The Release Time control adjusts the time it takes the compressor
element’s gain to increase 6 dB after the signal coming from the highpass
filter drops below the threshold. The range of the control is from 0
milliseconds to 3000 milliseconds.
High Pass Frequency Page
De-esser Highpass
Frequency: 5402 Hz
The de-esser can be viewed as a compressor which is keyed by the output
of a high pass filter. When the filter passes a signal whose level is higher
than the compressor’s threshold, the compressor clamps down on the
signal. Since sibilants are primarily broad band noise above 5 KHz, the
filter is designed to pass these signals and attenuate low frequency signals
as much as possible.
The filter used in AVP’s de-esser is a two pole, 12dB/octave high pass
design which effectively distinguishes between sibilants and other vocal
sounds. The range of the control is from 2971 Hz to 20 kHz.
De-esser Gain Reduction Meter Page
DeS:-20 -12 -6 -3 0
Pressing the De-Ess button while the De-esser page is displayed will display
this high resolution gain reduction meter. The meter displays the amount
of de-essing of the signal. If the frequency and threshold controls are set
properly, the meter will display little gain reduction during vowel sounds
and soft consonants, and substantial gain reduction during sibilants.
Pressing the De-Ess button again will return to the De-esser page.
Gain Reduction Meter
The front panel de-esser gain reduction meter is intended to provide a
quick indication of de-esser activity. For precise gain reduction indication,
refer to the De-esser Gain Reduction Meter Page described above. The
range of the meter is 15dB.
