AB  - A fundamental problem of digital dynamics processing is that distortion products are produced which alias below 20 kHz. An analysis of sine-wave clipping shows that a 5-MHz internal sampling rate is required to effectively attenuate aliasing components. A test signal consisting of a pair of closely spaced sinusoids that are slowly swept in frequency is suggested as a means of revealing aliasing distortion in typical digital audio systems. Many current digital audio products produce audible aliasing distortion when passing this test signal. It is suggested that there is a correlation between the amount of aliasing distortion produced in digital dynamics processors and their sonic qualities.
