are several typical distortions available, e.g. camera noises or power mains
humming.
An even more specific option is to create a noise sample yourself.
Create noise sample
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 be moved with the transport
control when the dialog is open to search for a suitable position. If the
playback position is between two objects, it's not possible to generate a noise
sample. Play 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 distortion types 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 customized accordingly.
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
