Anyone out there tried tapping into their CD player and tee-ing the digital encoding into their home PC? Wonder if there's any way to get CD internals to generate something RS-232-like enough to be read into the COMM port that most PC's provide. Might be fun. If the PC can keep up with the bits at playing speeds, you might be able to graphically display the sound. Alternatively, has anyone tried buying a CD player and taking it into the computer lab? I understand that the CD player clones that move bits from optical disks into your Microvax (or whatever) use some of the bits for ECC, so they can't play standard audio CD disks. Wonder if that's true, and if so, overrideable somehow. -- -- Jon Krueger UUCP: ...seismo!rochester!ur-tut!tuba BITNET: TUBA@UORDBV USMAIL: University of Rochester Taylor Hall Rocheseter, NY 14627 (716) 275-2811

A certain company that I once visited (I am not sure if this is public info yet so I won't say who) has a system that reads the catalog from the disk and into an Apple 2e which is then used for controlling >= 1 CD for (e.g.) a disk jockey. I don't remember if the actual name of the song is recorded digitally on the disk, but the system would let you choose a song, it would tell you what disk to insert, and make sure it was the right one before playing the song. Pretty neat!! Paul Guthrie

The real question is, is there anything on the disk that's interesting enough to be fed into your PC? Most of the disks I have don't even bother to use the index marks, so why should I find anything interesting in the data fields? Phil

Let's see... 44100 * 16 * 2 gives 1.4112 million bits per second going into your home PC. That must be *some* RS-232 port you've got! What sort of algorithm are you planning on using?
