- Added to pd example the ability to differentiate between different
argv types (XTRACT_FLOAT, XTRACT_INT) and pass the correct data type
to the xtract[]() function
- Added xtract_flatness_db() details to descriptors.c
- Fixes to tonality and xtract_subbands descriptors
- Added Pd examples for 'subband mean' and tonality calculated using subbands
