# Audio Toolbox Convert File

The ConvertFile application provides sample code for converting audio data using the two main conversion mechanisms in CoreAudio: the ExtAudioFile and AudioConverter API. The project contains two targets, one for conversion using ExtAudioFile, and one using AudioConverter. The application provides examples of how to read in a data file, process data input arguments, and provide those to the conversion APIs.
