About

An LFO walks the signal across the stereo field. Rate, depth, and the oldest trick for making one sound occupy two speakers.

How it works.

A sine LFO at Rate drives a stereo panner's position between full left and full right, with Depth scaling how far from centre it goes. That is the entire effect, it is amplitude modulation applied in opposite directions to two channels, which is also why a tremolo with its channels 180 degrees out of phase turns into one.

The browser preview runs it on a StereoPannerNode with the LFO summed into its pan parameter, all at audio rate. A panner constructs the two channels rather than requiring them, so this works on a mono source, which is the difference between this module and Stereo Widener, whose matrix has nothing to scale unless the input already carries a side signal.

Depth at 1 reaches hard left and hard right, and at the panner's equal-power law that means each channel is briefly silent while the other is full. Pulling Depth back keeps both speakers contributing throughout, which is usually what a mix wants; the extremes are more useful as an effect than as a placement.
