DeNoiser - The best setting
To find optimal settings for noise removal from your material, proceed as follows:
1. Search for a good "Correction" setting. The distortion sound should no longer be
audible. If artifacts should arise, they shouldn't be suppressed by setting a very high
correction value. The result may sound somewhat lackluster.
2. To increase artifact suppression, increase the values for smoothing and/or static
smoothing. Which parameter is most suited depends on the nature of the audio
material from which the distortion is to be removed.
3. Try to slightly reduce the correction. This will result in increased artifacts and an
increase in the "smoothing values" and/or "static filter smoothing". The result is often
an improvement.
4. If you use a high overlap, the results can improve clearly.
5. Drag the "Preserve transients" parameter as far out as possible until noise increases
and the distortion becomes audible at the transients (with hissing, this effect is
recognizable by the type of hissing modulation).
6. In difficult cases, we recommend using the freehand draw filter curve of the noise
sample. Problematic areas can be influenced by increasing or decreasing the
distortion spectrum.
7. If there is no discernible improvement, you can always just try correcting the noise
instead of completely removing it. This can be attempted by reducing the value for
mix dampening.
8. Whether or not artifacts are audible also depends on the monitor volume and the
frequency response on playback. If you know how your work will be reproduced
(cinema theater, on TV, radio...), you should work under corresponding monitoring
conditions.
DeNoiser - Problems & solutions
Problem: The result is silence
Solution: It is probable that your noise sample inadvertently contains the original signal
Problem: Strong distortion, loud tweeting, strong damping of the used signal
Solution: It is very probable that the noise sample contains sections from the original signal.
