opus - Mar 2022 - Antw: [EXT] Opus merging streams

Hello !



I have a question. I'm trying to use Opus on an embedded device which
communicate with several other devices with the same software.

I wanted to know if it's possible to merge Opus packets from different
sources and then decode this merged packet through a normal opus_decode.



I receive in real time 3 different streams of 40ms opus packets. As it
would be consuming too much CPU if I decode each packets and then sum them
together, I would like to decode them together.



Best regards,

Andrew Sonzogni

"merge" means "concatenate"? Or "mix"?

"sum" sounds like "mix", right?
