Sonic Visualiser
Sonic Visualiser is
an application for inspecting and analysing the contents of music audio
files.
Sonic Visualiser combines powerful waveform and
spectral visualisation tools with
automated feature extraction plugins and annotation
capabilities. It also has powerful annotation capabilities to
help you to describe what you find, and the ability to run automated
annotation and analysis plugins in the Vamp analysis plugin format
– as
well as applying standard audio effects.
The aim of Sonic Visualiser is to be the first program you
reach for when want to study a musical recording rather than simply
listen to it.

Features include:
- 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
- Overlay annotations on top of one another with aligned
scales, and overlay annotations on top of waveform or spectrogram views
- View the same data at multiple time resolutions
simultaneously (for close-up and overview)
- Run feature-extraction plugins to calculate annotations
automatically, using algorithms such as beat trackers, pitch detectors
and so on
- Import annotation layers from various text file formats
- Import note data from MIDI files, view it alongside other
frequency scales, and play it with the original audio
- Play back the audio plus synthesised annotations, taking
care to synchronise playback with display
- Select areas of interest, optionally snapping to nearby
feature locations, and audition individual and comparative selections
in seamless loops
- Time-stretch playback, slowing right down or speeding up to
a tiny fraction or huge multiple of the original speed while retaining
a synchronised display
- Export audio regions and annotation layers to external files
