So if you can accurately calculate that from some soundfiles, you might be in business. I haven't found the algorithm defined anywhere, but maybe these excerpts from the DiscID python module will serve as explanatory pseudocode. It's at http://cddb-py.sourceforge.net/ BUT... I'm not sure how "leadout" is extracted; that might scuttle your idea. # If called from the command line, will print out disc info in a # format identical to Robert Woodcock's 'cd-discid' program. def cddb_sum(n): ret = 0 while n > 0: ret = ret + (n % 10) n = n / 10 return ret def disc_id(device): (first, last) = cdrom.toc_header(device) track_frames = [] checksum = 0 for i in range(first, last + 1): (min, sec, frame) = cdrom.toc_entry(device, i) checksum = checksum + cddb_sum(min*60 + sec) track_frames.append(min*60*75 + sec*75 + frame) (min, sec, frame) = cdrom.leadout(device) track_frames.append(min*60*75 + sec*75 + frame) total_time = (track_frames[-1] / 75) - (track_frames[0] / 75) discid = ((checksum % 0xff) << 24 | total_time << 8 | last) -- Paul Winkler http://www.slinkp.com
