Detailed Description

Exponential (multiplicative) smoother for natural, perceptual responses.

Use for: Filter cutoffs, frequencies, volumes in dB.

Warning

Geometric smoothing is only defined for same-sign transitions. If the new target's sign differs from the current value (ratio <= 0), or the current value is zero, the smoother snaps instantly to the target: an audible step. Keep this class for strictly-positive parameters (Hz, linear gain); use LinearSmoother or OnePoleSmoother for bipolar values (pan, offsets).
