Just like an audio effects plugin (such as a VST), a Vamp plugin is a binary module that can be loaded up by a host application and fed audio data.

Typical things that a Vamp plugin might calculate include the locations of moments such as note onset times, visualisable representations of the audio such as spectrograms, or curve data such as power or fundamental frequency.
