I've spent some time in doing searching and nothing comes up, here as well as on the net, so I'm going to the best sources, human brains.
I'm working on a digital delay, and for a number of reasons I'd like to control operation with a PIC and do the ADDA and memory on the cheap. I'm having trouble finding converters that make this fairly simple. So do you have a pointer to:
- a sigma-delta mod/demod chip with a bitstream output that's not expensive?
- an audio CODEC with parallel outputs/inputs?
- an audio CODEC with serial word outputs that can eat its own output when fed back into its input?
Obviously I'm after quick and only-slightly-dirty delay here, and while I can do the interfacing between chips and memory, I'd like to keep the clot of logic down to minimal.
Any pointers?
