[mad-dev] test if file is mp3

[Erik Turner]

The best way that I've found to attempt to find a
synch pattern, decode the frame (which gives you
the frame length) and see if the next frame is a
valid frame (i.e. is valid synch).

This won't guarantee that the whole file is valid
but it does indicate that it contains at least one
(probably two) valid MP3 frames.

Hy list,
is there a good and fast way to test if a file actually is a mp3 file or
not?
My attempts with decoding some bytes at the beginning of the file do not
work...

Thanx for help.

Cheers,
Sebastian
