Auto Normalize: Selects Normalized (LED illuminated GREEN) or Fixed (LED not
illuminated) adaptation rate. Normalized is recommended. When Auto
Normalize is enabled, the specified Adapt Rate is continuously power
scaled based upon the input signal level. This generally results in faster
convergence for a given Mu. When Auto Normalize is not enabled, the
specified Adapt Rate is utilized at all times without power scaling
Prediction Span: Sets the number of samples in the prediction span delay line. Prediction
span is indicated both in samples and in milliseconds, and can be
adjusted from 1 to 4096 samples. Shorter prediction spans allow
maximum noise removal, while longer prediction spans preserve voice
naturalness and quality. A prediction span of 2 or 3 samples is
normally recommended.
Filter Button: Used to switch the 1-Channel Adaptive filter in and out of the process
without affecting the other filters in the process. The Filter LED
indicates that the filter is “in” when it is lit RED. The filter is out of the
process when the Filter LED is unlit.
Adapt/Freeze Button: Used to freeze this adaptive filter independently. The filter is adapting
when the Adapt LED is lit. The filter is frozen when the Adapt LED is
unlit.
Clear Button: Used to reset the coefficients of the 1-Channel Adaptive Fitler to zero
without affecting any other adaptive filters in the process.
Store Button: Used to store adaptive filter settings and coefficients. This button is
disabled in Stereo-Linked mode. See section 4.4.1.1: for more
information.
Recall Button: Used to load previously stored adaptive fitler settings and coefficients.
This button is disabled in Stereo-Linked mode. See section 4.4.1.2: for
more information.
NOTE: The Filter, Clear, and Adapt/Freeze buttons are also available in the Filter block for each filter
on the Master Control Panel.
