How to downmix 7.1 and 6.1 to 5.1 2007-11-16 22:59:20 Hey guys,I'm trying to figure out how to properly downmix 7.1 and 6.1 audio tracks to 5.1. I've checked what the Nero Audio decoder does when it downmixes a DTS-ES 6.1 track and it seems to do either "SL = 1.0 * SL + 0.7 * BC" or maybe it's "SL = 1.0 * SL + 0.707 * BC". Not totally sure.For 7.1 downmixing would I also simply mix "SL = 1.0 * SL + 0.7 * BL"? Or do I need to do something different in that case?Finally, do I need to check for clipping and adjust volume if there is clipping? Well, I think surround channels usually don't have such high volumes, so clipping is not that probable, but safe is safe, right?Thanks for your help!!
