MimeDetector Class Reference

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. More...

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
