Cleaning 73
Noise sample: If the automatic noise sample settings were not suitable for finding
noisy material, then a noise sample can be selected from the list. There are several
typical noises to choose from.
An even more specific option is to create a noise sample yourself.
Length: The length can be set in ms if the "auto" button is switched off, otherwise the
length of the noise sample will be determined automatically.
Pick: generates a noise sample. A short noise sample is taken from the selected play
range. The playback marker can also be moved with the transport console when the
dialog is open to search for a suitable position. If the playback position is between two
objects, a noise sample cannot be generated. The play button allows the noise sample
to be previewed for testing purposes.
Wizard: This opens a wizard that helps to create the noise sample. The wizard mainly
consists of a search function which helps you find the suitable noise sample in the
audio material. Various types of noise can be selected.
Save: The noise sample created can be saved in the noise sample folder. It is then
available as a new noise sample in the noise sample preset list for any other project.
Audio type: Set the type of edited audio material here, and the algorithm will be
adjusted accordingly.
Removed noise: The part of music that was filtered out by the DeNoiser can be
previewed for testing purposes.
Processing
Anti-noise: In this mode the DeNoiser works in an optimized mode to remove noise.
Anti-hum: In this mode the DeNoiser works in an optimized mode to remove tonal
interference. This includes feedback from power cables, power humming, PC fans,
video cameras, or ventilation noises.
If the "Max. damp tonal noise" option is active, all sounds of this kind will be removed.
The "Reduction" controller now affects all possible existing noise components
simultaneously. This makes sense because 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 in the wanted signal.
Noise level: The threshold of the noise reduction function should be set as precisely
as possible. Values that are too low will result in insufficient noise dampening which
causes artefacts like interference 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.
