Description

Demonstrates using Audio Queue offline render functionality and the AudioQueueOfflineRender API. The sample produces LPCM output buffers from an ALAC encoded source which are then written to a .caf file. The output.caf file is then played back confirming the offline functionality worked as expected. All the code demonstrating the Audio Queue is in a single file called aqofflinerender.cpp.
