That's exactly the way I did, and it worked for an AAC stereo stream, but when I try with an AAC multichannel stream, it seems that the Audio Converter doesn't support it. I can't find any precise information about multichannel decoding support, that's the reason of my question, maybe there's another format which is supported. Anybody knows ?

In theory, anything supported by Audio File Stream Services (like a Shoutcast stream, or um, Shoutcast…) should do.  I think your client would:

	1. Get callbacks from Audio File Stream Services when packets are received
	2. Use Audio Converter to convert those packets to LPCM
	3. Do whatever manipulations you need
	4. Provide the modified samples to an Audio Queue, I/O Audio Unit, or OpenAL source for play-out

Juggling the buffers between steps 3 and 4 might be the hard part, actually.

Hi all,

I need to stream (from my server) a multichannel audio stream that can be decoded by iOs. I also need to manipulate the raw PCM data after decoding in my iOs application. Is there any stream format that allows this ?
