iosinmemoryrecord

Example of recording and playing back audio data on iOS using an IO Audio Unit.

Overview

This is a reference project which is the result of a few weeks of learing about the audio recording capabilities of the iOS platform.

The project illustrates the following:

• simplistic use of the AudioUnit API, in particular the remote I/O unit
• interaction between Objective-C methods and C functions with ARC enabled
• a basic technique to solve the problem of displaying real-time information on the user interface
• setup and use of in-memory data buffers tailored towards capturing live audio data from the device
