[linux-audio-dev] Length of a soundfile in a script

I thought sox might be able to do it but I don't see it if it's there. I want to know how long (in time) an audio file is. Preferably output the number of seconds or some fraction thereof to stdout, and preferably can handle a large variety of sound types like sox (but if not, I can use sox). I know I could use sox to output raw and get the size of the resulting file and do a little arithmetic, but that would be silly if there's a utility for doing this sort of thing. Why? I have my computer as an answering machine, and don't want to be bothered with hangups (very short messages). BTW, an answering machine is great fun to mess with all sorts of audio things, especially the beeps. :-) -- .O.
