How Long is a Sound [Without Using Quicktime]?

I don't have a good solution but here are some crazy ideas...

If these are all sounds you supply, you can write a script that times all the sounds in some folder (or stack) and creates a table.

If you know these all are the same bit rate and the same number of channels, and there is no compression in the format, then maybe you can estimate from the file length.  Tweak an offset to cover headers and trailers.

Maybe there are some command-line tools that can work with shell().  I quick search brought up names like mp3info, soxi, afinfo, mp3split, and sox.

Or, if you handle only a small number of sound formats, parse the files.
