On the hardware side, I think delta-sigma ADCs [1] might solve the same problem. They only sample 1-bit at a time, but they do so at a much faster rate than conventional ADCs. I'm a bit out of my scope here, but I think the concept is really cool. [1] https://en.wikipedia.org/wiki/Delta-sigma_modulation https://en.wikipedia.org/wiki/Delta-sigma_modulation
