Version 1.2 of Sonic Visualiser, an application for viewing and
analysing the contents of music audio files, is now available.
This is a significant feature release, containing a number of new
features over the previous release including a handy audio alignment
capability. For more details, please read the release notes at
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

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,
structural segmentation, timbral similarity, audio alignment
calculation and a large number of low-level spectral features.  There
is also a comprehensive SDK for use by developers of Vamp plugins and
hosts.  For more information about Vamp plugins, please see:
