Sonic Visualiser is an application for viewing and analysing the contents of music audio files.
The aim of Sonic Visualiser is to be the program you reach for when you find a musical recording you want to study rather than simply hear.
As well as a number of features designed to make exploring audio data as revealing and fun as possible, Sonic Visualiser also has powerful annotation capabilities to help you to describe what you find, and the ability to run automated annotation and analysis plugins in the new Vamp analysis plugin format.
Sonic Visualiser is Free Software, distributed under the GNU General Public License and available for Linux, Mac OS X, and Windows. It was developed at the Centre for Digital Music at Queen Mary, University of London, by Chris Cannam.
