The digital delay is a device that uses digital technology to store an audio signal and play it back. The digital delay has evolved from the tape echo, which had difficulty maintaining signal quality. Digital delays store the signal by means of digital sampling, a technique that samples the sound several thousand times a second and converts it into a binary code that is stored in the unit’s memory. The more memory available in a unit, the better is the frequency response and the longer the delay. The advantage of digital storage is that it turns the sound into numbers. Digital storage maintains excellent frequency response and provides options to modify the stored sound, including flanging, phasing, pitch change, echo, and chorus effects.
