How to access mp3 bitrate info in a shell script?
 

I have a large collection of mp3 files and they are encoded at various bitrates. I want to sort them into different directory hierarchies based on the bitrate. How can I access the bitrate info from a shell script so that I can do this?

Thanks in advance.

You can fairly easily just filter the output of a playback program of some sort.

For example, mplayer. If you try the command:

it should do what you want. Incidentally, it will work for any audio file that mplayer can play, not just mp3.

And if you find mplayer a wee bit to bulky for just that if you haven't installed it there's always one-purpose tools on Freshmeat and Sourceforge like for instance mp3info.

Thanks a million. That helps.
