Program for viewing and analysing the contents of music audio files

Sonic Visualiser is a program for viewing and analysing the contents of music audio files.

It supports serveral audio file formats and displays their waveforms and spectograms in a straightforward way. The audio data can be annotated and played back featuring time streching. Furthermore it can be extended by third-party vamp plugins for feature extraction.
