Sonnox Restoration Toolkit
The Sonnox Restoration Toolkit consists of the De-Clicker, De-Noiser, 
and De-Buzzer tools. The tools are for restoring old material, removing 
clicks, pops, buzzes, and background noise that can occur in new 
recordings.
Sonnox DeBuzzer
Sonnox DeBuzzer allows you to remove hum and buzz noises from audio 
material.

Frequency Knob and touch pad (Hz)
The DeBuzzer has an active frequency range for the buzz 
fundamental of between 20 and 440
 Hz. In Auto mode, this knob 
sets the frequency from which the buzz detection circuit starts to 
hunt for buzz components. In Freeze mode, this knob sets the 
exact frequency of the buzz fundamental. The knob is graduated 
around the circumference, and clicking on any labeled graduation 
sets the frequency to that graduation.

Attenuation knob and touch pad (dB)
Determine the level of attenuation that the buzz removal circuit 
apply, up to a maximum of 96
 dB. Generally this should be set so 
that the buzz is just inaudible. Excessive use of attenuation can 
degrade the signal unnecessarily.
Auto button
Enables Auto mode for the buzz detection circuit. In this mode the 
buzz detection is continually calculated and a slow drift in the buzz 
fundamental frequency automatically...

•Freeze mode should be used to select a specific frequency that 
might be variable in strength. Fine Adjust (which forces Freeze 
mode) can be used to increase the resolution of selecting the 
fundamental.
• If you are still having difficulty finding the fundamental, use the 
Tone control.
• The Hum mode removes harmonics up to 800 Hz. If you can hear 
harmonics that are higher in frequency, select Buzz mode, which 
removes harmonics up to 4000
 Hz. If...

Trim Input Level
Allows you to adjust the input signal level by up to ±12 dB.
Sensitivity Fader and Touch Pad (%) (DePop, DeClick, DeCrackle)
Controls the sensitivity of the detection circuits. Fully sensitive 
might allow the detection circuit to react to low level signals and 
possibly mis-classify programme as pops or clicks. Stronger pops 
and clicks require a less sensitive setting.
In Button (DePop, DeClick, DeCrackle)
Enables the pop, click or...

• There is necessarily some degree of overlap in the detection 
circuits of clicks and crackle. Decreasing the DeClick sensitivity 
can increase the apparent detection of crackle and increasing the 
DeClick sensitivity can indicate less crackle. Best results are likely 
if the two controls are balanced.
Sonnox DeNoiser
Sonnox DeNoiser removes wide-band noise from audio material.

Sensitivity fader and Trim touch pad (dB)
The sensitivity fader defaults to 0.0 dB, which is the midpoint of its 
travel. It adjusts the sensitivity of the noise detection circuit, and 
the visible effect of this is to move the yellow noise contour line up 
and down. The sensitivity level can be changed by up to ±18
 dB.
To reduce the sensitivity and make the DeNoiser less reactive to 
the noise component, move the fader down. The noise contour 
displaces...

A good example is a low bitrate encoded signal, which might be 
band limited to 12
 kHz. Due to the sharp discontinuity, the noise 
removal circuit can introduce audible artifacts around the band 
limit, and setting the HF Limit frequency slightly lower than the 
band limit removes those artifacts.
Attenuation fader and touch pad (dB)
Determine the level of attenuation that the noise removal circuit 
applies in the range 0 to -18
 dB. Generally this should...

Legacy Plug-ins
Under Windows, a set of plug-ins is provided for compatibility with 
audio projects that referenced these effects when using earlier versions 
of WaveLab Elements. An audio montage which referenced these 
plug-ins would otherwise require cumbersome user intervention to 
open, for example.
Their use with new audio projects is not recommended and they are not 
documented.

Dithering plug-ins add small quantities of noise to a signal to...

Bit Resolution
Allows you to specify the intended bit resolution for the final audio, 
after dithering, regardless of whether you want to render the 
settings or play back in real-time.
Dithering changes the sample resolution, but not the sample size. 
For example, when dithering 24
 bit to 16 bit, the file will still be 
24
 bit in size, although only 16 bits of information will have 
significance. When rendering to a 16-bit file, specify the file 
resolution to...
