Stereo reverse delay with feedback.
Illustrating another bizarre twist on the use of a simple digital delay as an audio effect. The input is reversed and added to
itself. The length of the reverse buffer corresponds to the delay length. The IIR filter is used to smooth the discontinuities
between successive flipped buffers. The effect is enhanced by feeding back the output of the filtered flipped signal back
into its own input.
Experiment with the delay and mixer settings to explore the interesting behaviour of this strange combination.
Widen the stereo field by adusting the left delay to be different from the right.
