Sonic Visualiser is a free, open source, cross-platform desktop application for music audio visualisation, annotation, and analysis.

With Sonic Visualiser you can:

Load audio files in various formats (WAV/AIFF, Ogg, Opus, MP3 etc) 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 https://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).
