Metering Line Input Post Levels
Line input channels, such as program audio or audio from video codecs that are connected via analog inputs
and outputs, are metered at the Recording/Ungated output, as shown in the following figure. Stereo virtual
channels display two meters - one for each physical channel.

Processing with Telephony level_pre and level_post
For telephony channels, the level_pre and level_post for the phone input channel and level_post for
the phone output channels are shown in the following figure. As with the analog input and output channels,
the level_pre is before any processing and the level_post is after the processing.
