Hi All,
I captured the audio using audioUnit.After rendering for sample rate conversion
I used AudioConverterConvertBuffer.It works good in Intel.But in PPC no
error.I got continous noice sound.
Waiting for your valuable advice,
Thanks in Advance,
Sheen
Code
========
fOutputFormat.mChannelsPerFrame = 1;
fOutputFormat.mFormatID = kAudioFormatLinearPCM;
fOutputFormat.mFormatFlags = kAudioFormatFlagsNativeFloatPacked;
fOutputFormat.mBitsPerChannel = 32;
fOutputFormat.mBytesPerFrame = 4;
fOutputFormat.mFramesPerPacket = 1;
fOutputFormat.mBytesPerPacket = 4;
stdFormat=fOutputFormat;
stdFormat.mSampleRate=44100.0;
err=AudioConverterNew(&fDeviceFormat,&stdFormat,&conv);
void convertSampleRate(UInt32 auSize,void* auData)
{
UInt32 outputDataSize,audioDataSize;
OSStatus status;
int
count=0;
tempData=realloc(tempData,auSize);
audioDataSize =auSize;
outputDataSize=audioDataSize;
UInt32 dataSize=sizeof(conv);
AudioConverterGetProperty(conv,kAudioConverterPropertyCalculateOutputBufferSize, &dataSize, &outputDataSize);
status = AudioConverterConvertBuffer(conv,auSize,auData,&outputDataSize, tempData);
bcopy(tempData,auData, audioDataSize);
}
