Delay

Background: Delay

A delay line makes a copy of the incoming audio, holds it in memory, then plays it back
after a predetermined time.
Long delays produce echoes, short delays can be used for doubling or slapback effects.
Very short delays can be used to produce resonant flanging and comb filter effects or
create monotone robotic-sounding effects (Hint: use feedback). Stereo signals are
summed together before entering a mono delay.
A feedback path recirculates the delayed audio back around through the delay line.
When creating echo effects, the feedback controls how many echoes will be produced.
With short delay settings, the feedback control acts as a resonance control, increasing the
amount of comb filtering produced by the delay line.
A Tone control in the feedback path cuts some of the high frequency energy each time
the audio goes through the delay line. This simulates the natural absorption of high
frequencies in a room and can also be used to simulate tape-based echo units.
The Wet/Dry mix controls how loud the echoes are in relation to the original signal.
This Delay is a true stereo delay line with completely independent left and right
channels right channels. This delay line features four different modes, which affect how
the signals are routed and cross coupled.

Discrete stereo

Use this mode when you want to preserve the stereo image of the delayed signals. You
can also create panning effects by setting one delay long and the other short.
Delay Mode:
Discrete stereo
The left and right
channels are kept
totally separate.
