The Digital Delay

A digital delay is a very simple thing — it repeats signals after a pre-defined time.

Evolver’s digital delay is the same quality as Evolver’s A/D and D/A converters (16-bit, 48 KHz) and can provide up to 1 second of delay time.

Evolver’s delay sums both Left and Right channels to mono (L+R) for its input. Evolver’s delay output is fed back to both Left and Right channels equally, which places it in the center of the stereo field at all times.

The delay offers 3 “taps”. In this case, “tap” is a digital signal processing (DSP) term. Imagine the digital delay as a pipeline that is 1 second long. Evolver’s signal goes in one side of the pipe, and 1 second later, comes out the other side.

We can “tap into” the “pipeline” of delayed signal at 3 points. Each tap can be at the same place on the pipeline or the taps can be placed at different points on the pipeline.

Tap placement corresponds to a delay time — placing a tap near the start of the pipe produces a very short delay, while placing a tap at the very end would produce a delay of 1 second.

We can also control the amount of tapped signal.

Each of the 3 taps has a time parameter and a level parameter.

Time determines where the delay pipeline is “tapped”. The range of time values is divided into 3 sets of ranges (more about that in a moment).

Level simply determines how loud delayed signal is played — 0 is “not at all” and 100 is “as loud as the original”.
