Thanks to self
OK i found the kExtAudioFileProperty_ClientDataFormat property, so i
got it to work.
ExtAudioFileSetProperty(audioFileID,
kExtAudioFileProperty_ClientDataFormat,
sizeof(AudioStreamBasicDescription), &thruFormat);

I am trying to create a ExtAudioFile with the format from the
AURemoteIO but i get fmt?
it's all based on the auriotouch sample.
UInt32 size = sizeof(hwSampleRate);
XThrowIfError
(AudioSessionGetProperty
(kAudioSessionProperty_CurrentHardwareSampleRate, &size,
&hwSampleRate), "couldn't get hw sample rate");
XThrowIfError(SetupRemoteIO( rioUnit, inputProc, thruFormat),
"couldn't setup remote i/o unit");
audioFormat.mSampleRate = hwSampleRate;
audioFormat.mFormatID = thruFormat.mFormatID;
audioFormat.mFormatFlags = thruFormat.mFormatFlags;
audioFormat.mFramesPerPacket = thruFormat.mFramesPerPacket;
audioFormat.mChannelsPerFrame = thruFormat.mChannelsPerFrame;
audioFormat.mBitsPerChannel = thruFormat.mBitsPerChannel;
audioFormat.mBytesPerPacket = thruFormat.mBytesPerPacket;
audioFormat.mBytesPerFrame = thruFormat.mBytesPerFrame;
OSStatus fileErr = ExtAudioFileCreateWithURL (
fileURL,
kAudioFileCAFType,
&audioFormat,
NULL,
kAudioFileFlags_EraseFile,
&audioFileID );
and this is the values of the asbd
.mSampleRate = 44100;
.mFormatID = lpcm;
.mFormatFlags = 0x2c2;
.mFramesPerPacket = 1;
.mChannelsPerFrame = 2;
.mBitsPerChannel = 32;
.mBytesPerPacket = 4;
.mBytesPerFrame = 4;
PS have anyone successfully changed the asbd format of the
AURemoteIO ?
