Fader

Delay

Telephone Controls

The fader control enables the user to add gain or attenuate the telephone signal
from +20 dB to -100 dB with a resolution of 0.1 dB. This gain is applied in the
digital domain.
A maximum and minimum gain range can be specified for the faders to limit
the user gain control. The process of setting the min and max volume controls
is described in the input fader section.
There is a fader control on the phone input channel and a fader control on the
phone output channel.
The delay processing allows the designer to add from 0 to 1000 milliseconds of
delay on both the telephone input and output channels. While the delay is set
in milliseconds in the user interface, it can be manually set through the com-
mand API in samples where each sample represents 1/48 of a millisecond.
In addition to the audio processing paths described in this section, telephony
channels have additional user controls to configure the telephone interface.
Select the Phone Settings... button to get access to the telephony specific
controls.
