Announcing Sonic Visualiser, an application for viewing and analysing
the contents of music audio files.
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 also introduces the Vamp plugin API, for plugins that
extract descriptive or analytical data from audio. Vamp plugins for
onset, pitch and note detection using the Aubio library are available,
as well as plugins for tempo tracking, chromagram analysis, constant-Q
spectrogram, spectral centroid, power curve and tonal change
detection. 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 0.9 release is available now in source code form
or as binaries for Linux, OS/X, and Windows.
