The MATLAB implementation of the Chroma Toolbox (by Ewert and Müller) provides the following audio features:
|*Name*|*Description*|*Process*|
|Pitch|Semitone pitch spectrogram|88-bin elliptic filter bank, short-time energy summation|
|CP|Chroma|Pitch -> octave overlap -> various norm options|
|CLP|Chroma (log)|Pitch -> log compression -> octave overlap -> various norm options|
|CENS|Chroma energy-normalised statistics|Pitch -> octave overlap -> L1 norm -> quantize -> smooth and downsample -> L2 norm|
|CRP|(somewhat) Timbre-invariant chroma|Pitch -> log compression -> octave overlap -> cepstral reduction -> various norm options|
