click on a peak to set up the plug-in to remove that frequency.
Auto Mode is suitable for tracking a weak, slowly wandering fundamental and operates
over all three frequency bands. Fast tracking mode allows the removal filters to
automatically follow a quickly wandering fundamental. This mode operates on MF and HF
frequency selections only (if Fast is selected in the LF range, the mode is forced to Auto
and the Auto button flashes). Auto and Fast modes are both applicable to Comb or
ParamEQ settings. Fast mode is most appropriate for quickly drifting high frequency
buzzes possibly generated by lighting interference.
3.3 RemovalFilters
The default removal filter is a Comb filter. However, you can also select ParamEQ mode,
which means using sharp parametric EQ sections to remove the fundamental and
harmonics. Generally, if the buzz contains many harmonics, or if the frequency of the
buzz is wandering, it is best to use the Comb filter. If there are only one or two harmonics
to remove, then you may find that you prefer the sound of the parametric EQ filters.
The Comb filter has equal width notches when viewed on a linear frequency scale, which
means that the notches will be narrow at higher frequencies. For removing a wide-band
buzz that has a low frequency fundamental the Comb filter will do least damage at
HF.
For similar settings of fundamental frequency and Q, the ParamEQ filters will be narrower
at LF than the Comb, but will widen as the harmonics and frequency increase and at HF
will be wider than the equivalent Comb filter section. With parametric EQ filters, the
