Human hearing beats sound’s uncertainty limit

Modern audio compression algorithms rely on observations about auditory perceptions. For instance, we know that a low-frequency tone can render a higher tone inaudible. This perception is used to save space by removing the tones we expect will be inaudible. But our expectations are complicated by the physics of waves and our models of how human audio perception works.
