[LAU] Retrieving audio info from a video file

Hi all, This is slightly OT for the group, but I hope someone can tell me. I have thousands of large AVI files and I want a quick way to determine from the command line whether their audio is stereo, 5.1, etc. I've read about ffmpeg and haven't seen anything jumping out at me, and it's hard to pick the right search keywords to find relevant pages on Google. Anyone know a trick to get this info? Currently I can do it by right-clicking on the file and viewing its properties, but there *has* to be a better way...
