Hey,
I am writing the sound data from the mixer to a file of caf file
here is the asbd for caf
anASBD.mFormatID = kAudioFormatLinearPCM;
anASBD.mFormatFlags = kAudioFormatFlagIsSignedInteger |
kAudioFormatFlagIsBigEndian | kAudioFormatFlagIsPacked;
anASBD.mSampleRate = 44100;
anASBD.mChannelsPerFrame = 2;
anASBD.mFramesPerPacket = 1;
anASBD.mBytesPerPacket=anASBD.mChannelsPerFrame * sizeof (SInt16);
anASBD.mBytesPerFrame =anASBD.mChannelsPerFrame * sizeof (SInt16);
anASBD.mBitsPerChannel = 16;
this part is working fine.But Now I need to write to a 'wav' file instead for caf.
I tried all possible combination but failed every time.
Can anyone help me with the correct asbd for WAV file.
Thank you
Regards,
Nambiar
