Sonic Visualiser

A program for viewing and analysing the contents of music audio files

Home page and downloads: http://sonicvisualiser.org/
Code project: https://code.soundsoftware.ac.uk/projects/sonic-visualiser

With Sonic Visualiser you can:

Load audio files in various formats (WAV/AIFF, plus Ogg and mp3 if compiled in) and view their waveforms
Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters
Annotate audio data by adding labelled time points and defining segments, point values and curves
Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on (see http://vamp-plugins.org/)
Import annotation data from various text formats and MIDI files
Play back the original audio with synthesised annotations, taking care to synchronise playback with the display position
Slow down and speed up playback and loop segments of interest, including seamless looping of complex non-contiguous areas
Export annotations and audio selections to external files.

Sonic Visualiser can also be controlled remotely using the Open Sound Control (OSC) protocol (if support is compiled in).
