Re: New presonus mixer




Actually one of the earliest digital studio delay lines (delta-lab) used one bit digital encoding (delta-modulation). A simple above/below comparator drives a 1 pole integrator up/down until the comparator changes the direction of the fixed slope. If the clock rate, which is the same thing as the data rate, is high enough these could sound very good (say 1 meg bit per second). They were notorious for sounding very bad when pushed to too low clock rate in an attempt to get longer delays (digital memory was very expensive in the old days). A distortion called slope overload occurred in the margin but this is too much information about an obsolete technology.
