D<strong>en</strong>oiser<br />

The D<strong>en</strong>oiser eliminates or reduces any noise below a threshold volume level. The D<strong>en</strong>oiser<br />

uses fast Fourier transform (FFT) analysis to recognize frequ<strong>en</strong>cy bands of lower volume<br />

and less complex harmonic structure. It th<strong>en</strong> reduces these low-level, less complex bands<br />

to the desired dB level.<br />

If you use the D<strong>en</strong>oiser too aggressively, however, the algorithm produces artifacts, which<br />

are usually less desirable than the existing noise. If using the D<strong>en</strong>oiser produces these<br />

artifacts, you can use the three Smoothing knobs to reduce or eliminate them.<br />

D<strong>en</strong>oiser Main Parameters<br />

The D<strong>en</strong>oiser offers the following main parameters:<br />

Threshold slider and field Noise Type slider and field<br />

Reduce slider and field<br />

Graphical display<br />

• Threshold slider and field: Sets the threshold level. Signals that fall below this level are<br />

reduced by the D<strong>en</strong>oiser.<br />
