[opus] Understanding libopus parameters

[Sergey G]

Hi,

I'm looking for the description of possible combinations of libopus parameters. For instance in case of low bitrate encoding (voip application, SILK part) it does not have sense to set 2 channels. Audio applications (CELT part) widely use 2 channels.

What about HYBRID mode? Is it closer to voip or audio applications? What is the typical number of channels? Can constant bitrate be used in this mode?

Thanks & regards,
Sergey
