| 2014-11-07 | Move xtract inside "include" directory | Jamie Bullock | |
| 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 | |
| 2008-03-26 | - Fixed build fail if --enable-fft not specified | Jamie Bullock | |
| - Fixed doxygen build so that it includes libxtract.h - Doxygen tweaks | |||
| 2008-02-15 | 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 | |||
| 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). | |||
| 2007-08-20 | Minor mods and typos corrections that were lurking uncommitted | 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 | |
| nyquist/DC inclusion. Added new boolean argument 'withDC' to select whether the DC component is required in the output | |||
| 2007-02-12 | Various minor fixes | Jamie Bullock | |
| 2007-01-29 | Added namespacing to enumerations and defines. Made most macros private. | Jamie Bullock | |

| 2007-01-11 | Fleshed out function descriptors. | Jamie Bullock | |
| 2007-01-10 | Rationalised spectral data format. Added spectral_mean et al | 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. | |||
| 2006-12-20 | Added new features: sum, highest_value, crest and noisiness | Jamie Bullock | |
| 2006-12-15 | Numerous fixes and enhancements, see ChangeLog. | Jamie Bullock | |
