Do this:
#define TSF_IMPLEMENTATION
before you include this file in *one* C or C++ file to create the implementation.
// i.e. it should look like this:
#include ...
#include ...
#define TSF_IMPLEMENTATION
#include "tsf.h"
[OPTIONAL] #define TSF_NO_STDIO to remove stdio dependency
[OPTIONAL] #define TSF_MALLOC, TSF_REALLOC, and TSF_FREE to avoid stdlib.h
[OPTIONAL] #define TSF_MEMCPY, TSF_MEMSET to avoid string.h
[OPTIONAL] #define TSF_POW, TSF_POWF, TSF_EXPF, TSF_LOG, TSF_TAN, TSF_LOG10, TSF_SQRT to avoid math.h
NOT YET IMPLEMENTED
- Support for ChorusEffectsSend and ReverbEffectsSend generators
- Better low-pass filter without lowering performance too much
- Support for modulators
