我有一个基于音频单元的Objective-C音频应用程序,我的问题是当我播放声音然后停止播放另一个声音时,我听到第一个声音中的最后一个缓冲区。我想我应该只是释放ioData或其他东西,但我所有的尝试都失败了。删除从内存中播放的最后一个缓冲区
static OSStatus playbackCallback(void *inRefCon, AudioUnitRenderActionFlags *ioActionFlags, const AudioTimeStamp *inTimeStamp, UInt32 inBusNumber, UInt32 inNumberFrames, AudioBufferList *ioData)
{
RemoteIOPlayer *remoteIOplayer = (__bridge RemoteIOPlayer *)inRefCon;
for (int i = 0 ; i < ioData->mNumberBuffers; i++)
{
AudioBuffer buffer = ioData->mBuffers[i];
UInt32 *frameBuffer = buffer.mData;
for (int j = 0; j < inNumberFrames; j++)
{
frameBuffer[j]= [[remoteIOplayer inMemoryAudioFile] getNextPacket:inBusNumber];
}
}
return noErr;
}
请帮忙:)谢谢。
