LFO Delay is a general-purpose modulated delay line — the basis of flanging and chorus effects. Delay sets the base delay time (1 ms to 2 s), Rate the modulation speed (0.1 to 10 Hz), Depth how far the delay is swept and Skew the sweep shape; Mix blends the dry and delayed signals and Output trims the level in dB. A Modulation selector sets the LFO waveform — Sine, Triangular, Log (symmetric), Square, Log (asymmetric), Random (uniform) and Random (telegraph). It works in mono and stereo.
The input is written into a circular buffer and read back at a tap that the modulation wavetable sweeps at the chosen Rate, with linear interpolation between samples; the delayed signal is then mixed with the dry input and scaled by the output gain. It processes one sample-frame per tick, in step with WaveWarp's sample-per-sample engine.
