I'm attempting to use Audio Queue Services for the first time. After reading all the documentation and playing with some sample code, I think I understand the classes pretty well and have implemented my own playback and recording application without any problems.

I need to simultaneously record and play from the same buffer, but I'm having some significant difficulty writing to a file and reading from the file at the same time. I can get the file to be played back with no problem but only for the last written buffer before the playing started. I'm hoping it's possible to continue to playback the file for as long as it's being written to. Is this possible?

Thanks in advance!
