Re: Best way to play samples on *both* 8580 and 6581 From: KuoH Reply to: KuoH@aol.com Date: Wed, 30 Sep 1998 10:34:30 -0500 Organization: Air Warrior References: <6uodtb$q60@chronicle.concentric.net> <6utglj$lba@journal.concentric.net> I thought that PCM was the method of representing the amplitude of an analog wave at regular intervals of time through the use of a series of discrete pulses (bits) or group of pulses (nibble, byte, word, etc..) And as Cameron pointed out, it could be anywhere from 1 bit to as high as the equipment can handle, the only difference would be in the resolution of the PCM data. Even shoving it into the SID 4 bits at a time would be considered PCM, provided that the data was encoded at 4 bit resolution to begin with. Packing them into bytes and using RS232 to move them really has nothing to do with PCM encoding, it's just storing or transferring the data more efficiently.
