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 2.5 of Sonic Visualiser is now available. This is primarily
a bugfix release, though it also adds a potentially-useful "unit
conversion" dialog. http://www.sonicvisualiser.org/
