2006-12-15 Jamie Bullock * version 0.3.4 * Changed xtract_lowest_match(), to xtract_lowest(). It just returns the lowest non-zero component in the input array, between two bounds * qualified int *data, int N, and void *argv as const, thus insuring that they won't be modified by the called function. * added facilities for some functions to operate on copies of input data instead of modifying it. This will need to be optimised at some point maybe. * Added arguments to spectral flatness to allow for control over input band and pre-scaling * Fixed confusing xtract_init_mfcc() parameter order * Added new xtractor xtract_failsafe_f0 2006-12-12 Jamie Bullock * version 0.3.3 * Fixed errors in skewnes, kurtosis, irregularity_k, irregularity_j, tristimulus_1, tristimulus_2, and tristimulus_3. * Tested the above * Changed rolloff so output is in Hz. This means that a second argument (samplerate) needs to be passed in as argv[1] 2006-12-11 Jamie Bullock * version 0.3.2 * changed xtract_inharmonicity so that it takes frequencies AND amplitudes of peaks from *data rather than via *argv. This is consistent with xtract_centroid and others, and it means the data can come directly from xtract_peaks * Improvements to pd example (fixed memory allocation bugs) 2006-12-10 Jamie Bullock * version 0.3.1 * Fixed xtract_init_mfcc (array entries zeroed out if not set) 2006-11-10 Jamie Bullock * version 0.3.0 * Corrected typos in scalar.c * Added -Wall to CFLAGS and corrected problems relating to warnings * Added xtract_harmonics and corresponding documentation 2006-11-10 Jamie Bullock * version 0.2.2 * Fixed 'bus error' crash on Mac OS X by adding 'extern' declarations to xtract and xtract_help_strings 2006-10-24 Jamie Bullock * version 0.2.1 * Fixed _xtract and _xtract_help_strings memory alloc bug * Added new macro _ 2006-10-18 Jamie Bullock * version 0.2.0 * added PD help files * added simple help system 2006-10-12 Jamie Bullock * version 0.1.2 * improved xtract_f0 * changed versioning scheme 2006-10-09 Jamie Bullock * Released version 0.11
