Detailed Description

Pitch modulation via LFO-driven variable delay.

Modulates pitch by varying a short delay line with a primary LFO. Features FM modulation on the primary LFO for complex, non-static pitch variations, and parameter smoothing to prevent zipper noise during automation.

Threading: prepare() belongs to the setup thread; processBlock() and reset() belong to the audio thread. Setters are lock-free atomic publications, safe from any thread, consumed at the next processBlock(). Non-finite setter arguments are ignored.

Dependencies: Phasor.h, RingBuffer.h, DspMath.h, AudioSpec.h, AudioBuffer.h, StateBlob.h.

vibrato.setDepth(0.5f);         // 0.5 semitones
vibrato.processBlock(buffer);
