3.4.4.2 Upmix Panner Parameters (for stereo Channels only)
Still a significant number of stereo sources is used for a typical surround
production, so these need to be brought into the 5.1-channel format. The
upmix panner is a way to pan stereo signals to a surround mix, providing the
possibility to ‘unwrap’ a simple stereo signal to a surround sound field.
Every stereo channel can be equipped with the upmix panner. There are three
operating modes: ‘Normal LR’, ‘5.1’, and ‘5.1 width’ modes. ‘LR’ mode is
normal stereo panning; ‘5.1’ mode uses ‘standard’ amplitude panning, where
e.g. the left channel is sent to the left surround speaker, etc. The most uncom-
mon of these modes is ‘5.1 width’.

Selector for the upmix panning mode.
The remaining parameters are the same as described in the chapters before,
with one exception:
WIdTh in 5.1 WIDTH mode. This is a special algorithm (using Harman corporate
intellectual property), extending the stereo width control to the rear channels
as well.
