AudioFileWritePackets data format

Subject: AudioFileWritePackets data format
From: Stephen Blinkhorn <email@hidden>

Hi,

I have a sound buffer in memory that I want to export as an audio file. The sound buffer contains raw 64 bit floating point data and I'd like to export that as a 24 bit AIFF.

Is it possible to use AudioFileWritePackets directly (specifying an AudioStreamPacketDescription) on the 64 bit float data to write to the AudioFile or must I convert the data to 24 bit first?

I'm thinking I can use AudioFileWritePackets to write any data to a file as long as it knows the source data format and the destination data format and it will automatically convert? Is that correct? I'm getting white noise in the exported files!

Thanks,
Stephen
