended to" work, but it is a backward-incompatible change Chris@1935: Chris@1871: - Make "Select All" select the whole span of everything that exists, Chris@1871: not just the main model Chris@1871: Chris@1871: - Add horizontal scale to Spectrum layer Chris@1871: Chris@1871: - Improve spacing and labelling of vertical log scales Chris@1871: Chris@1871: - Update build system for better Cap'n Proto version support and to Chris@1871: use Repoint for code management in the repository Chris@1871: Chris@1871: - Various other bug fixes Chris@1871: Chris@1702: Chris@1702: Changes in Sonic Visualiser 3.0.3 (May 2017) since the previous release 3.0.2: Chris@1702: Chris@1702: - Improve decisions about where and how to label vertical scales Chris@1702: Chris@1702: - Update build support material and documentation to reflect the Chris@1702: official release of Cap'n Proto 0.6 (which we can now use rather Chris@1702: than depending on git builds) Chris@1702: Chris@1669: Chris@1669: Changes in Sonic Visualiser 3.0.2 (Mar 2017) since the previous release 3.0.1: Chris@1669: Chris@1669: - Fix crash when changing parameters for spectrum view Chris@1669: Chris@1669: - Fix incorrect measure tool crosshairs in spectrum view Chris@1669: Chris@1669: - Update Russian and Czech UI translations (thanks to Alexandre Prokoudine Chris@1669: and Pavel Fric respectively) Chris@1702: Chris@1658: Chris@1658: Changes in Sonic Visualiser 3.0.1 (Mar 2017) since the previous release 3.0: Chris@1658: Chris@1658: - Fix crashes with MIDI devices and speedup/slowdown control on Windows Chris@1661: Chris@1658: - Update MIDI input driver layer Chris@1447: Chris@1661: Chris@1624: Changes in Sonic Visualiser 3.0 (Mar 2017) since the previous release 2.5: Chris@1447: Chris@1516: - Add ability to record audio, and ability to change the audio device Chris@1516: for playback or recording in the preferences Chris@1447: Chris@1447: - Add complete support for high-resolution (Hi-DPI or retina) Chris@1511: displays, including for layer data rendering as well as UI controls Chris@1511: and icons. This makes the biggest difference when using a retina Chris@1511: Mac, on which previous versions did not render layer data at retina Chris@1447: resolution, but it also improves scaling and rendering of UI Chris@1447: elements on Hi-DPI displays on Windows and Linux Chris@1447: Chris@1451: - Add ability to export scalable (SVG) image files Chris@1451: Chris@1447: - Run plugins in a separate process, so that if a plugin crashes, it Chris@1447: no longer brings down Sonic Visualiser with it. In every other Chris@1447: respect the behaviour should be unchanged Chris@1447: Chris@1447: - Scan plugins on startup in a separate process, and report on any Chris@1447: that crash or won't load Chris@1447: Chris@1527: - Add ability to open, display, and analyse very long audio files (of Chris@1527: more than 2^32 sample frames) Chris@1527: Chris@1447: - Change mp3 file loading so as to compensate for encoder/decoder Chris@1447: delay and padding (using "gapless playback" logic). While this is a Chris@1447: real improvement, unfortunately it does mean that the initial Chris@1447: padding in mp3 file load has changed from previous versions, which Chris@1447: may mean some sessions saved in previous versions are no longer Chris@1447: correctly aligned. It's not a great idea to use mp3 as a file Chris@1447: format of record, because of differences like this between Chris@1447: decoders. The previous behaviour is still available as a preference. Chris@1447: Chris@1470: - Add new Hybrid normalisation type for spectrogram and colour 3d Chris@1470: plot layers. This normalises each column to its peak value and then Chris@1470: scales the normalised values by the log of the peak in order to Chris@1470: restore some distinction in scale between columns with different Chris@1470: levels. It can provide quite visually clear results. Chris@1470: Chris@1447: - Add function to subdivide time instant layers into regular Chris@1447: intervals (and its inverse) Chris@1447: Chris@1447: - Add new preference for default colour scales Chris@1447: Chris@1578: - Add a basic ability to zoom (in the frequency axis) to the spectrum Chris@1624: Chris@1447: - Switch to using combined level/pan controls in layer property boxes Chris@1447: and for the main volume control Chris@1447: Chris@1520: - Make CSV file reader better able to handle files with varying Chris@1520: numbers of columns Chris@1520: Chris@1516: - Fix a number of problems on Windows with loading and saving some Chris@1516: file formats to filenames not representable in system codepage Chris@1516: Chris@1520: - Add "What's New" dialog Chris@1520: Chris@1527: - Finally switch the Windows build to 64-bit by default (with Chris@1447: adapters to run either 32- or 64-bit plugins) Chris@1451: Chris@1447: Chris@1520: Changes in Sonic Visualiser 2.5 (Oct 2015) since the previous release 2.4.1: Chris@1072: Chris@1072: - Add unit-converter dialog, for converting between various pitch and Chris@1072: timing units Chris@1072: Chris@1072: - Fix failure to reload note layers from session file Chris@1072: Chris@1072: - Use a more sensible scale for the play-speed dial Chris@1072: Chris@1072: - Fix crash when importing very wide CSV files Chris@1072: Chris@1072: - Fix generation of wrong layer type from some CSV files Chris@1072: Chris@1072: - Fix failure to export last instant in a time-instant layer Chris@1072: Chris@1457: Chris@1520: Changes in Sonic Visualiser 2.4.1 (Oct 2014) since the previous release 2.4: Chris@876: Chris@876: - Fix a crash when rendering certain colour 3d plot layers Chris@716: Chris@1457: Chris@1520: Changes in Sonic Visualiser 2.4 (Sep 2014) since the previous release 2.3: Chris@714: Chris@776: - Add support for left/right scrolling using a two-finger touchpad Chris@776: gesture (where available) Chris@776: Chris@716: - Make the octave numbering into a configurable option, and change Chris@716: the default. Previously Sonic Visualiser labelled middle-C as "C3"; Chris@716: now it labels middle-C as "C4", a more common standard in the world Chris@776: outside MIDI sequencer software. The previous system is available Chris@776: as an option in the Preferences. This affects only the visible Chris@776: labels: there is no change to analysis or to the file format Chris@714: Chris@714: - Sonify time-value layers. Any time-value curve whose scale unit is Chris@714: set to Hz will now acquire a playback toggle control; this control Chris@714: is off by default, but if it is switched on, the curve will be Chris@714: played back using a variable-frequency sound generator Chris@714: Chris@714: - Add support for playback of note layers with non-MIDI frequencies Chris@714: (formerly the note playback was limited to exact MIDI pitch) Chris@714: Chris@714: - Change the default playback sample for note layers from piano to an Chris@714: electric piano with sustain. The piano sample is still available, Chris@714: and any sessions saved using it should continue to use it Chris@714: Chris@867: - Add a cancel button for Vamp plugin processing: currently, Chris@867: cancelling a transform results in a part-complete layer rather than Chris@867: removing the results Chris@867: Chris@790: - Add keyboard shortcuts to cycle the current layer (in addition to Chris@790: the existing ones to cycle the current pane) Chris@790: Chris@790: - Fix various bugs related to layer ordering: layer tabs re-ordering Chris@790: themselves randomly when new layer added, layers being ordered Chris@791: randomly when saving and reloading a session Chris@790: Chris@848: - Fix incorrect interaction with non-Unicode usernames when creating Chris@848: temporary and template directories on Windows Chris@848: Chris@714: - Shade the start and end of the main audio file, to make them easier Chris@714: to see for files that start or end in silence Chris@714: Chris@714: - Speed up rendering and scrolling in time-value layers Chris@714: Chris@714: - Make it possible to import CSV files directly into Note layers by Chris@714: adding Pitch as a data type in the CSV file import dialog Chris@675: Chris@856: - Fix play pointer jump to wrong frame when clicking on row in the Chris@856: layer edit dialog Chris@856: Chris@848: - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This Chris@848: is the first release in which the official builds use Qt5 for all Chris@848: platforms. Chris@848: Chris@675: Chris@1520: Changes in Sonic Visualiser 2.3 (Dec 2013) since the previous release 2.2: Chris@675: Chris@675: - Add a startup welcome dialog that also explains what SV makes Chris@675: network connections for and allows user to forbid them Chris@675: Chris@675: - Add "Export Audio Data" feature Chris@675: Chris@675: - Show piano keyboard scale in note and time-value layers as well Chris@675: as spectrogram, where vertical scale is log Hz; also show Chris@675: numerical scale in note and region layers when not auto-aligned Chris@675: Chris@675: - Speed up CSV file import and avoid showing crazily wide window Chris@675: for CSV file format dialog when file has lots of columns Chris@675: Chris@675: - Fix incorrectly saved window geometry when exiting from maximised Chris@675: state Chris@675: Chris@675: - Reduce number of timer wakeups when idle Chris@675: Chris@675: - Add American English translation and make choice of translation Chris@675: into a preference (defaulting to system locale) Chris@675: Chris@675: - Permit installation to non-default location with Windows installer Chris@675: build Chris@714: Chris@608: Chris@1520: Changes in Sonic Visualiser 2.2 (July 2013) since the previous release 2.1: Chris@608: Chris@608: - Build with support for hidpi ("retina") text on OS/X Chris@675: Chris@608: - Fix very slow analysis when using Ogg or FLAC files decoded Chris@608: via libsndfile Chris@675: Chris@608: - Fix inaccurate scale auto-align between time-value layers and Chris@608: others Chris@675: Chris@608: - Fix failure to open files specified on command line (or via Chris@608: Open With) on Windows Chris@675: Chris@608: - Reset cyclical counters and switch back to navigate mode when Chris@608: a new session is started Chris@579: Chris@675: Chris@1520: Changes in Sonic Visualiser 2.1 (May 2013) since the previous release 2.0.1: Chris@579: Chris@579: - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix) Chris@675: Chris@579: - Make it easier to see results from transforms that return a single point Chris@675: Chris@579: - Make labelling clearer on time-value layers Chris@675: Chris@579: - Add discrete-curve mode for time-value layers (for curves with gaps) Chris@675: Chris@579: - Update code to build against Qt5 Chris@523: Chris@675: Chris@523: Changes in Sonic Visualiser 2.0.1 since the previous release 2.0: Chris@523: Chris@523: - Fix incorrect samplerate in reading m4a files on OS/X Chris@512: Chris@675: Chris@1520: Changes in Sonic Visualiser 2.0 (July 2012) since the previous release 1.9: Chris@512: Chris@512: - Support 64-bit builds on OS/X (using CoreAudio instead of Chris@512: obsolete QuickTime audio file reader) Chris@512: Chris@512: - Simplify RDF reading and fix some bugs. Now requires Dataquay Chris@512: (http://breakfastquay.com/dataquay/) rather than using Redland Chris@512: directly. Release builds use Sord/Serd rather than Redland Chris@512: Chris@512: - Add a fullscreen mode on the F11 key Chris@471: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.9 (Oct 2011) since the previous release 1.8: Chris@471: Chris@471: - Add session templates; save session as template; apply template to Chris@471: session Chris@471: Chris@471: - Tidy up the file open logic so as to remove the dialog asking how Chris@471: to open a file, where possible Chris@471: Chris@471: - Various bug fixes. Chris@394: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.8 (Apr 2011) since the previous release 1.7.2: Chris@394: Chris@394: - Sonic Visualiser now registers as a file type handler on OS/X, Chris@394: providing better integration with the desktop generally (Dan Stowell) Chris@394: Chris@394: - There is a new function to toggle all Time Rulers at once (key #) Chris@394: Chris@407: - The CSV import dialog has been overhauled, allowing more flexible Chris@407: selection of purpose for each column Chris@407: Chris@394: - Text overlays are now easier to read on dark backgrounds Chris@394: Chris@394: - Hidden layers are now ignored when exporting an image (Dan Stowell) Chris@394: Chris@394: - A crash when starting a new session or exiting the application Chris@394: after loading a session with saved alignment data has been fixed Chris@394: Chris@394: - The duplication of right-button menu functions when multiple files Chris@394: were loaded has been fixed Chris@394: Chris@394: - The layer-add menu functions now have shortcuts (Dan Stowell) Chris@394: Chris@394: - The codebase has been reorganised into libraries and a configure Chris@394: step added. It should be easier to build and maintain on OS/X and Chris@394: Linux than previously, although it won't make much difference on Chris@394: Windows. Chris@394: Chris@397: - A Czech translation is now included (thanks to Pavel Fric). Chris@397: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.7.2 (May 2010) since the previous release 1.7.1: Chris@394: Chris@394: - The time-value layer now has an origin line and an option to Chris@394: show derivatives (change from one point to the next) rather than Chris@394: raw values Chris@394: Chris@394: - A static initialiser race has been fixed, possibly fixing an Chris@394: occasional crash on startup in Windows Chris@394: Chris@394: - A crash when pressing Play straight after New Session has been Chris@394: fixed Chris@394: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.7.1 (Oct 2009) since the previous release 1.7: Chris@394: Chris@394: - The RDF importer does a better job of assigning labels to layers, Chris@394: layers to panes, and values to labelled regions Chris@394: Chris@394: - Interactive editing in the Text layer benefits from the same Chris@394: improvements as made in 1.7 to Note and Region layers Chris@394: Chris@394: - The layer data editor window has a text search feature Chris@394: Chris@394: - The main window status bar now shows the last label to have passed Chris@394: the playback position in the current layer, at the right end of the Chris@394: status bar Chris@394: Chris@394: - The Russian translation has been updated (thanks Alexandre) Chris@394: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.7 (Sep 2009) since the previous release 1.6: Chris@394: Chris@394: - A new "Insert Item At Selection" function on the Edit menu Chris@394: can be used to create Note and Region layer items whose time Chris@394: extents correspond to the current selection(s) Chris@394: Chris@394: - Interactively editing points in the Note and Region layers Chris@394: now works much more smoothly Chris@394: Chris@394: - SV can now import MIDI files that use SMPTE timecode for event Chris@394: timing (importing MIDI files using with the more common Chris@394: timebase-based timing was already supported) Chris@394: Chris@394: - Time values throughout the display may optionally be shown in Chris@394: seconds and frames at various frame rates Chris@1520: Chris@394: - A crash on exit in Windows has been fixed Chris@394: Chris@394: - A very unobtrusive user survey is now included Chris@394: Chris@394: - Various other bug fixes. Chris@394: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.6 (Jun 2009) since the previous release 1.5: Chris@394: Chris@394: - The Colour 3D Plot layer now supports logarithmic vertical Chris@394: scale and linear interpolation options. Chris@394: Chris@394: - A new colour scheme (High Gain) has been added for spectrogram Chris@394: and Colour 3D Plot, which improves readability for some data. Chris@394: Chris@394: - Further performance improvements have been made to Colour 3D Chris@394: Plot. Chris@394: Chris@394: - Various other bug fixes. Chris@394: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.5 (Mar 2009) since the previous release 1.4: Chris@394: Chris@394: - You can now insert time instants, time values, and notes using Chris@394: a MIDI device during playback. If a time value or note layer is Chris@394: current it will be used for insertion (giving a value equal to Chris@394: the pitch class, or the played note, respectively); otherwise an Chris@394: existing or new time instants layer will be used just as it is Chris@394: when inserting instants using the PC keyboard. Using a MIDI Chris@394: device should give better timing than using the PC keyboard. Chris@394: Chris@394: - There is a new Activity Log window with a (purely informative) list Chris@394: of events and user interactions that happen while SV is running. Chris@394: Chris@394: - The spectrogram has somewhat improved graphical scaling, and Chris@394: this is now the default (being much faster than the 4x oversampled Chris@394: method). The previous default is still available as a preference. Chris@394: Chris@394: - Visualisation of very dense colour plots (such as spectrograms Chris@394: calculated by plugins) is substantially faster in this release. Chris@394: Chris@394: - Spectrogram display is now faster in many circumstances. Chris@394: Chris@394: - Alignment using the MATCH plugin is faster on OS/X than before. Chris@394: Chris@394: - SV will take into account RDF plugin descriptions, if available, Chris@394: in order to make somewhat better decisions about display of plugin Chris@394: outputs (for example, placing segmentation data into a layer with Chris@394: segmentation plot type). Chris@394: Chris@394: - You can now switch layers by clicking on the spare area at the left Chris@394: end of the pane that is also used for the current pane indicator. Chris@394: Chris@394: - The vertical black lines dividing segments in the time value Chris@394: layer's segmentation plot style are now optional. Chris@394: Chris@394: - Several widget layout bugs on OS/X have been fixed. Chris@394: Chris@394: - Several serious crashing, deadlock, and data corruption bugs have Chris@394: been fixed. Chris@394: Chris@394: Chris@1520: Changes in Sonic Visualiser 1.4 (Dec 2008) since the previous release 1.3: Chris@394: Chris@394: - SV now has a Region layer type, used for display of features with Chris@394: durations. It also supports Vamp v2.0 plugins that provide durations Chris@394: for features. Chris@394: Chris@394: - Layer data can now be imported from RDF described using the Audio Chris@394: Features Ontology, as well as from the existing text file types. SV Chris@394: can also export annotation layer data to RDF/Turtle, although in a Chris@394: somewhat simplistic manner at present. Chris@394: Chris@394: - You can search for transforms by text in the new "Find a Transform" Chris@394: dialog. This searches both installed plugins, and plugins that have Chris@394: not been installed but that have descriptions available on the Chris@394: semantic web. Chris@394: Chris@394: - You can now zoom and scroll vertically in the time-value, note, Chris@394: and colour 3d plot layers. Chris@394: Chris@394: - Sonic Visualiser can now load sessions from uncompressed XML files Chris@394: as well as its own compressed-XML .sv format. Files with extension Chris@394: .xml that contain suitable session data will be loaded as sessions. Chris@394: Note that .xml extension files still do not show up in the default Chris@394: file load filter. This is intentional, as there may be any kind of Chris@394: data in them -- if you want to load uncompressed session files from Chris@394: XML, you need to know you're doing it. Chris@394: Chris@394: - Several crashes and other bugs have been fixed. Chris@394: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.3 (Jul 2008) since the previous release 1.2: Chris@394: Chris@394: - There is a new spreadsheet-style data viewer and editor for Chris@394: viewing and editing the data in some types of annotation layer. Chris@394: Chris@394: - Alignments are now saved to the session file. Chris@394: Chris@394: - The spectrogram layer is usually somewhat faster than it was. Chris@394: Chris@394: - You can now hold Shift while dragging to move an item, in order Chris@394: to override the initial drag resistance introduced in 1.2. Chris@394: Chris@394: - The gross mis-labelling of time lines in the ruler has been fixed. Chris@394: Chris@394: - There is a new, somewhat provisional PulseAudio output driver. Chris@394: Chris@394: - Several other bug fixes. Chris@394: Chris@675: Chris@1520: Changes in Sonic Visualiser 1.2 (Feb 2008) since the previous release 1.0: Chris@394: Chris@394: - SV now supports time-alignment of multiple performances of a work Chris@394: loaded at the same time. This option is enabled when the MATCH Vamp Chris@394: plugin is installed. When alignment is switched on and more than one Chris@394: audio file is open, SV will assume that all open files are Chris@394: differently timed performances of the same work, and will calculate Chris@394: time alignments for them. Playback will then play only a single file Chris@394: at a time, and the playback cursors in other files will track at the Chris@394: varying speeds to try to ensure that each is at the same point in the Chris@394: underlying score. This enables effective comparison of several such Chris@394: files, as well as a meaningful way to switch from one performance to Chris@394: another during playback (ensuring that the switch happens at the Chris@394: correct point in the performance being switched to). Chris@394: Chris@394: - There is a new Image layer, which can display images from the Chris@394: local filesystem or retrieved via HTTP or FTP. Chris@394: Chris@394: - A new measurement tool has been added. With the measurement tool Chris@394: selected, dragging in a pane draws a rectangle labelled with the Chris@394: scale values for its start and end corners and its size. You can Chris@394: have any number of measurements present at once; they are associated Chris@394: with the top layer, their scale values depend on the scale for that Chris@394: layer, and they are only shown when that layer is at the top and the Chris@394: measurement tool is active. Measurements are saved and reloaded in Chris@394: the session file. Drawing measurements can be undone and redone, and Chris@394: a measurement can be deleted by hitting Del when highlighted. Note Chris@394: that the measurement tool shows the scale values associated with the Chris@394: pixel positions of the mouse when dragging, not any values associated Chris@394: with actual features present in the audio or its analysis (e.g. the Chris@394: values are not rounded to the nearest spectrogram bin). Chris@394: Chris@394: - You can double-click using the measurement tool in the spectrogram Chris@394: to get an instant measurement rectangle for a feature. This is a Chris@394: purely graphical feature that works by calculating the boundary of a Chris@394: contiguous region of pixels "similar to" the one you double-clicked Chris@394: on; it does not use audio analysis. Adjusting the gain and colour Chris@394: scheme etc of the spectrogram will (by design) affect the Chris@394: measurements obtained this way. Chris@394: Chris@394: - The spectrum can now optionally show frequency estimates of peaks Chris@394: aligned with a piano keyboard along the horizontal axis (this needs Chris@394: some refinement). Chris@394: Chris@394: - The harmonic cursor in the spectrogram has moved from the Select Chris@394: tool to the Measurement tool. There is now a similar harmonic cursor Chris@394: in the spectrum. Both of them show more information as text Chris@394: alongside the cursor than previously. Chris@394: Chris@394: - There is a new Erase tool for erasing individual points from an Chris@394: editable layer. Chris@394: Chris@394: - Several keyboard shortcuts have changed -- all of the Alt+key Chris@394: shortcuts now either use Ctrl or a plain keypress with no modifier, Chris@394: to avoid clashes with window manager shortcuts and to make them Chris@394: easier to use and remember Chris@394: Chris@394: - The playback controls are now in a Playback menu as well as the Chris@394: toolbar. Chris@394: Chris@394: - There is a new key and mouse control reference under Help (or press Chris@394: F2). Chris@394: Chris@394: - You can double-click on a pane in navigate mode to jump to a time. Chris@394: Chris@394: - All of the single-colour layers (waveform, time values etc) now Chris@394: allow you to define your own colours as well as using the built-in Chris@394: set. The colour of a layer is now shown next to its name on the pane. Chris@394: Chris@394: - When you add a new single-colour layer it will use a default colour Chris@394: that is not yet in use in another layer (if there is one). Chris@394: Chris@394: - Single-colour layers can now optionally have black backgrounds (with Chris@394: a set of lighter colours in the default colour palette that use black Chris@394: backgrounds by default). Chris@394: Chris@394: - There's a new Printer colour scheme in the spectrogram with only a Chris@394: small number of grey shades. Chris@394: Chris@394: - Vertical zoom in a log-scaled spectrogram is much more intuitive; Chris@394: it now leaves the point that was in the centre of the visible area in Chris@394: the centre after zoom, instead of the point that was in the centre of Chris@394: the linear range corresponding to the visible area. Chris@394: Chris@394: - You can now turn a colour 3d plot layer upside down by clicking the Chris@394: Invert Vertical Scale button. Chris@394: Chris@394: - There's a new Layer Summary window which shows the panes and Chris@394: layer data in a tree layout. This is very simplistic at the moment. Chris@394: Chris@394: - Each pane now has an [X] button at its top left, which removes that Chris@394: pane when clicked. Chris@394: Chris@394: - There's a new Solo play mode toggle button; when active, only the Chris@394: currently selected pane is played. This is also the default when Chris@394: time alignment is in use. Chris@394: Chris@394: - Rewind/ffwd now stay confined to the selection if Play Selection is Chris@394: enabled; also, the rewind and ffwd "one step" buttons are now enabled Chris@394: even if there is no time instants layer for them to align to (they Chris@394: align to the time ruler instead and so jump in steps of a size Chris@394: dependent on the zoom level). Chris@394: Chris@394: - You can now export note layers to MIDI. Chris@394: Chris@394: - MIDI note velocity is partially supported. Note velocity is Chris@394: retained when importing and exporting MIDI and is used in playback, Chris@394: but it is not yet shown in the display and cannot yet be edited. Chris@394: Chris@394: - You can now drag-and-drop files (of whatever type) onto SV from Chris@394: other programs such as file managers or web browsers. Chris@394: Chris@394: - mp3 files (and Ogg, but they aren't supported on Windows at the Chris@394: moment) are now decoded in a background thread so you can see the Chris@394: start of the track without waiting for the rest to decode. Chris@394: Chris@394: - Mac builds of SV can now load AAC/mp4 files and anything else Chris@394: supported by QuickTime. Chris@394: Chris@394: - There is now an option to resample audio files on import if they Chris@394: don't match the samplerate of the first file loaded. By default this Chris@394: is switched off, as it affects the visible waveform. The default Chris@394: behaviour is unchanged (play at the wrong rate). There is still no Chris@394: option to handle multiple rates "correctly" (i.e. by resampling Chris@394: on playback and showing the waveforms at different resolutions Chris@394: according to each one's underlying rate) and there probably never Chris@394: will be. Chris@394: Chris@394: - SV can now open .m3u playlist files, though it's a hazardous thing Chris@394: to do as it simply loads all the files in the playlist at once. Chris@394: Chris@394: - SV now has various options for how to number tapped time instants Chris@394: (bar/beat, plain counter, time in seconds, tempo etc). Chris@394: Chris@394: - The official builds use Qt 4.3, which fixes some nasty Chris@394: bugs in the file dialog that the version 1.0 builds suffered from. Chris@394:
