how to identify mp3 audio files with just noise in it

[Evuraan <evuraan@gmail.com>]

Greetings!

how to identify an mp3 file which has just static noise in it?

I want to identify & delete files which does not have any human
voice/musical element in it. I don't have the luxury of mp3tags to
use.

Just Noise: http://bit.ly/qkhBux
Not Noise:  http://bit.ly/oZmdLS (good file, the kind I want to retain)

is there something like jp2a out there for audio files to profile the
histogram of its contents?

hope this question makes sense.

Many thanks in advance!
