A basic flanger building block without feedback. A very short modulated delay line (base Delay 1–10 ms) is swept by a low-frequency modulator set by Rate (sweep speed) and Depth (sweep amount), with Skew shaping the up/down symmetry of the sweep. A Modulation selector chooses the sweep shape — Sine, Triangular, Log (symmetric), Square, Log (asymmetric), Random (uniform) or Random (telegraph). It exposes only the core delay-and-sweep stage — there is no feedback, dry/wet or output control — so it is meant as a component for building larger flanger patches.
Each sample-frame the modulator advances one step, sets the fractional read position in the short delay buffer, and the interpolated delayed sample is produced. Advancing exactly one sample-frame per tick keeps it inside WaveWarp's sample-per-sample engine.
