[opus] Master Audio 5.1 to Opus 2.0 conversion & Center Channel
When it comes to Movie surround audio, the center channel carries the bulk of the speech. I'm converting 5.1/7.1 Master Audio tracks to 2.0 Opus. Is there a way to boost the center channel when converting 5.1/7.1 Master Audio to 2.0 Opus? I don't hear that well when it's playing a lot of music, and I tried the "-application VOIP" when encoding MA to 128-192kpbs 2.0. It makes no difference, and I figured boosting the center channel would be true hands on. I don't see anywhere in your encoding rules that allow channel manipulation. -------------- next part -------------- An HTML attachment was scrubbed...
