Surround Sound Upmixer History & Comparisons w Roger Dressler of Dolby Labs

Ойын-сауық

Audioholics is honored to have Roger Dressler, formerly of Dolby Laboratories, as our livestream guest for 4/26/22 @ 10:30pm EDT. Roger Dressler joined Dolby Laboratories in 1982, just in time for the introduction of its first consumer Dolby Surround system. During his 25-year tenure, Roger helped Dolby develop and license Dolby Headphone (Lake DSP), Pro Logic II (Fosgate), and MLP Lossless and TrueHD (Meridian Audio), and to get its coding technologies adopted in DVD and Blu-ray Disc formats.
Roger will discuss the history of surround upmixers, their limitations, and the changes going from Dolby Prologic II to the Dolby Surround Upmixer. Roger will discuss some of what led up to the adoption of Fosgate's technology as PLII over Citation 6-Axis and Lexicon Logic7, to build upon Paul Scarpelli's article.

    Pro-Logic IIx was wonderful for converting Stereo music to 5.1. Intrigued Roger rates Auro-Matic so highly. WIll definitely consider it now :)

    My SONY STR DN-1020 does an absolutely amazing job of upmixingba 2.0 sound input to surround sound. It doesn't play the same sound on all speakers it separates the audio as if it's actual 5.1. For instance if I'm watching something in stereo with a helicopter passing from front to back I hear the helicopter coming from behind then faded to the front speakers

    Best topic yet! For anyone interested in upmixing 2ch to front wides, older upmixers like Audessy DSX and DTS Neo X will upmix 2ch with front wides. For newer upmixers DTS Neural X is really the only option for upmixing 2ch up to 7.1 with front wides . You can also layer DTS Neural X on top of DTS X for front wides but you cannot layer DTS Neural X on top of Dolby Atmos. Some very high end processors will support front wides with DSU and Atmos but they are rare and expensive.

    Great to see Roger’s slide praising Auro 3D and Auromatic upmixing at the 41:06 mark. One of the limitations not mentioned with Auromatic vs DSU vs DTS:X when up mixing two channel audio is the inclusion of the TM left & right channels with Dolby & DTS. -Auro 3D will leave those two channels out in a 7 surrounds . 2 subs. 6 heights configuration while upmixing. However we still prefer Auromatic over the other two upmixers (most but not all of the time) mainly for two reasons. 1. The bass is more hard hitting. There is no denying this while switching between the decoders on countless source material comparisons. 2. Auromatic sounds the most natural while still staying true to the artist’s intent for our ears. This is subjective of course but Roger said it best at the 38:30 mark..”It’s all about what I like to hear my audio do. There’s no shortage of opinions on that.” Thanks for doing the interview GD.

    I love pro dolby pro logic .music setting in my 5.1 surround. Depending on the original mix im often blown away by the surround effect. It creates space between the instruments with the lead vocals front and centre as they should be. I just close my eyes and the soundstage envelops me... stereo seems bland and constricted by comparison. I find dolby pro logic movie setting good for stereo 2 track movies. I need nothing else. Easily pleased. 😀

    THANK YOU again for the reminders to hit like... some of us are older. LOL God I just love the nerdy stuff you graciouslly allow us to get into on your channel. Having this Icon of Dolby lineage gave us such a backgrounder on Dolby's formats was just beautiful. Maybe there's a DTS guy whose brain we could also pick some day? You could feasibly get Wilfried Van Baelan to suss out his formats strengths and handicaps, he's been on other KZread vid channels. I kinda wonder what effect COVID seclusion has had overall on streaming, CES, home theatring in last 2 years. I suspect it has saved home entertainment from drifting back to atrocious 2 channel phone/tabby lossy theatring . Is there manufacturing data that shows any of that trending? CES marketing data? THX again ole friend for a GREAT interview for the vast permanent Web library. We are all getting older and these valuable histories deserve to be chronicled. :)

    I was never a fan of DTS Neo 6. I absolutely love DTS Neo X. And I think DTS Neural X sounds pretty good. My favorite upmixer was from Neural, I believe that a Company called Neural Surround from Kirkland, WA sold out to THX and it was then renamed Neural THX. Then DTS purchased Neural and Named it DTS Neural but I don't think the technology changed until DTS adapted Neural to the newer Neural X to work better with mapping to object based systems.

    Wow! Roger Freaking Dressler! Damn, Gene! Lucky you! I hope you bought a lottery ticket that day. I could watch this more than a few times. This is an audio lifeblood extravaganza. This is audio manna from Heaven. What more can you say? Trying to explain this stuff to my boss Michael Mann back in 1997 was a no go, even as much as he was interested in music and multitracks for his films. Unfortunate that the person in his life with the most interest and knowledge on Jim Fosgate’s efforts (I owned the Fosgate Model 3 at the time - with Bob’s proprietary 7 channel circuits - powered with multiple Krell Class A KSA 100S’s), was me, his lowly personal assistant. “What do you mean sides and backs? When you’re editing at Todd AO, there are just 5 speakers. There’s no such thing as 7 or 9 speakers in a Cinema!” Don’t get me wrong, Michael was one of the smartest men I’ve ever known or worked for (really nice vocabulary, but overly worked around the edges and his 20 plus year-old BA in English and technical neutering of romance words, were bugs in the otherwise well read nature that all genius draft dodgers involved in the advanced writing arts seemed to have stumbled upon through their daily THC regimen and innate and incessant drive to show their true intellectual stripes [they muse they could go to war with] could get annoying). However, he did have some dated ideas and some of his go to facts (standardized pseudo intellectual de facto dogma, really) facts were decades old. These were passed off as sage crumbs I was to gobble up. I was just a $150 a day kid to him, and that was fine. Ultimately, he thought I was too big for my britches, even though I always stayed quiet through his mistakes and false memories. I was there to help and not biting my tongue or educating him, would have surely gone much worse. But having to shut up about Bob Fosgate, his favorite Westlake Audio studio monitors (the most popular monitors ever known to man - according to him), and many others, drove me nuts. But the Bob denial thing and extra channel upmixes (when I had it fully working at home) I wasn’t permitted to pursue, were the worst. Intellectually stifling at best. Out-of-control-freak asleep at the wheel, was what I really thought. I mean, just look at all the mistakes in his movies. And that terrible ending for Heat that he wrote the entire movie around. Just so inexplicably out of character for Neil, no person that possesses a superior intellect and is a logic based thinker, could ever accept that as realistic in anyway. And Neil hesitates? Basically, Neil was either FOS, or a closet simp that lost his life without even losing the girl because the girl totally and completely corrupted him. All of his basic character traits, were well established, then they got dump trucked like a bad QB (D.H.) walking on the freeway to get gas. Yes it’s supposed to be fantasy. However, suspension of disbelief is supposed to be a goal.

    I don't believe Trinnov has released the new DSU update yet that supports Front Wides, select D+M AVRs received the update back in November 2020 & I think JBL Synthesis/Arcam products have the DSU Front Wides upmixing functionality too but there is an issue in the current Atmos decoder version v1.6.2/1.6.3 concerning DSU's Dialog Bleed problem leaking into the surround speakers that has been reduced but not eliminated in v1.6.3 SDK which hopefully Dolby will issue a proper fix in v1.7.2 or the eventual 1.8.x SDK update.

    So I’ve done it a few years ago when I had a dedicated cinema room. I ran all 7 bed layer speakers full range, they were each full range towers with integrated 12” THX select subwoofers. At the time we were limited to Audyssey XT32 so I ended up grabbing a few MiniDSP’s and adding PEQ up to 500hz manually. They were all Snell towers and sounded phenomenal but the amount of time it took to get things sounding right was quite the task.

Sorry might be off topic but many have been waiting for this . From my email : “To enable 4K120 / 8K60 pass through once firmware update is complete you will need to change the ‘HDMI Video Format’ setting to ‘8K mode’. To do so please open the AV receiver’s on-screen menu. Select ‘Video/HDMI’ then ‘HDMI Video Format’ then the ‘HDMI input’ and select the now available ‘8K Mode’.”

    This all could be interesting if you explained the myriad of terms that you use. There seems to be a total disregard for those who might be listing. Why do you publish? To attract only the well informed. How may of those listeners do you have? You could re-broadcast this same video for dummies and stop the recording, to explain what you just said. You might find yourself attracting new more viewers, but, maybe you don't need any more???? Ok then, excuse me.
