Spectral view
"Spectral view" shows the spectrum of the noise sample by default. It can be
switched to spectrogram view by pressing the corresponding button on the
right-hand side. In this case, the played audio material is shown as a
spectrogram. The spectral sections removed with by the DeNoiser are
displayed in red.
Mode
Anti-noise: In this mode, the DeNoiser works in an optimized mode to remove
particularly "noisy" distortions.
Anti-hum: In this mode, the DeNoiser works in an optimized mode to remove
tonal disturbances. This includes feedback from power cables, power
humming, PC fans, video cameras, or ventilation noises.
If the option "Max. damp tonal noise" is active, then this type of distortion will
be completely removed. The "Reduction" controller affects all possible existing
disturbances. This is a sensible step, since tonal disturbances are much more
annoying than other noise – a small amount of "extra" noise in the recording
may be allowed in order to avoid a greater loss of highs throughout the desired
signal.
This option can be found in "Hum" mode under the "Noise level" controller in
place of the "Adaptive" parameter (not available in "Hum" mode).
Processing section
Quality: The quality of the calculation can be set in two stages. You can set
the values in the standard quality setting precisely without influencing the
playback in any way and select high quality for burning once the material is
ready.
Noise level: The threshold of the noise reduction function should be set as
precisely as possible. Values that are too low will exhibit too low a distortion
dampening level and result in artifacts like noise or "twittering" (see below).
High settings produce dull results – useful signals that sound similar to hissing
noises are also filtered away. Take your time to find the best setting for the
individual case. If the "Adaptive" option is activated, the setting is relative, i.e.
in addition to automation.
Reduction: This sets the balance between the original signal and the signal
with the applied noise reduction.
