| 2013-01-07 | added Ooura implementation to repository | Jamie Bullock | |
| 2012-03-29 | - fixed build-time bug. in some cases average_deviation was commented out ↵ | Jamie Bullock | |
| instead of spectral_average_deviation | |||
| 2011-03-30 | - reimplemented xtract_spectral_variance() xtract_spectral_skewness() and ↵ | Jamie Bullock | |
| xtract_spectral_kurtosis() using correct maths - removed xtract_spectral_average_deviation() | |||

| 2008-05-04 | Fixed bug in peak interpolation algorithm in xtract_peak_spectrum() | Jamie Bullock | |
| 2008-03-26 | - Fixed build fail if --enable-fft not specified | Jamie Bullock | |
| - Fixed doxygen build so that it includes libxtract.h - Doxygen tweaks | |||
| 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 | |||
| 2007-12-28 | - Added new helper functions: xtract_windowed() and ↵ | Jamie Bullock | |
| xtract_features_from_subframes() - Added windowing functions (window.c) | |||
| 2007-12-27 | Added l-norm/spectral flux | Jamie Bullock | |
| 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 | |||
| 2007-10-06 | Removed fftw_plan from xtraction functions. Created new init function ↵ | Jamie Bullock | |
| xtract_init_fft() for creating plans, which have global scope. Updated examples to reflect the change. New configure option: --with-fft_optimisation (0 = FFTW_ESTIMATE, 1 = FFTW_MEASURE, 2 = FFTW_PATIENT). | |||
| 2007-09-06 | Java bindings (with simple test) now working. Unified Python and Java ↵ | Jamie Bullock | |
| bindings tests. | |||
| 2007-08-20 | Minor mods and typos corrections that were lurking uncommitted | Jamie Bullock | |
| 2007-08-19 | Fixes for MSP example, and changed the fundamental estimators so that if ↵ | Jamie Bullock | |
| they don't get a samplerate 44100 is assumed (I'm not sure if this is a good idea!). | |||
| 2007-04-20 | Fixed autocorrelation_fft() it now gives comparable output to autocorrelation() | Jamie Bullock | |
| 2007-03-20 | Ammended xtract_mfcc() documentation | Jamie Bullock | |
| 2007-03-19 | Further updated xtract_spectrum() to hopefully fix fft iteration bug and ↵ | Jamie Bullock | |

| 2006-12-21 | Added xtract_slope() | Jamie Bullock | |
| 2006-12-21 | xtract_magnitude_spectrum() and xtract_peaks() share format of N/2 frequency ↵ | Jamie Bullock | |
| values and N/2 magnitude coefficients. 'Fixed' xtract_loudness() so that N=1 can be used for specific loudness. | |||
