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
2007-10-06Removed 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).

2007-03-20Ammended xtract_mfcc() documentationJamie Bullock
2007-03-19Further updated xtract_spectrum() to hopefully fix fft iteration bug and ↵Jamie Bullock
