22.12 Erosion
The Erosion Effect.
The Erosion effect degrades the input signal by modulating a short delay with filtered noise or
a sine wave. This adds noisy artifacts or aliasing/downsampling-like distortions that sound very
”digital.”
To change the sine wave frequency or noise band center frequency, click and drag along the
X-axis in the X-Y field. The Y-axis controls the modulation amount. If you hold down the [ALT](PC)
/ [ALT](Mac) modifier key while clicking in the X-Y field, the Y-axis controls the bandwidth. Note
that bandwidth is not adjustable when Sine is selected.
The Frequency control determines the color, or quality, of the distortion. If the Mode control is set
to Noise, this works in conjunction with the Width control, which defines the noise bandwidth.
Lower values lead to more selective distortion frequencies, while higher values affect the entire
input signal. Width has no effect in Sine Mode.
Noise and Sine use a single modulation generator. However, Wide Noise has independent
noise generators for the left and right channels, which creates a subtle stereo enhancement.
