Sonic Visualiser contains advanced waveform and spectrogram viewers, as well as editors for many sorts of audio annotations. Besides visualisation, it can make and play selections based on the locations of automatically detected features, seamlessly loop playback of single or multiple noncontiguous regions, synthesise annotations for playback, and slow down playback while retaining display synchronisation. Sonic
Visualiser also supports the Vamp plugin API for plugins that extract descriptive or analytical data from audio.
