[linux-audio-dev] Sound file format detection?

Hi. My little time-compressing audio player yatm currently supports 3 different audio formats, ogg and speex via the xiph libraries, and mpeg via libmad. I currently just blindly try to launch the decoder for either ogg, speex or mp3 in series. SO if the first fails, I try the second, and so on. Which kinda works but is a bit ugly. I'd like to add flac support at some point, which would make this even more ugly. Additionally, libsndfile support wouldnt be that bad either, so, I am wondering, is there a reliable way to detect a audio streams file format just given some bits of the header? So that I could set the appropriate decoder algorithm based on that analysis? Or is there actually a library one step higher level than libsndfile which does generic audioformat to PCM? I guess not... -- CYa, Mario
