To play them back, you'll need a decoder chip - I don't think that a PIC, or even a high-speed SX, is fast enough and has enough code space to do that kind of decoding. Check out the STA013 from ST Microelectronics, or the MAS3507D from Micronas Intermetall (sp?) - www.intermetall.de -Randy Glenn E-Mail: PICxpert@yahoo.com Web: http://i.am/PICxpert Currently wondering why I can't get in to Safe Mode - where's a Mac when you need it? -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Mark Skeels Sent: Friday, February 04, 2000 9:18 AM To: PICLIST@MITVMA.MIT.EDU Subject: [PICLIST] [OT]MP3 files Hi, all. Can anyone point me to some resources concerning MP3 files? I want to play them back, hopefully at a higher rate of speed than they were recorded at... :-) Mark __________________________________________________ Do You Yahoo!?
