出错原因：参数不全
初始状态：aqrs.mDataFormat.mFormatID = kAudioFormatLinearPCM; aqrs.mDataFormat.mSampleRate = 44100.0; aqrs.mDataFormat.mChannelsPerFrame = 1; aqrs.mDataFormat.mBitsPerChannel = 8 * sizeof(SInt16); aqrs.mDataFormat.mBytesPerPacket = aqrs.mDataFormat.mBytesPerFrame = aqrs.mDataFormat.mChannelsPerFrame * sizeof(SInt16); aqrs.mDataFormat.mFramesPerPacket = 1;
增加：
aqrs.mDataFormat.mFormatFlags = kLinearPCMFormatFlagIsSignedInteger |kLinearPCMFormatFlagIsPacked;
问题解决！
