Interesting question about the input. I call it "clock",
because it's applied to the clock input of the shift register.
As far as output goes, I use one bit into a low pass filter.
I don't know if there are advantages to using a DAC. What I
hear sounds like (white?) noise to me using one bit into an LPF.
