Freeze button
Enables Freeze mode for the buzz detection circuit. In this mode the buzz
fundamental is fixed to the frequency shown in the touch pad window. This
mode is useful for material with fluctuating buzz level, but with a constant buzz
frequency. In this instance, Auto mode would suffer when the buzz level drops
and would typically re-hunt for a different buzz fundamental. In this mode the
removal filters follow the nominal frequency.

Detect display
Indicates the degree of detection that the buzz detection circuit has achieved.
Output Level meter (dB)
This meter is designed to give exactly 1 dB per LED for the top 18 dB of
dynamic range, and 2 dB per LED thereafter. There is a peak-hold feature that
holds the highest peak, helping to give a better impression of the working
dynamic range.

Trim Output Level
Allows you to reduce the output level by up to 12 dB. Dithering is applied after
output gain control, so it may be necessary to reduce this value by a small
amount to avoid clipping.

Using the Sonnox DeBuzzer
•
Find the nominal frequency. Start with Sensitivity and Attenuation controls
at the default positions (90 % and -48 dB).

•
If you know the rough frequency of the nominal, select that frequency using
either the knob or by typing into the touch pad.

•
In Auto mode, allow the detector time to drift towards the actual fundamental.
The Detect display indicates confidence of hum detection. Auto mode should
be used if the fundamental drifts over time.

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.

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 there are no harmonics above 800 Hz, be sure to use Hum
mode to preserve as much original audio as possible.

•
In order to cause as little damage to the audio as possible, back off the
attenuation until you can just hear the buzz, then increase it until the buzz is
inaudible.
