| 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 | |||
| 2008-01-02 | - Minor fix in xtract_lpc... or at least think it's a fix | Jamie Bullock | |
| 2008-01-02 | - Re-factoring in xtract_spectrum and fixed normalisation bug | Jamie Bullock | |
| - Fixed bug in xtract_lnorm | |||
| 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 | |||

| 2007-12-24 | - 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 | |||
| 2007-10-16 | Fix for 'multiple symbol definitions' vs 'symbol not defined' dilemna. I ↵ | Jamie Bullock | |
| think the solution is to wrap the globals in a struct, declare it in a header, and wrap with a definition guard, then define _once_ at library init time. (Sounds like a recipe for something...) | |||
| 2007-10-09 | Added missing extern storage class specifier to private globals | Jamie Bullock | |
| 2007-10-09 | Fixed bug in xtract_init_mfcc() - iteration to decide filter peak positions ↵ | Dan Stowell | |
| only filled in freq_bands+1 values, when it should fill in freq_bands+2 | |||
| 2007-10-08 | Committed missing files needed for new out-of-place fftw plan creation | Jamie Bullock | |
| 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). | |||
| 2007-10-03 | Dan Stowell: Removed strange "zeroing" part of xtract_mfcc() which was ↵ | Dan Stowell | |
| zeroing a load of elements despite the fact that they're ignored by the DCT process called next, and never used for anything. This was writing to an assumed large result array (same size as number of FFT bins) despite the fact that only a small number of MFCCs (typically less than 50) are required, therefore either wasting memory or writing to memory it shouldn't do! | |||
| 2007-10-03 | Minor modifications to MFCC init, mainly just code formatting | Dan Stowell | |
| 2007-09-24 | Made xtract_loudness() more permissive, so it doesn't crash if N > BARK_BANDS | Jamie Bullock | |
| 2007-09-06 | Java bindings (with simple test) now working. Unified Python and Java ↵ | Jamie Bullock | |
| bindings tests. | |||
| 2007-09-05 | Added java bindings. Everything seems to work OK, except test.java won't ↵ | Jamie Bullock | |
| compile. Some kind of path error, but I can't work out how to fix it. | |||
| 2007-09-04 | Added basic SWIG wrapper generator (use ./configure --enable-swig etc) | Jamie Bullock | |
| 2007-09-03 | Checked ANSI C89 compliance (basically a few ifndefs for the C99 math ↵ | Jamie Bullock | |
| functions: powf, roundf etc). Added a few PD examples/tests. | |||
