sonic-visualiser

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

Load audio files in various formats 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

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 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
