I was wondering if anyone personally, or if anyone knows of a web-site that provides information on how much music data/time can be put on an 80 minute CDR with different mp3 bit rates. For example, if I wanna convert music to an mp3 file at 192 kbit/s, how much music/data/time could I fit on an 80 minute CDR disc at this rate? Same thing for 256 and 320 kbit/s. I have some old American Top 40 4 LP sets that I would like to needle drop and then move to CDR using mp3, but I was wondering how much can I get onto an 80 minute CDR either using 192, 256 or 320 bit rates. Thanks!
