Sonic Visualiser audio analysis software updated to v2.3

Sonic Visualiser

The Sonic Visualiser application for viewing and analysing the contents of music audio files, has been updated to version 2.3.

The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.

We hope Sonic Visualiser will be of particular interest to musicologists, archivists, signal-processing researchers and anyone else looking for a friendly way to take a look at what lies inside the audio file.

Changes in Sonic Visualiser v2.3

  • 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.

Sonic Visualiser is available to download for Windows, Mac, and Linux.

Sonic Visualiser updated to v1.8

Sonic Visualiser

Sonic Visualiser, an application for viewing and analysing the contents of music audio files, was recently updated to version 1.8.

The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.

Changes in Sonic Visualiser v1.8

  • 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).

Sonic Visualiser is distributed under the GNU General Public License (v2 or later) and available for Linux, OS/X, and Windows.

Sonic Visualiser updated to v1.7

Sonic Visualiser

Chris Cannam of the Centre for Digital Music at Queen Mary, University of London, has released version 1.7 of Sonic Visualiser, an application for inspecting and analysing the contents of music audio files, combining powerful waveform and spectral visualisation tools with automated feature extraction plugins and annotation capabilities.

The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.

We hope Sonic Visualiser will be of particular interest to musicologists, archivists, signal-processing researchers and anyone else looking for a friendly way to take a look at what lies inside the audio file.

Changes in Sonic Visualiser v1.7

  • 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.

Sonic Visualiser is available as freeware (GNU General Public License) for Windows, Mac and Linux.

Sonic Visualiser updated to v1.6

Sonic Visualiser

Chris Cannam has released version 1.6 of Sonic Visualiser, an application for inspecting and analysing the contents of music audio files, combining powerful waveform and spectral visualisation tools with automated feature extraction plugins and annotation capabilities.

Changes in Sonic Visualiser v1.6

  • 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.

Sonic Visualiser updated to v1.5

Sonic Visualiser

Chris Cannam has released version 1.5 of Sonic Visualiser, an application for inspecting and analysing the contents of music audio files.

This release has a few new features and a substantial number of bug fixes over the previous version 1.4. Also, the binary packages for this release have been built with Qt 4.5 instead of 4.4, offering better performance and platform integration.

Changes in Sonic Visualiser v1.5

  • 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.

Sonic Visualiser is available as freeware (GNU license) for Linux, Mac and Windows.

Chris Cannam updates Sonic Visualiser to v1.4

Sonic Visualiser

Chris Cannam has released version 1.4 of Sonic Visualiser, an application for inspecting and analysing the contents of music audio files.

It combines powerful waveform and spectral visualisation tools with automated feature extraction plugins and annotation capabilities.

Changes in Sonic Visualiser v1.4

  • SV now has a Region layer type, used for display of features with durations (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.
  • You can search for transforms by text in the new “Find a Transform” dialog.
  • 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.
  • Several crashes and other bugs have been fixed.

Sonic Visualiser is available as freeware (GNU license) for Linux, Mac and Windows.
