Might have been me that said that about queues, and just in that they can work with encoded formats like MP3 and AAC, which is usually what you're receiving in a streaming scenario. With the tap stuff that they introduced a while back ― giving you a look at the decoded PCM right before it's played ― you kind of get the best of both worlds.
But that's for playing streams. In your case, it sounds like you're capturing, processing, and uploading. I think the recording queue might still work for you, but I don't recall if the tap works in the recording case (letting you apply effects to captured PCM before it's encoded to AAC by the queue); I think I messed with it once and ended up filing bug reports. Try it, I guess? Otherwise I guess you'd capture to audio units, do your processing there, encode to AAC with Audio Converter Services (please enjoy your time in hell), and upload. ―Chris Sent from my iPad > On May 14, 2015, at 5:55 AM, Mahboud Zabetian <[email protected]> wrote: > > Hi. > > I'm building a simple streaming system: I want to capture sound while doing > FLAC compression on n-packets at a time and uploading to a server in > real-time. > > I haven't used AudioQueues before, but have some experience with AudioUnits. > I seem to recall reading someplace (maybe in the Adamson/Avila book) that > AudioQueues are well-suited for streaming.
