Sonic Visualiser

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

Sonic Visualiser small screenshot

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).
