Hi Gary:
You are probably beyond me on this stuff so I might not be answering this question properly. I'm just using the stand-alone Teensy 3.2, no outboard Codecs or anything.? The 3.2 is fast enough to sample audio over an ADC pin and perform basic operations like filters and FFTs.? There's a DAC for output too.? Op amps are used to deal with offsets/scaling/etc.
