processing on an input signal. This version of the signal has no acoustic echo
cancellation processing and will consequently include any acoustic echo signal
that may be present at the microphones.
Recording/Ungated - Line Input
The recording - line input version includes equalization, automatic gain
control, and the dynamics processing as well as fader gain control, input delay,
and input mute as shown in the following figure. This processing path is
typically used by line input signals such as program audio, and hence the
name line input path.
Recording/Ungated - Conferencing
The ungated conferencing processed input includes the acoustic echo and
noise cancellation as shown in the following figure. This path is typically used
for recording of conference microphones as it includes all the acoustic echo
cancellation but not the automatic microphone mixer processing.
