19.9 Erosion
The Erosion Effect.
The Erosion effect degrades the input signal by modulating a short delay with ltered 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 eld. The Y-axis controls the modulation amount. If you hold down the
Alt
(PC) /
Alt
(Mac) modier key while clicking in the X-Y eld, the Y-axis controls
the noise bandwidth.
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 denes the noise
bandwidth. Lower values lead to more selective distortion frequencies, while higher values
affect the entire input signal. W idth 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.
