I am working on a map + audio app, and I had been using Matt's but the added functionality here is great. I do have a question, say I wanted to have the user be able to navigate away from the nib, and control the audio from another nib. I am sort of a noob, but I don't know how to access the streamer controls for the currently playing audio from another nib. Not asking for code, but any ideas on direction would be helpful. Thanks!

All I can do is point you in the (hopefully) right direction. For example, if you kAQBufSize to something small, like 256, you will see things start to work a little better (although that is not necessarily the solution). The other place to look is handleReadFromStream where we handle kCFStreamEventEndEncountered. Somehow in there you need to add logic to start playback if playback was never started. Hopefully this gets you a little further. Please post any solution you come up with here.

Try same url as above with test2.mp3, test3.mp3, test4.mp3, test5.mp3, test6.mp3. Since they are all very short and most all of the others I would be working with also would be very short, your assessment of reaching eof before filling the buffers seems reasonable. Thanks again!

The problem with http://www.wally-young.com/test.mp3 is that it is really short and we hit the end of the file before we have filled any buffers (at least that's what it looks like at a quick glance). However, this seems to be different from your overall problem so testing with this MP3 doesn't do much good. Hi Wally, do you have MP3s I can test with?

I'm trying to get something to play smaller mp3's due to bandwidth contraints (and at&t's sucky data network!). I'm trying to keep the mp3s under 10k size to play in my app. Since the existing mp3's I have (about 1000) are all recorded at 48kBPS/16Hz they're nice and small. Any other suggestions/ideas? Sorry for the newbie questions, just trying to incorporate your and Matt's excellent work somehow w/o having to resort to larger mp3s. Thanks!
