Waveform Filter

Applies a smoothing filter to the waveform visualization.

video-wave-filter accepts a filter name as a string. The average filter smooths the waveform by averaging amplitude values across neighboring samples, reducing spikes and producing a cleaner visual representation.

This parameter is most effective when combined with video-wave-samples to control the number of samples used in the averaging window.

See the Audio Waveforms overview for the full set of waveform parameters.
