Re: What's confusing to most people about this

Agree on mouthful and audience.

To recover the peak signal, the reconstruction math has to work quite hard, and requires samples around the peak of interest.

There will be a tradeoff between the window size and the ability to reconstruct the waveform beyond the simple DAC hold between samples.

I make the assumption that most CD outs are simple filtering of the staircase DAC output signal after the hold circuit.

I do like the thought of a digital brickwall filter, as that could easily include a large sample delay for better implimentation and reconstruction. My thinking has been only on analog filtering.

Cheers, John
