Vamp is a plug-in 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 plug-in 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.

Plug-in directories

Currently Audacity only loads plug-ins 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 Plug-ins (i.e. a directory named "Vamp Plug-ins" 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 plug-ins) and /Library/Audio/Plug-Ins/Vamp (system-wide plug-ins)
  • On anything else but mainly Linux, $HOME/vamp, $HOME/.vamp (user plug-ins) and /usr/local/lib/vamp, /usr/lib/vamp (system-wide plug-ins).
Peter 11Jun15: ToDo-1 After 2.1.1 is released this will need updating for the new Manage Effects/Generators/Analyzers method of installing plug-ins.
