Channel routing
In single-user model, the channel assignments of the Realiser making the PRIR measurement do not
need to be the same as the channel assignments of the Realiser used for playback. For example, if the
measuring Realiser were assigned:
1 Left
2 Right
3 Left surround
4 Right surround
5 Centre
6 LFE
and the playback Realiser were assigned:
1 Left
2 Right
3 Centre
4 LFE
5 Left surround
6 Right surround
the PRIR would nonetheless play back properly, because the playback routing is done by channel
label, not by channel number.
However, the re-routing of channels cannot be done separately for each user in dual-user mode.
Therefore the channel assignments of the PRIR in preset 4 must match the assignments of the PRIR in
the preset chosen by the first listener, because it is the first listener’s assignments that will determine
the routing for both listeners. Otherwise the second listener will hear channels coming from the wrong
virtual speakers.
