Detailed Description

Logic to detemine the mime type from the content. By default the following mime types are supported (audio/aac, audio/mpeg, audio/vnd.wave, audio/ogg). You can register your own custom detection logic to cover additional file types.

Please not that the distinction between mp3 and aac is difficult and might fail is some cases
