Yes, I think that's the correct approach. My old script, written when I was new to FreeBSD (at v4.0), uses the unelegant "sox -r 44100 -c 2 -w -s $FILE.raw $FILE.cdr" to convert to the proper CD audio format which could also be used by burncd (deprecated?), but also by cdrdao and cdrecord with no additional conversion parameters. Thanks for the hint about lame --decode! -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
