Abstract

A relatively simple circuit is described which delays audio signals in 5 μs steps from 0 μs to 4000 μs. Delays are programmed via twelve TTL-level data lines. The magnitude response is flat and the phase response is linear from DC to 5 kHz. The gain of the circuit is fixed and independent of the selected delay. Delays are accurate to within 1 μs of the programmed value. The device is a nice alternative to other methods which have diverse shortcomings.
