Title: Reading packets from an audio file
hai,


when I use the functions,

AudioFileGetProperty(audioFileID, kAudioFilePropertyAudioDataPacketCount, &ioDataSize, &outPropertyData); and

AudioFileReadPackets(audioFileID, false,
                         &numByte, buffer->mPacketDescriptions, startingPacketNumber,
                         &numPacket, buffer->mAudioData);


I get different value when compared to the real packet number of the audiofile.

I work with .caf files .

and I am also little bit confused with  “ ioDataSize “ , the  third argument of the AudioFileGetProperty();
function.


thank you.
