Although I think I got rid of - all the major bugs and I don't expect the API to change anymore, there - may be something I've missed. So use with caution. - - This algorithm is based on this original resampling algorithm: - Smith, Julius O. Digital Audio Resampling Home Page - Center for Computer Research in Music and Acoustics (CCRMA), - Stanford University, 2007. - Web published at http://www-ccrma.stanford.edu/~jos/resample/. - - There is one main difference, though. This resampler uses cubic - interpolation instead of linear interpolation in the above paper. This - makes the table much smaller and makes it possible to compute that table - on a per-stream basis. In turn, being able to tweak the table for each - stream makes it possible to both reduce complexity on simple ratios - (e.g. 2/3), and get rid of the rounding operations in the inner loop. - The latter both reduces CPU time and makes the algorithm more SIMD-friendly. -*/ - -#ifdef HAVE_CONFIG_H -#include "config.h" -#endif - -#ifdef OUTSIDE_SPEEX -#include <stdlib.h> -static void *speex_alloc (int size) {return calloc(size,1);} -static void *speex_realloc (void *ptr, int size) {return realloc(ptr, size);} -static void speex_free (void *ptr) {free(ptr);} -#include "speex_resampler.h" -#include "arch.h" -#else /* OUTSIDE_SPEEX */ - -#include "speex/speex_resampler.h" -#include "arch.h" -#include "os_support.h" -#endif /* OUTSIDE_SPEEX */ - -#include "stack_alloc.h" -#include <math.h> - -#ifndef M_PI -#define M_PI 3.14159263 -#endif - -#ifdef FIXED_POINT -#define WORD2INT(x) ((x) < -32767 ? -32768 : ((x) > 32766 ? 32767 : (x))) -#else -#define WORD2INT(x) ((x) < -32767.5f ? -32768 : ((x) > 32766.5f ? 32767 : floor(.5+(x)))) -#endif - -#define IMAX(a,b) ((a) > (b) ?
