The longest it could take is at 1X. Since an AudioCD is 74 minutes the longest this task will take is about 8 times 80 or 640 minutes or 10 hours 40 minutes for the entire set. If your rip speed is 2X then its 320 minutes or 5 hours 20 minute and for higher speed ripping, it almost linear.

How long should it take to rip an audio book from a CD using windows media 11? The book has like 8 CDs. Sorry for such a dumb question but it seems like it is taking hours. Thank you to anyone who can help me with this.
