age author description
Thu, 27 Dec 2007 17:51:07 +0000 Jamie Bullock - Added extra argument to xtract_spectrum to give the option of normalising the magnitude/power coeffificients
Mon, 24 Dec 2007 13:21:13 +0000 Jamie Bullock - Fixes to descriptors.c where no break statement was given for certain cases is switch conditionals
Tue, 16 Oct 2007 09:37:06 +0000 Jamie Bullock Fix for 'multiple symbol definitions' vs 'symbol not defined' dilemna. I 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...)
Sat, 06 Oct 2007 16:36:00 +0000 Jamie Bullock Removed fftw_plan from xtraction functions. Created new init function 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).
Wed, 03 Oct 2007 13:43:16 +0000 Dan Stowell Dan Stowell: Removed strange "zeroing" part of xtract_mfcc() which was 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!
Mon, 03 Sep 2007 14:31:58 +0000 Jamie Bullock Checked ANSI C89 compliance (basically a few ifndefs for the C99 math functions: powf, roundf etc). Added a few PD examples/tests.
