Artefacts
With incorrect settings, the DeNoiser and the DeHisser may leave behind a
metallic chirping or twittering sound, the so-called artefact noise. The cause of
this is the incomplete removal of the distortion. The ear is quite sensitive to
this sound because of its synthetic character. This problem, in practice, only
occurs in especially difficult cases.
To achieve the best possible results you should pay attention to the following
hints:
 First, select a preset from the selection menu. In most cases the result is
satisfactory.
 Be careful when "denoising" the effect: Less is more! The distortion sound
should no longer be audible, otherwise artefacts may be brought about.
We recommend removing any DC offset that may exist from the material
before using it ("Effects" menu > Cleaning > "Remove DC offset" (view page
80)).
Remove DC offset
This function can only be opened via the "effects" menu and can thus only be
applied to selected objects. This can be useful if your sound card overlays
your sample with a constant DC offset during recording, which leads to
crackling during playback or editing. (This is basically always the case with
recordings that use the integrated sound card of your PC).
