Modulation and analysis
Make parameters follow time, the signal envelope or your external controls.
LFO → Gain → MixMove the controls: Rate changes the speed, Depth changes the modulation range. This is a visual model without audio playback.
Match the ranges
The default LFO outputs −1…1. For Gain 0…1, use Amount 0.5 and Offset 0.5. Use Map Range for filter frequency and Clamp to explicitly bound the result.
Parameters with a Number input can be modulated. Switches, shapes and memory sizes without such an input are static.
One signal feeds two branches: dry and processed.
Select a node to trace its connections. This diagram explains processing; it does not play audio.
Control sound with sound
Envelope Follower turns Audio level into a Number with Attack/Release. Peak Detector measures instantaneous peaks; Window RMS measures windowed energy. Audio to Number extracts a sample and is not a level detector.
Smooth, Attack / Release and Slew Limiter control how quickly values change. Sample & Hold captures a value on a rising Gate edge.
