Sweep the bit depth from 1 to 12 while a looping arpeggio plays through a live quantizer: at 12 bits the noise is inaudible, by 4 bits there is a clear hiss, at 1–2 bits the melody is heavily distorted but still in tune. The plot shows the wave snapped to bucket centres and the rounding error left behind; a bypass button removes the quantizer for comparison.
The claim above is what this widget demonstrates. Disagree with it?
