Dehisser
The Dehisser was especially designed to eliminate the band noise, which is all so typical for analogue
tape recordings, micro-preamps or AD-transducers.
Noise Level: Here you will have to determine as exactly as possible the noise level at which the
Dehisser starts to work. If you choose a level that is not high enough, the band noise will not be
completely eliminated. In such a case you will notice tweeting sounds (the so called "melodic band
noise"). An excessive value will result in a dull sound as part of the band noise and part of the original
audio signal recording will be eliminated by the Dehisser as well (for example: air intake sounds of brass
instruments) (see Artifacts
)
If the noise level on your recording is low, you should experience no problems while adjusting it.
Adaptive: The value for the noise level parameter is set automatically by determining the hiss contained
in the signal. If the noise level value is changed, its effect is then relative, i.e. the resulting value is
determined from the automation as well as the noise level fader
settings.
One advantage is that you no longer have to set the noise level value manually and that this value can also
be adjusted later if the noise share fluctuates, for example, if you use music tracks with differing hiss levels
within one project.
If the noise level is constant, a better result may be obtained manually (Adaptive off). However, the noise
level value must then be set precisely.
Audio type:
Lets you set the audio material that is to be edited; the algorithm is adjusted accordingly.
Noise Reduction:
this option allows you to adjust the damping of the band noise in decibel units. In many occasions it is the
best solution, not to eliminate the noise completely, but to damp it only -3 - -6 dB, hence maintaining the
natural sound of the original material.
Quality: The processing quality can be set in two stages. You can use this to precisely adjust the values
in the dialog
for standard quality adjustment without skipping playback, and can then select a higher quality for final
burning.
Removed:
This option allows you to listen to the music that would be filtered away by the Dehisser.
