typedef void(* MxStreamCallback) (int16 *buffer, size_t samples) |
Type of callback functions for supplying PCM music.
A music decoder/renderer implements this function and installs it with MxSetMusicSource, which also returns the sample rate used.
buffer | Pointer to interleaved 2-channel signed 16 bit PCM data buffer, guaranteed to be 0-initialized. |
samples | number of samples that must be filled into buffer . |
void MxSetChannelVolume | ( | MixerChannel * | mc, |
uint | volume, | ||
float | pan | ||
) |
Set volume and pan parameters for a sound.
mc | MixerChannel to set |
volume | Volume level for sound, range is 0..16384 |
pan | Pan position for sound, range is 0..1 |
uint32 MxSetMusicSource | ( | MxStreamCallback | music_callback | ) |
Set source of PCM music.
music_callback | Function that will be called to fill sample buffers with music data. |
