ASIO 应用层函数分类大全

初始化/终止

ASIOError ASIOInit(ASIODriverInfo *info);
ASIOError ASIOExit(void);

开始、停止

ASIOError ASIOStart(void);
ASIOError ASIOStop(void);

查询方法和抽样率

ASIOError ASIOGetChannels(long *numInputChannels, long *numOutputChannels);
ASIOError ASIOGetLatencies(long *inputLatency, long *outputLatency);
ASIOError ASIOGetBufferSize(long *minSize, long *maxSize, long *preferredSize, long
*granularity);
ASIOError ASIOCanSampleRate(ASIOSampleRate sampleRate);
ASIOError ASIOGetSampleRate(ASIOSampleRate *currentRate);
ASIOError ASIOSetSampleRate(ASIOSampleRate sampleRate);
ASIOError ASIOGetClockSources(ASIOClockSource *clocks, long *numSources);
ASIOError ASIOSetClockSource(long reference);
ASIOError ASIOGetSamplePosition (ASIOSamples *sPos, ASIOTimeStamp *tStamp);
ASIOError ASIOGetChannelInfo(ASIOChannelInfo *info);

缓冲区制备

ASIOError ASIOCreateBuffers(ASIOBufferInfo *bufferInfos, long numChannels, long bufferSize,
ASIOCallbacks *callbacks);
ASIOError ASIODisposeBuffers(void);
ASIOError ASIOOutputReady(void);

其它

ASIOError ASIOControlPanel(void);
ASIOError ASIOFuture(long selector, void *params);

回调函数

void (*bufferSwitch) (long doubleBufferIndex, ASIOBool directProcess);
ASIOTime* (*bufferSwitchTimeInfo) (ASIOTime* params, long doubleBufferIndex, ASIOBool
directProcess);
void (*sampleRateDidChange) (ASIOSampleRate sRate);
long (*asioMessage) (long selector, long value, void* message, double* opt);
