Members rhythminmind Posted January 25, 2007 Members Share Posted January 25, 2007 For you surround guys out there here allittle something you might find interesting. I've been dealing with setting up a new console for 7.1 mixing. It requires new code for the board.There has been allot of debate how the surround panner/pan laws will act in 7.1. Mostly what will happen with the panner in the center position?It is more complicated then one would think.. The mid surrounds have added a new element. It makes it quite different from 5.1, or 6.1. After what we have figured out 6.1 is my preferred format until 8.1 becomes common place. We have come up with what we want it to do, Now waiting for dolby to give there input. I would like to hear how you all would initially expect it to work. I'll let you know if it matches our conclusions. Link to comment Share on other sites More sharing options...
Members doug osborne Posted January 25, 2007 Members Share Posted January 25, 2007 There is no standard 7.1 format, and 6.1 delivery today is only via 6.1 formats like Dolby EX and DTS ES. How do you intend to deliver this (any rumors about 8-channel music via Blu Ray or HD-DVD?). And 6.1 can have the Cs matrixed or discrete, delivered by one speaker for rear imaging or an array for a diffuse soundfield... Pan Law may or may not be an issue - you should be able to mix using 0dB Pan Law and have it translate, as long as you are not mixing it on more than one console or DAW - but Downmix certainly is. Address this properly, and you can mix in 7.1 and have the downmix to 5.1, 2-channel, or Mono work properly. A true Stereo image in a typical living room presentation certainly needs a height channel, surround channels with speakers directly to your sides, and a Cs, in addition to the common 5.1 implementation. Panning a sound to the center - do you mean, for example, a mono signal panned to the listener's head? - will result in multi-channels of headroom, and headphone-like imaging.

Members rhythminmind Posted January 25, 2007 Author Members Share Posted January 25, 2007 "There is no standard 7.1 format" Exactly. theres about to be now.. We do allot of 5.1 ,6.1 home theater mixes. We just got our 1st 7.1 client request. So this is why we are figuring this out and getting the consoles updated to handle it (software code). That means trying to figure out how the surround panner will respond. And yes the down mix is even a bigger issue. We do allot of Dolby & DTS Beta testing. Thats why i was curious what your initial ideas of what the Mid surrounds would be doing when the surround panner is dead center in the middle.It wasn't what i initially thought. Thats why i wanted to start this thread in the 1st place. I thought others would find it interesting as well. Link to comment Share on other sites More sharing options...
Members rhythminmind Posted January 25, 2007 Author Members Share Posted January 25, 2007 This is now getting fun =)... Here is the chain of communication going on.. We asked the console manufacture to give us 7.1.They ask us how we want it to work.We come up with our thoughts.Contact dolby engineers for there opinion on this. They turn out to have the same questions we have. Turns out the manufacture has contacted them as well..Fun stuff.. Link to comment Share on other sites More sharing options...

We don't image well - we can't place a phantom image - from directly to the right or left of us. That's why, as with the Cs, a single speaker on each side is the best approach to brute force the R/Rs and L/Ls phantoms. We don't image these left and right phantoms well, but we do hear them as a diffuse soundfield, and even with discretes mix channels and speakers there, the perceived level from the mid surrounds will be low.

Yes i agree.. This is why i like 6.1 better then 7.1 with 7.1 you don't have that discrete center. It's a glorified 5.1. But those mid surrounds cause a muck in the semi standard of having the center image down the middle from front to back when the panner is dead center in the middle. Like it is in 5.1 and 6.1.. Look at this for something interesting. Thats one way to look at it.. Took me for a surprise. 180 from the norm Link to comment Share on other sites More sharing options...
