| 6 | 1 | Chris Cannam | |Pitch|Semitone pitch spectrogram|88-bin elliptic filter bank, short-time energy summation| |
| 7 | 2 | Chris Cannam | |CP|Chroma|Pitch -> octave overlap -> various norm options| |
| 8 | 2 | Chris Cannam | |CLP|Chroma (log)|Pitch -> log compression -> octave overlap -> various norm options| |
| 9 | 2 | Chris Cannam | |CENS|Chroma energy-normalised statistics|Pitch -> octave overlap -> L1 norm -> quantize -> smooth and downsample -> L2 norm| |
| 10 | 1 | Chris Cannam | |CRP|(somewhat) Timbre-invariant chroma|Pitch -> log compression -> octave overlap -> cepstral reduction -> various norm options| |

| 12 | 4 | Chris Cannam | The MATLAB code makes various things configurable or optional that are not mentioned in the brief documentation, such as making log compression optional in the CRP features, and supporting a smooth-and-downsample option for chroma and CRP. |
