Changes in Sonic Visualiser v4.2 (14 August 2020) since the previous release 4.1: - Speed up startup, especially on Windows and especially when a lot of plugins are installed. Plugins are now scanned after the main window has been displayed, and the Transform menus are populated dynamically when the results are available. - Fix incompatibility of 64-bit Windows build with Windows 7 Changes in Sonic Visualiser v4.1 (18 June 2020) since the previous release 4.0.1: - Support "dark mode" on Windows and Linux as well as macOS - Add right-click (or Ctrl-click, on the Mac) context menus to the layer property tabs, pane zoom controls, and all dial controls, providing some basic edit and reset functions - Provide format options when exporting layers to CSV, allowing control over column separator, header row, and timestamp format - Permit and handle optional header row when importing from CSV - Add export of spectrogram data to CSV formats - Support doubling escapes for quotes in quoted CSV fields on import - Fix truncated image export when exporting from spectrogram view that hasn't finished loading when the export is requested - Fix failure to show parameter updates when changing the current program in a Vamp plugin that supports programs (e.g. Melodia) - Fix inability of Windows builds to open https:// URLs - Add references to Vamp Plugin Pack in "Find a Transform" results for plugins that are not yet installed but are available in pack - Improve and tidy various aspects of OSC support, and update documentation for it - Improve performance of peak-frequency spectrogram - Fix missing undo/redo of layer renames - Fix failure to audition effects plugins live, while adjusting their parameters in preparation for applying them - this worked in some cases, but not the most common ones; it should now work everywhere Changes in Sonic Visualiser v4.0.1 (10 Dec 2019) since the previous release 4.0: - Fix nonsense vertical scale in NoteLayer when displaying a model with non-Hz scale (e.g. from an analysis plugin that outputs MIDI note values) - Fix failure to open playback device when using macOS Catalina with certain audio devices - Fix failure to make installed executables executable when compiling and installing the source package Changes in Sonic Visualiser v4.0 (25 Oct 2019) since the previous release 3.3: - Add Box annotation layer type, typically used for time-frequency boxes to be annotated over a spectrogram. Because this introduces a new layer type into the session file format, the major version number has been bumped to v4.0. Sessions saved from v4.0 can still be opened in earlier versions of Sonic Visualiser, but any Box layers will not be loaded - Fix behaviour of auto-align layers on top of waveform: they can now be aligned in the vertical scale, if they have a unit of V and the waveform is of a single channel in linear or dB mode - Make the UI more readable in macOS "dark mode" - Fix sluggishness in starting and stopping playback when using PulseAudio v13.0+ Changes in Sonic Visualiser v3.3 (21 May 2019) since the previous release 3.2.1: - Add support for reading the Opus audio codec on all platforms - Add support for WMA and AAC formats on 64-bit Windows. (AAC was already supported on macOS.) Note that AAC support on Windows does not support "gapless" import, i.e. removing the encoder gaps at start and end of the stream - Add ability to choose the field separator when importing CSV and CSV-like files, if more than one possible candidate separator is found in the file - Fix crash when closing session or starting a new session while calculating alignment of multiple audio files - Fix crash when running certain plugins that call for frequency-domain input at non-power-of-two block sizes - Fix wandering left edge of measure-tool rectangle while dragging out the area - Ensure that plugin stderr debug output is logged to the SV log file Changes in Sonic Visualiser 3.2.1 (07 Jan 2019) since the previous release 3.2: - Fix failure to record from built-in microphone on macOS 10.14 (caused by lack of microphone permission request text) - Fix crash when closing SV or starting a new session during recording - Fix crash on exit in some builds that disable OSC support - Fix flashing effect when scrolling certain configurations of colour 3d plot layer leftwards Changes in Sonic Visualiser 3.2 (07 Dec 2018) since the previous release 3.1.1: - Add ability to zoom closer than one sample per pixel, so as to see the interpolated signal level between samples - Add oversampling control to the spectrogram and spectrum layers - Highlight and label frequency peaks in the spectrum as the mouse rolls over them, when enabled in the parameter area - Add feature to convert and import audio from a CSV data file - Add some new colour maps, and restore the old Blue on Black one - Speed up spectrum rendering at high resolutions - Fix failure to pass Nyquist bins correctly to frequency-domain-input Vamp plugins in some circumstances - Fix sometimes incorrect shortcut associations for new-layer menu items - Various other rendering improvements and bug fixes Changes in Sonic Visualiser 3.1.1 (14 Aug 2018) since the previous release 3.1: - Fix failure to record correctly into an empty session with certain audio drivers - Fix failure to run LADSPA plugins at all, except with some unusual path layouts - Fix failure to silence sonified notes when rewinding backwards or jumping back from a loop endpoint - Fix macOS .dmg image so as to use older HFS+ filesystem for compatibility Changes in Sonic Visualiser 3.1 (14 July 2018) since the previous release 3.0.3: - Add Plugins tab to Preferences dialog, from which you can review the plugin load paths and see which plugins were loaded from which locations, and also customise load paths (though the various path environment variables are still supported) - Stream the export of audio data and other CSV data so that very large exports don't hang the UI or run us out of memory (thanks to Lucas Thompson) - Ensure vertical scale appears for auto-align layers when there is nothing else to auto-align them to - Fix another long-standing Windows-platform wide-char/utf8 conversion problem, with environment variable naming and contents - Improve handling of incomplete session loads, i.e. situations where the audio files referred to by a session could not be found - previously the session could be re-saved immediately thus losing the audio reference; now at least we disable Save (enabling only Save As) and show a warning - Update pane and layer menu shortcuts so that the waveform/spectrogram/etc shortcuts (Shift+G etc) operate on the source model in the currently-selected pane rather than the main model. This is a backward-incompatible change but is a far more intuitive way for the function to work - Use dark background for bright colours in time-value/note/etc layers as well as e.g. waveforms - this is how it was always "intended to" work, but it is a backward-incompatible change - Make "Select All" select the whole span of everything that exists, not just the main model - Add horizontal scale to Spectrum layer - Improve spacing and labelling of vertical log scales - Update build system for better Cap'n Proto version support and to use Repoint for code management in the repository - Various other bug fixes Changes in Sonic Visualiser 3.0 (Mar 2017) since the previous release 2.5: - Add ability to record audio, and ability to change the audio device for playback or recording in the preferences - Add complete support for high-resolution (Hi-DPI or retina) displays, including for layer data rendering as well as UI controls and icons. This makes the biggest difference when using a retina Mac, on which previous versions did not render layer data at retina resolution, but it also improves scaling and rendering of UI elements on Hi-DPI displays on Windows and Linux - Add ability to export scalable (SVG) image files - Run plugins in a separate process, so that if a plugin crashes, it no longer brings down Sonic Visualiser with it. In every other respect the behaviour should be unchanged - Scan plugins on startup in a separate process, and report on any that crash or won't load - Add ability to open, display, and analyse very long audio files (of more than 2^32 sample frames) - Change mp3 file loading so as to compensate for encoder/decoder delay and padding (using "gapless playback" logic). While this is a real improvement, unfortunately it does mean that the initial padding in mp3 file load has changed from previous versions, which may mean some sessions saved in previous versions are no longer correctly aligned. It's not a great idea to use mp3 as a file format of record, because of differences like this between decoders. The previous behaviour is still available as a preference. - Add new Hybrid normalisation type for spectrogram and colour 3d plot layers. This normalises each column to its peak value and then scales the normalised values by the log of the peak in order to restore some distinction in scale between columns with different levels. It can provide quite visually clear results. - Add function to subdivide time instant layers into regular intervals (and its inverse) - Add new preference for default colour scales - Add a basic ability to zoom (in the frequency axis) to the spectrum - Switch to using combined level/pan controls in layer property boxes and for the main volume control - Make CSV file reader better able to handle files with varying numbers of columns - Fix a number of problems on Windows with loading and saving some file formats to filenames not representable in system codepage - Add "What's New" dialog - Finally switch the Windows build to 64-bit by default (with adapters to run either 32- or 64-bit plugins) Changes in Sonic Visualiser 2.5 since the previous release 2.4.1: - Add unit-converter dialog, for converting between various pitch and timing units - Fix failure to reload note layers from session file - Use a more sensible scale for the play-speed dial - Fix crash when importing very wide CSV files - Fix generation of wrong layer type from some CSV files - Fix failure to export last instant in a time-instant layer Changes in Sonic Visualiser 2.4.1 since the previous release 2.4: - Fix a crash when rendering certain colour 3d plot layers Changes in Sonic Visualiser 2.4 since the previous release 2.3: - Add support for left/right scrolling using a two-finger touchpad gesture (where available) - Make the octave numbering into a configurable option, and change the default. Previously Sonic Visualiser labelled middle-C as "C3"; now it labels middle-C as "C4", a more common standard in the world outside MIDI sequencer software. The previous system is available as an option in the Preferences. This affects only the visible labels: there is no change to analysis or to the file format - Sonify time-value layers. Any time-value curve whose scale unit is set to Hz will now acquire a playback toggle control; this control is off by default, but if it is switched on, the curve will be played back using a variable-frequency sound generator - Add support for playback of note layers with non-MIDI frequencies (formerly the note playback was limited to exact MIDI pitch) - Change the default playback sample for note layers from piano to an electric piano with sustain. The piano sample is still available, and any sessions saved using it should continue to use it - Add a cancel button for Vamp plugin processing: currently, cancelling a transform results in a part-complete layer rather than removing the results - Add keyboard shortcuts to cycle the current layer (in addition to the existing ones to cycle the current pane) - Fix various bugs related to layer ordering: layer tabs re-ordering themselves randomly when new layer added, layers being ordered randomly when saving and reloading a session - Fix incorrect interaction with non-Unicode usernames when creating temporary and template directories on Windows - Shade the start and end of the main audio file, to make them easier to see for files that start or end in silence - Speed up rendering and scrolling in time-value layers - Make it possible to import CSV files directly into Note layers by adding Pitch as a data type in the CSV file import dialog - Fix play pointer jump to wrong frame when clicking on row in the layer edit dialog - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This is the first release in which the official builds use Qt5 for all platforms. Changes in Sonic Visualiser 2.3 since the previous release 2.2: - Add a startup welcome dialog that also explains what SV makes network connections for and allows user to forbid them - Add "Export Audio Data" feature - Show piano keyboard scale in note and time-value layers as well as spectrogram, where vertical scale is log Hz; also show numerical scale in note and region layers when not auto-aligned - Speed up CSV file import and avoid showing crazily wide window for CSV file format dialog when file has lots of columns - Fix incorrectly saved window geometry when exiting from maximised state - Reduce number of timer wakeups when idle - Add American English translation and make choice of translation into a preference (defaulting to system locale) - Permit installation to non-default location with Windows installer build Changes in Sonic Visualiser 2.2 since the previous release 2.1: - Build with support for hidpi ("retina") text on OS/X - Fix very slow analysis when using Ogg or FLAC files decoded via libsndfile - Fix inaccurate scale auto-align between time-value layers and others - Fix failure to open files specified on command line (or via Open With) on Windows - Reset cyclical counters and switch back to navigate mode when a new session is started Changes in Sonic Visualiser 2.1 since the previous release 2.0.1: - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix) - Make it easier to see results from transforms that return a single point - Make labelling clearer on time-value layers - Add discrete-curve mode for time-value layers (for curves with gaps) - Update code to build against Qt5 Changes in Sonic Visualiser 2.0.1 since the previous release 2.0: - Fix incorrect samplerate in reading m4a files on OS/X Changes in Sonic Visualiser 2.0 since the previous release 1.9: - Support 64-bit builds on OS/X (using CoreAudio instead of obsolete QuickTime audio file reader) - Simplify RDF reading and fix some bugs. Now requires Dataquay (http://breakfastquay.com/dataquay/) rather than using Redland directly. Release builds use Sord/Serd rather than Redland - Add a fullscreen mode on the F11 key Changes in Sonic Visualiser 1.9 since the previous release 1.8: - Add session templates; save session as template; apply template to session - Tidy up the file open logic so as to remove the dialog asking how to open a file, where possible - Various bug fixes. Changes in Sonic Visualiser 1.8 since the previous release 1.7.2: - Sonic Visualiser now registers as a file type handler on OS/X, providing better integration with the desktop generally (Dan Stowell) - There is a new function to toggle all Time Rulers at once (key #) - The CSV import dialog has been overhauled, allowing more flexible selection of purpose for each column - Text overlays are now easier to read on dark backgrounds - Hidden layers are now ignored when exporting an image (Dan Stowell) - A crash when starting a new session or exiting the application after loading a session with saved alignment data has been fixed - The duplication of right-button menu functions when multiple files were loaded has been fixed - The layer-add menu functions now have shortcuts (Dan Stowell) - The codebase has been reorganised into libraries and a configure step added. It should be easier to build and maintain on OS/X and Linux than previously, although it won't make much difference on Windows. - A Czech translation is now included (thanks to Pavel Fric). Changes in Sonic Visualiser 1.7.2 since the previous release 1.7.1: - The time-value layer now has an origin line and an option to show derivatives (change from one point to the next) rather than raw values - A static initialiser race has been fixed, possibly fixing an occasional crash on startup in Windows - A crash when pressing Play straight after New Session has been fixed Changes in Sonic Visualiser 1.7.1 since the previous release 1.7: - The RDF importer does a better job of assigning labels to layers, layers to panes, and values to labelled regions - Interactive editing in the Text layer benefits from the same improvements as made in 1.7 to Note and Region layers - The layer data editor window has a text search feature - The main window status bar now shows the last label to have passed the playback position in the current layer, at the right end of the status bar - The Russian translation has been updated (thanks Alexandre) Changes in Sonic Visualiser 1.7 since the previous release 1.6: - A new "Insert Item At Selection" function on the Edit menu can be used to create Note and Region layer items whose time extents correspond to the current selection(s) - Interactively editing points in the Note and Region layers now works much more smoothly - SV can now import MIDI files that use SMPTE timecode for event timing (importing MIDI files using with the more common timebase-based timing was already supported) - Time values throughout the display may optionally be shown in seconds and frames at various frame rates - A crash on exit in Windows has been fixed - A very unobtrusive user survey is now included - Various other bug fixes. Changes in Sonic Visualiser 1.6 since the previous release 1.5: - The Colour 3D Plot layer now supports logarithmic vertical scale and linear interpolation options. - A new colour scheme (High Gain) has been added for spectrogram and Colour 3D Plot, which improves readability for some data. - Further performance improvements have been made to Colour 3D Plot. - Various other bug fixes. Changes in Sonic Visualiser 1.5 since the previous version 1.4: - You can now insert time instants, time values, and notes using a MIDI device during playback. If a time value or note layer is current it will be used for insertion (giving a value equal to the pitch class, or the played note, respectively); otherwise an existing or new time instants layer will be used just as it is when inserting instants using the PC keyboard. Using a MIDI device should give better timing than using the PC keyboard. - There is a new Activity Log window with a (purely informative) list of events and user interactions that happen while SV is running. - The spectrogram has somewhat improved graphical scaling, and this is now the default (being much faster than the 4x oversampled method). The previous default is still available as a preference. - Visualisation of very dense colour plots (such as spectrograms calculated by plugins) is substantially faster in this release. - Spectrogram display is now faster in many circumstances. - Alignment using the MATCH plugin is faster on OS/X than before. - SV will take into account RDF plugin descriptions, if available, in order to make somewhat better decisions about display of plugin outputs (for example, placing segmentation data into a layer with segmentation plot type). - You can now switch layers by clicking on the spare area at the left end of the pane that is also used for the current pane indicator. - The vertical black lines dividing segments in the time value layer's segmentation plot style are now optional. - Several widget layout bugs on OS/X have been fixed. - Several serious crashing, deadlock, and data corruption bugs have been fixed. New features in Sonic Visualiser 1.4 since the previous version 1.3: - SV now has a Region layer type, used for display of features with durations. It also supports Vamp v2.0 plugins that provide durations for features. - Layer data can now be imported from RDF described using the Audio Features Ontology, as well as from the existing text file types. SV can also export annotation layer data to RDF/Turtle, although in a somewhat simplistic manner at present. - You can search for transforms by text in the new "Find a Transform" dialog. This searches both installed plugins, and plugins that have not been installed but that have descriptions available on the semantic web. - You can now zoom and scroll vertically in the time-value, note, and colour 3d plot layers. - Sonic Visualiser can now load sessions from uncompressed XML files as well as its own compressed-XML .sv format. Files with extension .xml that contain suitable session data will be loaded as sessions. Note that .xml extension files still do not show up in the default file load filter. This is intentional, as there may be any kind of data in them -- if you want to load uncompressed session files from XML, you need to know you're doing it. - Several crashes and other bugs have been fixed. Changes in Sonic Visualiser 1.3 since the previous version 1.2: - There is a new spreadsheet-style data viewer and editor for viewing and editing the data in some types of annotation layer. - Alignments are now saved to the session file. - The spectrogram layer is usually somewhat faster than it was. - You can now hold Shift while dragging to move an item, in order to override the initial drag resistance introduced in 1.2. - The gross mis-labelling of time lines in the ruler has been fixed. - There is a new, somewhat provisional PulseAudio output driver. - Several other bug fixes. New features in Sonic Visualiser 1.2, since the previous version 1.0: - SV now supports time-alignment of multiple performances of a work loaded at the same time. This option is enabled when the MATCH Vamp plugin is installed. When alignment is switched on and more than one audio file is open, SV will assume that all open files are differently timed performances of the same work, and will calculate time alignments for them. Playback will then play only a single file at a time, and the playback cursors in other files will track at the varying speeds to try to ensure that each is at the same point in the underlying score. This enables effective comparison of several such files, as well as a meaningful way to switch from one performance to another during playback (ensuring that the switch happens at the correct point in the performance being switched to). - There is a new Image layer, which can display images from the local filesystem or retrieved via HTTP or FTP. - A new measurement tool has been added. With the measurement tool selected, dragging in a pane draws a rectangle labelled with the scale values for its start and end corners and its size. You can have any number of measurements present at once; they are associated with the top layer, their scale values depend on the scale for that layer, and they are only shown when that layer is at the top and the measurement tool is active. Measurements are saved and reloaded in the session file. Drawing measurements can be undone and redone, and a measurement can be deleted by hitting Del when highlighted. Note that the measurement tool shows the scale values associated with the pixel positions of the mouse when dragging, not any values associated with actual features present in the audio or its analysis (e.g. the values are not rounded to the nearest spectrogram bin). - You can double-click using the measurement tool in the spectrogram to get an instant measurement rectangle for a feature. This is a purely graphical feature that works by calculating the boundary of a contiguous region of pixels "similar to" the one you double-clicked on; it does not use audio analysis. Adjusting the gain and colour scheme etc of the spectrogram will (by design) affect the measurements obtained this way. - The spectrum can now optionally show frequency estimates of peaks aligned with a piano keyboard along the horizontal axis (this needs some refinement). - The harmonic cursor in the spectrogram has moved from the Select tool to the Measurement tool. There is now a similar harmonic cursor in the spectrum. Both of them show more information as text alongside the cursor than previously. - There is a new Erase tool for erasing individual points from an editable layer. - Several keyboard shortcuts have changed -- all of the Alt+key shortcuts now either use Ctrl or a plain keypress with no modifier, to avoid clashes with window manager shortcuts and to make them easier to use and remember - The playback controls are now in a Playback menu as well as the toolbar. - There is a new key and mouse control reference under Help (or press F2). - You can double-click on a pane in navigate mode to jump to a time. - All of the single-colour layers (waveform, time values etc) now allow you to define your own colours as well as using the built-in set. The colour of a layer is now shown next to its name on the pane. - When you add a new single-colour layer it will use a default colour that is not yet in use in another layer (if there is one). - Single-colour layers can now optionally have black backgrounds (with a set of lighter colours in the default colour palette that use black backgrounds by default). - There's a new Printer colour scheme in the spectrogram with only a small number of grey shades. - Vertical zoom in a log-scaled spectrogram is much more intuitive; it now leaves the point that was in the centre of the visible area in the centre after zoom, instead of the point that was in the centre of the linear range corresponding to the visible area. - You can now turn a colour 3d plot layer upside down by clicking the Invert Vertical Scale button. - There's a new Layer Summary window which shows the panes and layer data in a tree layout. This is very simplistic at the moment. - Each pane now has an [X] button at its top left, which removes that pane when clicked. - There's a new Solo play mode toggle button; when active, only the currently selected pane is played. This is also the default when time alignment is in use. - Rewind/ffwd now stay confined to the selection if Play Selection is enabled; also, the rewind and ffwd "one step" buttons are now enabled even if there is no time instants layer for them to align to (they align to the time ruler instead and so jump in steps of a size dependent on the zoom level). - You can now export note layers to MIDI. - MIDI note velocity is partially supported. Note velocity is retained when importing and exporting MIDI and is used in playback, but it is not yet shown in the display and cannot yet be edited. - You can now drag-and-drop files (of whatever type) onto SV from other programs such as file managers or web browsers. - mp3 files (and Ogg, but they aren't supported on Windows at the moment) are now decoded in a background thread so you can see the start of the track without waiting for the rest to decode. - Mac builds of SV can now load AAC/mp4 files and anything else supported by QuickTime. - There is now an option to resample audio files on import if they don't match the samplerate of the first file loaded. By default this is switched off, as it affects the visible waveform. The default behaviour is unchanged (play at the wrong rate). There is still no option to handle multiple rates "correctly" (i.e. by resampling on playback and showing the waveforms at different resolutions according to each one's underlying rate) and there probably never will be. - SV can now open .m3u playlist files, though it's a hazardous thing to do as it simply loads all the files in the playlist at once. - SV now has various options for how to number tapped time instants (bar/beat, plain counter, time in seconds, tempo etc). - The official builds use Qt 4.3, which fixes some nasty bugs in the file dialog that the version 1.0 builds suffered from.
