Figure 6-4: Automatic Gain Control Dialog
The only adjustable setting available for the Automatic Gain Control is the
maximum possible gain to be applied. In the example above, the maximum gain
is set to 10 dB. If the output signal falls more than 10 dB below the reference
level, then a 10 dB gain will be applied but the output level will still be below the
reference level.
The AGC is useful in near party/far party conversations where one party’s voice
is much softer than the other. The AGC can be used to boost the softer speaker
without boosting the louder speaker. The AGC can also be used to compensate
for losses in signal level which may have occurred as a result of the preceding
filters. For most near party/far party applications, max gain of 10-15 dB is the
recommended setting, as a larger maximum gain may elevate background
noises too much during pauses in speech. A “soft AGC” of 5 dB is often useful
even when large voice level differences are not present.
