classTremoloEffect

Tremolo effect that amplitude-modulates the signal with a sine LFO using native WebAudio nodes. A sine-wave LFO drives a `GainNode`'s gain to produce the characteristic volume pulsing of tremolo. The base gain is `1 - depth` and the LFO peak deviation is `depth`, so the gain oscillates between `1 - 2 * depth` and `1`. Optionally the same LFO can drive a `StereoPannerNode.pan` for a synchronized auto-pan effect. Node graph (`autoPan = false`): ``` inputGain ┬── dryGain ──────────────────────────┐ │ ├── outputGain └── tremoloGain ── wetGain ─────────────┘ lfoOscillator ── lfoGain (depth) ── tremoloGain.gain ``` Node graph (`autoPan = true`): ``` inputGain ┬── dryGain ──────────────────────────────────┐ │ ├── outputGain └── tremoloGain ── panner ── wetGain ──────────┘ lfoOscillator ── lfoGain (depth) ── tremoloGain.gain lfoOscillator ── panGain (depth) ── panner.pan ``` Gains: `dryGain.gain = 1 - wet`; `wetGain.gain = wet`; `tremoloGain.gain` base = `1 - depth`.
