On a hunch, I tried writing a 'caf' file, and passing a nil settings dictionary to the AVAudioFile constructor and this works for writing from a tap block.

So, it looks like I have either a misunderstanding of how to properly specify a non-caf file for AVAudioFile, or there's a bug. Before I file a radar, I would like to try one more time and see if anyone has been successful in creating an AVAudioFile of AIFF or WAV type.

best,

Greg

Hello all,

I've re-watched the relevant talks and re-read the headers and docs, but for the life of me I can't get an AVAudioFile from an AVAudioNode tap block that's playable. I'm trying to create an AIFF file, but haven't had success with any file-type. Bytes are written, no error, but the file isn't recognized as a valid AIFF by any media player.

Here's the code:

And here's some more details of variations on that code which I've tried:

Thanks for any help -- been stuck at this basic first step with AVAudioEngine for a while now. On the surface it looks like such a nice Swift-ready API compared to ExtAudioFile (with which I have experience), but so far I'm striking out.

Greg
