Sonic Visualiser is 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.

Version 1.4 of Sonic Visualiser is now available.

http://www.sonicvisualiser.org/

This is a feature release, containing several new features and a
number of bug fixes over the previous 1.3 release. For more details,
please read the release notes at

https://sourceforge.net/project/shownotes.php?release_id=646456

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, slow down playback while retaining display synchronisation,
and show the ongoing alignment in time between multiple recordings of
a piece with different timings.

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, 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 are available. There is
also a comprehensive SDK for use by developers of Vamp plugins and
hosts. For more information about Vamp plugins, please see:

Sonic Visualiser was developed at the Centre for Digital Music, Queen
Mary, University of London:

Ongoing work on Sonic Visualiser and audio feature representation in
the semantic web is carried out as part of the OMRAS2 project funded
by the EPSRC. See
