Ableton/Live/UG/29 Audio Effect Reference/17 Erosion
- Erosion degrades the signal digitally by modulating a short delay with a sine wave and filtered noise, from noisy artifacts to downsampling-like distortion.
- The display shows the input spectrum and the modulation, and works as an X-Y pad: horizontal sets Freq (sine frequency and noise filter center), vertical sets Amount.
Option (Mac) or Alt (Windows) makes vertical dragging set the noise filter width. - Noise Blend — 0% sine only, 100% noise only. The sine is drawn as a solid vertical line and the noise as horizontal dotted lines; icons below brighten to show which dominates.
- Filter Width — bandwidth of the noise filter; disabled at Noise Blend 0%
- Stereo Width — mono (0%) to stereo (100%) modulation
- Sets made before Live 12.4 load the older device, now called Erosion Legacy.
