Filter Amount Block

Specifies Filter Amount and Output Gain.

Equalize Voice or Attack Noise Filter Amount specifies the maximum

amount of volume reduction that can be applied by the inverse filter

within the specified frequency limits; this may be set to the approximate

difference in amplitude between the largest and smallest input spectral

components within the frequency limits. This value varies between 0

and 100%. 0 indicates no filtering, 100 indicates full filtering. Varying

the Filter Amount will update the blue trace in the Filter Display to

show how the filter is affected.

NOTE: Maximum Fitler Amount should only be used when

necessary; it may excessively elevate background noises

For Equalize Voice operation, the inverse filter response rolls off to -

40dB outside the frequency limits. For Attack Noise operation, the

inverse filter response rolls up to 0dB (no attenuation) outside the

frequency limits.
