| 2013-01-09 | switched from single to double precision througout. closes #9 | Jamie Bullock | |
| 2013-01-07 | changed license from GPL to MIT. closes #6 | Jamie Bullock | |
| 2013-01-07 | added Ooura implementation to repository | Jamie Bullock | |
| 2011-03-30 | - reimplemented xtract_spectral_variance() xtract_spectral_skewness() and ↵ | Jamie Bullock | |
| xtract_spectral_kurtosis() using correct maths - removed xtract_spectral_average_deviation() | |||
| 2008-02-16 | - Added to pd example the ability to differentiate between different | Jamie Bullock | |
| 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 | |||
| 2008-02-15 | Added new extraction function: xtract_subbands() | Jamie Bullock | |
| 2008-02-15 | - Fixed bugs in xtract_flatness(), or at least added necessary | Jamie Bullock | |
| documentation and error checking to avoid problems - Added xtract_is_denormal() helper function and XTRACT_DENORMAL_FOUND return code - Replaced all instances of log, sqrt, exp etc. with respective floating point counterparts (logf etc.) - Added check for architecture endianness to configure script - Bug fix to PD example, now no longer crashes if no arguments are given - Minor documentation updates | |||
| 2008-01-01 | - Improvements to SWIG bindings generation script | Jamie Bullock | |
| - Fixed omission in xtract_bark_coefficients that was causing the output to be complete b/s! This fixed bark_coeffs and loudness feature which depends on it - Changes to descriptor API: added is_delta and id. id corresponds to value in xtract_features_ enum and is useful for programmatic conversions between id and name string. | |||
| 2007-12-29 | - PD example brought in line with new delta features and subframe function | Jamie Bullock | |
| - subframe-test.pd added - fix to a_blockswap~.pd | |||

| 2007-12-27 | - Added extra argument to xtract_spectrum to give the option of normalising ↵ | Jamie Bullock | |
| the magnitude/power coeffificients - Removed duplicate code block (argc assignment) from descriptors.c - Added some extra documentation to libxtract.h | |||
| 2007-12-24 | - Fixes to descriptors.c where no break statement was given for certain ↵ | Jamie Bullock | |
| cases is switch conditionals - Added LPC and LPCC extraction functions. LPC implements Durbin method as described in Rabiner and Juang and implemented in Dr. Dobbs 1994 edition by Jutta Degener | |||
