Wrote a small (and very messy) python 2.7 script for anyone interested: http://pastebin.com/e9iJWLiD Dependencies: sox, lame, mp3wrap in your PATH The script works very well and makes use of all 8 cores on my system for very fast MP3 encoding. I'm sure it can be applied to other formats/options if you mess around with your encoder executable and its settings. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
