A C++ Vamp plugin providing an efficient causal implementation of pitch-chroma audio features approaching timbre invariance, after the paper "Towards timbre-invariant audio features for harmony-based music" by Meinard Müller and Sebastian Ewert.
This plugin is intended to provide features extracted from a music audio signal, containing a reduction of the pitch and harmonic content of the audio which is relatively stable in the presence of timbral differences and local variations such as vibrato.
