5.5.8.1 Spectrum Processing Modes

When applying processing to a spectrum region in the Spectrum Editor you can use a variety

of different modes:

Damp

This is used to attenuate the level of a region. The Gain parameter speciﬁes the level of the

attenuation (it is also possible to set positive gain values, i.e. to boost the frequencies in the

region). Three ﬁlter types are available to perform the damping:

Bandpass ﬁlter: All frequencies in the region are equally attenuated.

Low-pass ﬁlter: Higher frequencies in the region will be more attenuated.

High-pass ﬁlter: Lower frequencies in the region will be more attenuated.

For the Low- and High-pass ﬁlters, a low Filter steepness setting is normally used (around 6

to 18dB).

Blur peaks

This ﬁlter operation analyzes the region to ﬁnd the frequencies with the highest level. The

level of these frequencies will be attenuated (or boosted) according to the set Gain value. If

the gain is negative, these frequencies will be "blurred" and disappear in the mix as a whole.

The purpose of the ﬁlter is to mask the loudest frequencies (e.g. it could be used to eliminate

a sudden burst of pitched but unwanted sound in the audio material, like acoustic feedback).

This mode works best with the Inﬁnite steepness setting, which is automatically selected

when Blur peaks is used. You can, however, freely set any Filter steepness setting. The ﬁlter

type options are not available when this mode is selected.

Dispersion

This is a special ﬁlter that "smears" the dynamics and pitch of the region, without changing

the actual frequency content. This works best on lower frequencies, to mask the identity of

a signal without changing the frequency spectrum.

This mode works best with the Inﬁnite steepness setting, which is automatically selected

when Dispersion is used. You can, however, freely set any Filter steepness setting. The ﬁlter

type options are not available when this mode is selected. Dispersion can also be used to

create special effects as it warps the sound in an unique way.

Fade Out

This can be used with any of the three ﬁlter types (Bandpass/Low-pass/High-pass). It grad-

ually ﬁlters the frequencies in the region along the time axis (from nothing at the left edge of
