Sonic Visualizer

Sonic Visualizer, a free application designed to make exploring audio data as fun as possible, has been updated.

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.

Sonic Visualiser has powerful annotation capabilities to help you to describe what you find, and the ability to run automated annotation and analysis plugins in the Vamp analysis plugin format – as well as applying standard audio effects.

Sonic Visualiser is Free Software, distributed under the GNU General Public License and available for Linux, OS/X, and Windows. It was developed at the Centre for Digital Music at Queen Mary, University of London, by Chris Cannam (of Rosegarden, Studio to Go!, DSSI etc). Read more…

Version 1.0 of Sonic Visualiser, an application for viewing and analysing the contents of music audio files, is now available.

Sonic Visualiser contains advanced waveform and spectrogram viewers, as well as editors for many sorts of audio annotations. Besides visualisation, it can make and play selections based on the locations of automatically detected features, seamlessly loop playback of single or multiple noncontiguous regions, synthesise annotations for playback, and slow down playback while retaining display synchronisation.

Sonic Visualiser supports the Vamp plugin API for plugins that extract descriptive or analytical data from audio. Vamp plugins for onset, pitch and note detection and tempo tracking using the Aubio library are available, as well as further plugins for tempo tracking, chromagram analysis, constant-Q spectrogram, spectral centroid, power curve, key estimation, tonal change detection, harmonic spectrogram, and a large number of low-level spectral features. There is also a comprehensive SDK for use by developers of Vamp plugins and hosts.

Sonic Visualiser is Free Software distributed under the GNU General Public License. The 1.0 release is available now in source code form or as binaries for Linux, OS/X, and Windows.
