#include <nitro/snd.h>
void SND_SetPlayerTempoRatio( int playerNo, int ratio );
Changes the tempo of the sequence being played by the Player specified by playerNo
.
The original tempo is multiplied by ratio
/256 to get the final tempo value. (The value does not accumulate each time function gets called.)
This function is an ARM7 reserved function. After this function is called, processing occurs only after the command is issued with the SND_FlushCommand
function.
When it is necessary to synchronize something with the completion of the process, first use SND_GetCurrentCommandTag
to obtain the command tag immediately after calling this function. After the command is issued, use the command tag and call either the SND_IsFinishedCommandTag
or SND_WaitForCommandProc
function to confirm that the process has finished or to wait for it to complete.
SND_FlushCommand, SND_GetCurrentCommandTag, SND_IsFinishedCommandTag, SND_WaitForCommandProc
