ltering, but needs more CPU.
Note: The lters in this device are optimized to sound more like a good, powerful analog
lter cascade than a clean digital lter. The 48 dB Mode especially does not provide a
perfect linear transfer quality, resulting in a slight coloration of the input signal even if all
controls are set to 0.00 dB. This is typical behavior for this kind of lter, and is part of EQ
Three's unique sound. If you need a more linear behavior choose 24 dB Mode or use the
EQ Eight.
21.12 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 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 denes 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.
