Upmixing - where are we at? Have people compared upmixers?

[Magnus]

Wow.



ALL of the upmixer "screw" with the stereo layout. Auromatic is nothing more than a multimono copy machine with delay added. The very action of moving signals upward(even if you leave the main information alone) will still spoil the stereo image because of the additional channels. Your point is pointless here.




Anytime anyone says "night and day difference," my hyperbole alert goes off. If auromatic ADDS anything, it is changing the stereo mix. DSU does not ADD anything, and neither does Neural X. Auromatic does NOT add anything, and all alter the stereo mix. The very nature of upmixing alters the stereo mix.





Before you make this statement, you should test it. Otherwise, it is false information. You don't know how Neural X will handle Dolby surround or PLIIx until you actually test it. Not buying what you are selling here.



Well, considering PL hasn't been used in AVR in decades, I am not sure anyone can test out your theory except those still living in yesteryear.


PL does not upmix to heights, so comparing it to upmixers that do is kind of airheaded.

I'm sorry, but you're talking out your backside at this point. It's clear you know nothing about the subject, but have to act tough anyway. I'm putting you on permanent ignore a d I suggest anyone with a brain on here do the same.

All upmixers alter the stereo signal. Some listeners prioritize preserving the original presentation and others prefer a more enveloping, redistributed sound.

I think some of this might be due to what people mean by altering the stereo signal.

If we mean changing the perceived imaging then yes, all upmixers alter that. How they do that and to what degree varies on the upmixer and how it is adjusted. if it is adjustable.

However, if one means it as the output L/R channels are the same as the input L/R channels then the answer is that some are the same and some aren't. Most do change L/R (steer or remove materials from L/R) but not all do.

Most upmixers do 'add' things as well, even if it is simple stuff like delay or low pass filtering on surround channels. Others do more such as phase changes, adding generated reverb (sometimes just for height channels) and so on.

One of the fascinating things, to me anyway, about the original information for Quantum Logic processing was the claim that you could take all the output channels from the upmixer and sum them back to 2 channel and the end result would be bit perfect to the original 2 channel source.

soundmixer , don't read him , or you can't listen to him since he hasn't made a video to post here with him in the video , he just hides behind his computer , so what anyone in the film industry , hollywood is full of

the upmixer is a just a matrix trash version of ether pro-logicIIx stripped down for dolby labs trash atmos , ( it takes sound from front left right and passes though one of the few outputs of PLIIx the side surround output or rear surround to frequency mask typical cross-talk , but listen carefully you can hear that it's a cheap scam )

dts neural x ( it takes signal though its matrix decoder that is a stripped down of one of their other matrix decoders , it takes signal from the side surround and plasters it onto the overheads , another cheap scam in all these trash AVR's even trash trinnov , trash storrmaudio , its the same thing , a scam

to do a diy version is simply and can be applied to any other sigh i hate calling it this , 5.1 as that is all you lot here understand ? sigh old AVR can easily be rigged same goes for 7.1 AVR , ( don't need this garbage trash from hollywood , filmmixer soundmixer that luck around ) stuff their art craft in mixing trash atmos movies , its not 3d audio sound , its a scam , its more or less 2 1/2 d sound , shame on you dolby labs for scamming the pubic , wow soundmixers must be idiots to think they are mixing 3d sound for on those cheap lousy dubbing stages for the cheap rubbish cinemas for the cheap homes , sigh what a total 15 years of a scam

 

[Andysu]

I've never heard anything negative from MOVIE sources using stereo inputs to it (other than music going overhead, which many Atmos movies purposely do). In fact, it sounds almost identical ar ear level to DSU. Overhead is often more precise with Neural X.

I think the Neural X doesn't work with stereo is an old wives tale.

dts neural x standard the way it and dolby labs trash ( up i mean matrix decoder ) are garbage trash , auro that's a totally dead sound format
everyone has been yet again , 15 years ago , tricked and conned and scammed with a new trashy rubbish garbage trash by big names and junk dubbing stages sent out to worthless garbage cinemas to the utter worthless homes
i'd rather urinate on my trinnov alt 32 than play anymore trash dolby atmos dubbing trash mixes again

 

[Chr1]

Damn... I take it you are not a fan of those upmixers?

Are there any that you like?
(I think we've established that taste in them can be subjective.)

If not, I'm not quite sure why you are here.
The threads title isn't "Free for all...Come and trash all upmixers."
Just sayin'

 

[john61ct]

It is entirely possible you know what you are talking about. It might even be the case that (some of?) what you write is true.

However the WAY you present your ideas is so off-putting it's really hard to grant them any credibility

All hat and no cattle

Hi people. If you hang out here frequent enough, you'll find out that this is just Andy being Andy. Andy is, may I say, a bit eccentric

 

[Andysu]

upmixer ain't an upmixer its a cheap rubbish matrix decoder cheap dolby labs marketing scam of 15 years of lies

 

[Magnus]

Ain't no crocodiles out there but a fast moving Chevy to sure make a mess of ya.

Ain't no crocodiles out there but a fast moving Chevy to sure make a mess of ya.

look at those snappers they are far better than an dolby labs upmixer , well after they've finished chewing on ya ' yummy , yummy upmixer

yeah will call it the gatormixer , the gateinator i'll be chewing back , oh no not mr gator

trinnov alt 32 upmixer is rubbish
okay lets get this back on track , upmixer is it worth it or should it go in the cat litter ? hey i'm just as disappointed with doby labs scamming atmos

I guess this means he took his ball and jacks and went home........

I would say uneducated.

So, in the early days of surround, I had a Lexicon DC1 and then an MC1...

These used Logic7 which did a fantastic job of upmixing stereo Dolby Surround to 5.1 or 7.1 channels...

Then there was Dolby's own PLII - variable, but frequently OK ... varied dramatically with different implementations by different vendors

Now Dolby has deleted PLII, and released a new "Dolby Surround", meanwhile we have Harman with Logic16 replacing the old Lexicon Logic7, DTS with Neural surround upmixing, and there is a buzz around Auro 3D as an upmixer

So where are we at? What sounds good/best today?

What works best for Music (stereo)?

What works best for Movies (stereo to 5.1, or 7.2.4.... 5.1 to 7.2.4)?

Thanku for such informationional post.
