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 con-
trol, 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 typ-
ically 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.
