|
Set equalizer points to create new frequency bands.
__stdcall __declspec(dllimport) int zplay_SetEqualizerPoints(ZPLAY_HANDLE handle, int * pnFreqPoint, int nNumOfPoints);
|
Parameters |
Description |
|
ZPLAY_HANDLE handle |
ZPLAY handle. Get this handle with zplay_CreateZPlay. |
|
int * pnFreqPoint |
Array of integers specifying frequency points to divide whole frequency range into bands. You have frequency range from 0 Hz to SampleRate/2 Hz. You need to specify frequency points to divide this range into bands. One point will divide range into 2 bands, 2 points will divide range into 3 bands ... If this value is NULL, class will restore default bands. |
|
int nNumOfPoints |
Number of points in pnFreqPoint array. |
|
Return Values |
