DeNoiser
The DeNoiser removes persistent background noise like computer humming, hissing, noises from sound
cards, disturbance from ground wires, interference from audio
-equipment with high-impedance outputs (e.g. turntables), or other device noises. Subsonic noise or
rumbling can be removed effectively from LPs with the rumble filter.
The DeNoiser requires a short section from your music which contains a sample of the audio distortion,
usually from the start or end of the recording.
When the DeNoiser is activated in the project for the first time, a sample of the distortion will be
searched for immediately after the playback marker. The automatically detected noise sample enables
good results to be achieved even without opening the DeNoiser dialog
.
For more specific results, open the dialog with the "Edit" button
.
Noise sample
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 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.
