Hey Janina,
ecalength from the Ecatools[1] can do some, but mostly fails on ogg. I'm not sure how accurate it works on MP3s. Mplayer1 tends to get it wrong, but supports all the rest in MP3 very well. So caution! Length info is easily extracted.
sndfile-info[1] can do anything but MP3.sndinfo[3] also uses libsndfile and comes with csound. It also lacks MP3 support. Also easily parsable with awk.
A simple check on extensions can help in a shell script to process all but MP3 with the sndfile based tools. No idea on output format.
