Vamp is a plugin format developed by Chris Cannam (author of Rosegarden and Sonic Visualiser) for viewing and analysing the descriptive contents of music audio files. Typical things that a Vamp plugin might calculate include the locations of moments such as note onset times, visual representations of the audio such as histograms, or curve data such as power or fundamental frequency.

Vamp can process selected audio and produce a label track with particular parts annotated with labels, based on various criteria.

Current plugins include: to be added

Plugin directories

Currently Audacity only loads plugins from the standard directories defined by the Vamp SDK, not any of the Audacity-specific directories. These are:

  • Any directories listed in the VAMP_PATH environment variable (all platforms)
  • On Windows, %%PROGRAMFILES%%\Vamp Plugins (i.e. a directory named "Vamp Plugins" within the system Program Files directory, however localised and on whatever drive is relevant to this install of Windows)
  • On Mac OS X, $HOME/Library/Audio/Plug-Ins/Vamp (user plugins) and /Library/Audio/Plug-Ins/Vamp (system-wide plugins)
  • On anything else but mainly Linux, $HOME/vamp, $HOME/.vamp (user plug-ins) and /usr/local/lib/vamp, /usr/lib/vamp (system-wide plugins).
