I record a weekly radio show with streamripper, which I have automated using cron. The result is a two hour mp3, which is fine, except that no player except VLC can read it's timebase. This can be easily fixed by running the mp3 file through the "mp3val" command line tool, but I can't figure out how to automate this. Namely I don't know how to get the name of the streamripper output file to use in the mp3val command line. I am sure there must be an easy way to do this, and any help would be appreciated.
