Intersample Clipping - A Problem with Most Digital Playback Systems?

"Intersample clipping is the biggest problem with PCM systems." - John Siau

Oversampled sigma-delta D/A converters and fixed-point sample rate converters can add significant amounts of distortion when playing CD-format recordings. This distortion is caused by intersample musical peaks that overload our digital playback systems. These overloads often occur many times per second, even in a well-recorded track. This distortion can reach high amplitudes, and it can easily be measured, but it is completely invisible to traditional audio measurements. This distortion can easily be eliminated from our playback hardware, but most of the audio industry has failed to recognize this issue. Intersample clipping may be the single most audible defect in fixed-point PCM playback systems. It is the elephant in the room.

We need to change the way we build and test our digital playback systems.
