Here's a not so complete wish list that I think would be nice: 1) Improvements to the frame checking logic? 2) crc16 checking/adding of the frame would also be nice since I am able to retrieve the 'protection bit' from the frame. 3) id3v2 support and analysis. Any additional requests, please send them to me at ericb@thedeepsky.com. Thanks for all the e-mails from you out there for how you are using mp3_check. I really enjoy hearing from you. KEEP THEM COMING!!! :) I would really like to get your testimonials of how you are using it. :) -Eric
