Sonic Visualiser full changelog

Support multi-line text labels on time instants
Improve refresh and rendering of text labels in various layers
Improve abbreviation of layer names in the key at bottom-right of a pane
Fix repeated writes to settings file when rendering time-ruler layers at close zoom levels
Use system Vamp host SDK if provided

Fix failure to activate the Align button on startup, even when the appropriate alignment plugin is installed
Fix (obviously) incorrect colour display for closely zoomed-in colour 3d plot views
Switch the build system from autoconf/qmake/make to meson/ninja

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

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

- 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

- 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

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
