An advantage of this you no longer have to adjust the noise level manually and the
values are adjusted for fluctuating noise levels, e. g. if you use different tracks with
varying noise levels in one project.
If the noise volume is constant, you may be able to achieve better results by setting
things up manually (adaptive off). But the value for noise level has to be set exactly.
Removed: For test purposes the filtered out audio material from the DeHisser can be
previewed.
Noise Reduction: Here you can adjust the dampening of the hissing in decibels. It is
often better to reduce hissing in smaller increments, e. g. -3- to -6 dB, rather than as
much as is possible to keep the sound natural.
Audio Type: Set the type of edited audio material here and the algorithm will be
adjusted accordingly.
Presets: Here you can select from various DeHisser presets.
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). 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 noise, 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 noise
will be searched for immediately under the playback marker. These automatically
detected noise samples can help with achieving good results even without opening
the DeNoiser dialog.
For even better results, open the dialog with the "Edit" button.
