| If you are just trying to decompress an audio file in memory, you can use the CoreAudio ExtendAudioFile API which does exactly that:

Trying to convert compressed audio file dynamically and populating array with PCM sample integer amplitudes for further evaluation. Following the steps in http://www.subfurther.com/blog/category/ipod/ - I am good up to the point of writing to file via assetWriterInput object. But why can't i grab the decompressed sample data before they are written into file? My hunch is that there is more going on behind the scenes with the assetWriter in terms of conversion.
Is AudioConverterFillComplexBuffer the correct approach to capture decompressed audio dynamically? Any examples are greatly appreciated.
