A friend e-mailed me today asking what I thought of the new Sound Devices MixPre series that has 32-bit conveters. I looked it up, and I see that AKM makes a few for audio (they've been around for instrumentation for a while, for very high resolution at low sample rates, like 5 samples/second). The noise specs for the chip don't look a whole lot better than what we've been used to seeing for the past few years.
Have I not been paying attention? I didn't think there was anything but noise beyond what you could resolve with 21 or 22 bits. Is this just "mine is longer than yours?" Or is high resolution low level noise better (subjectively) than no lo level noise at all?
