![]() ![]() I saw Bram Stoker's Dracula in Dolby Digital in San Diego in '92. So yes, after the summer of 1992 a lot of premium theaters were doing the upgrade and by fall it was "dozens", new theaters were opening with Dolby Digital built-in. Nearby in Chula Vista, CinemaStar opened early in 1993 was a tenplex and advertised ALL of their screens were THX & Dolby Digital - that's nearly a dozen in one shot. Quote:
Toy Story 2 was Disney's first feature in Dolby Digital Surround EX (6.1 with a matrixed rear surround). Toy Story 3 was the first film in Dolby (Digital) Surround 7.1 Brave was the first film in Dolby Atmos (despite only having a Dolby Surround 7.1 logo in the credits). |

So even prior to say CDS when it was Dolby Stereo or a 6 track mag playback for a special 70mm release like in the 1980s, a 6 track mix was the original mix and down mixed if needed? Or was that mentality more when digital was a possibility? Basically, for a movie that wasn't shot in 70mm but released in a blowup (let's say, BTTF part II ) was it originally mixed 6ch and then theaters got Dolby Stereo for 35mm and a select few got the OG 6ch, or was the mindset to mix for LRCS because that's what 99% if people would listen to with the 6ch 70mm blow-up being a special bonus? Also thanks PeterTHX for your post as well! |

6ch is a precursor of 5.1 in the sense that it has more discrete channels both front and surround, but the configuration changed over the years. Early ones had 5 front channels so dialogue, SFX etc could pan from one part of the screen to the other smoothly and had a single mono surround. No dedicated LFE. Star Wars and a bit earlier Sensurround I think introduced some LFE tracks, I think it was called "baby boom" at the expense of some of the front channels. Others used split surround. I'm not an expert in the 70mm mixes and how they progressed but that's a general answer to your question. IMAX 15/70 used an interlocked 16 or 35mm mag coated film in 6ch for playback as the format had no room for a soundtrack, no dedicated LFE and I think 2 rears and that configuration carried to digital sound with 15/70. Never heard the analog playback, IMAX digital is the best sound system I have heard to date so the lack of dedicated LFE is not a concern to me I think ![]() Modern 70mm prints use DTS now.

In the digital era of the 90s, it was at a much faster adoption rate. By 1994, most of the studio films were being mixed 5.1. It was only the independents really that were mixing in matrix surround by that time purely out of cost. |

Yeah, I ain't no expert but 5.1 became the standard at the source level pretty darned quickly. This is why I just couldn't get outraged over the 'missing' 2.0 audio on Arrow's Wild Things like that other dude did, that flick would've been 'natively' mixed in 5.1 (maybe even more if full-fat SDDS?) and so the 2.0 was more of an afterthought even at that early point. That's in contrast to the analogue multi channel era where separate mixes were still made for separate formats so for anything made before, say, 1990-ish then I still see real value in including the matrixed 2.0 as well as whatever else. Some mixers did regard the 70mm 6-track as their primary, there's a bit in AmCin with the sound mixer on Lynch's Dune (it's in the Arrow booklet I think) and he tears the matrixed stereo a new one whilst praising the 6-track to the heavens.

![]() 2-track optical was just so limited compared to magnetic 6-track. Some features in the 70s didn't even bother with a stereo version, they made a 70MM six track and a mono and that's it. 1941 was one of those I believe. |

It's more the pre-digital era where you'll have to work a lot harder to convince me that there's no artistic merit to the 2.0 mixes when a 6-track was available. Seeing as the split-surround config was still rarer than the Format 42 baby boom then most 70mm mixes were still LCRS, just a discrete mastering thereof. Some did still prefer it, no question, but if you said I have to have an OG 2.0 or nothing at all for whatever DS/6-track era movie then I'd take the 2.0 every damned time. A discrete rendition of the 6-track in a 4.1 or 5.1 container would be even betterer but I'll never renounce our lord and saviour 2.0 on pre-digital 5.1 flicks.

Watched the new Dracula 4K disc last night -- it was great.
On a side note, all this talk about when these new codecs were implemented and whatnot, I still remember the SDDS track for From Dusk Till Dawn and how reference quality it was. I saw that film like 5 times in theaters with different people and it was one of the best movie going experiences ever. /as you were |

There's no 6-track optical. 70MM 6-track from the Dolby-era (1976-1990s) used magnetic stripes on 70MM prints, blowups from 35MM originals, to have discrete sound with full frequency and higher dynamic range than optical Dolby Stereo (Dolby Surround) soundtracks. The channels were Left (L) Center (C) Right (R) Surround (S) and 2 "baby boom" bass channels in what was the left-center and right-center channels in the 1960s (trivia: SDDS 8-channel restored those extra center channels). Some call this configuration 4.2 In 1978 Dolby experimented with adding stereo surrounds to 70MM prints with Superman: The Movie - making the configuration 5.1 (LCR and LS/RS & sub) and in 1979 rolled it out officially with Apocalypse Now. Not too many films received the 5.1 treatment, most 70MM blow-ups in the 1980s were 4.2 - in 1986 Dolby added SR noise reduction for even greater dynamic range that exceeded 16-bit digital, Star Trek IV: The Voyage Home was the first film in 70MM SR. There are peaks in Indiana Jones and the Last Crusade that are like this. Since the 70MM blow-up process and prints were pretty expensive, not to mention most cinemas were scaling down to your typical multiplex size and so didn't have the room for 70MM projection equipment they set about working on a 35MM sound format that would do away with the limitations of optical soundtracks. In 1990 they introduced CDS, which ironically enough only went out at first on 70MM prints with Dick Tracy and later in 35MM. Problem with CDS in 35MM there was no backup track so if the digital track became corrupted or the decoder malfunctioned there was no sound, plus studios had to keep dual inventory of print types. Dolby was working on their HDTV transmission format at the time and realized they could encode their AC-3 format in between the sprocket holes of 35MM prints so technically you could make an entire print run Dolby Digital with standard Dolby Stereo as well. The format was 5.1 and had the dynamic range of 70MM. In 1993 DTS and SDDS were also introduced. Needless to say, the end of 70MM prints as a mainstream release format came to a quick end. |

Also, as I've pointed out, the 2.0 on this new UHD has a different music cue for the final scene than any other track I've ever heard for this film (including the Columbia Tristar laserdisc, whose audio was supposedly taken from the standard Dolby Stereo track). So I'm still not sure what's going on there. Quote:

The biggest advantage of having discrete channels is more fluid panning and no smearing. No dialogue bleed through to the low frequencies, which could be a big problem with the optical versions. Dynamic range, mag was more forgiving.
Optical was very unforgiving on loud peaks and would go straight to distortion, even at the printing stage. The QC back in the day for optical was so bad, that finding any track now without an issue is like winning the lottery. Distortion on mono and phase and misaligned channels on stereo are the most common. People really have no idea how good they have it today. Take for instance something like Halloween in 1978-79, it played optical mono with a frequency response at: 45-8000 Hz with the dynamic range at: 48 db. Nails on a chalkboard is the best way to describe that experience by todays standards. Apocalypse Now in 70MM 6-Track for myself is the gold standard. I was blown away and it was literally life altering for myself hearing that at a screening almost 30 years ago. None of the video releases including the Atmos mix sound as good in my estimation. The dynamic range and warmth of that mix was incredible and sadly it has been watered down over the years via new remixes, it's just not the same. Alien 70mm 6-track was terrific and that has survived it's port to video, the BD pretty much sounds the same. Predator is far superior in it's 6-track format. The low end was rolled off considerably in it's original theatrical matrix version. Once again, it sounds pretty much the same on BD/UHD. I restored the 70mm 6-track for the film The Entity, (1983). It really was a restoration, rather than just a remaster. Fox had lost the elements and only had a Spanish language 6-track in their possession in the US. I had to source out a Pal master that was made in Europe of this mix and that copy was literally deteriorating. One of the hardest things I ever did up until Black Christmas of course. The fact I was able to retrieve the audio underneath the garbage was a small miracle. What is interesting about that mix is that it features a lot of discrete panning for effects that are just completely lost in the 2.0 version and since the 5.1 was an upmix from the 2.0 print master it loses even more in comparison. Stuff that should pan to the surrounds are locked into the front left and right on the 5.1. I was glad I pursued this track, because it was 2019 right before the Disney takeover at Fox and I knew it was now or it is lost forever. Back to Dracula though, it is in my mind still one of the best 5.1 mixes ever done. The editing and panning is just insane in this mix especially for the time. A standout moment is Harker's arrival at the passage by coach and it's departure, which is a directional pan on the one side. Nothing had ever been mixed like that before with so much fluidity and directionality to the panning and it directly showcases the advantage that multi channel mixing could achieve over matrix surround. it's one of the moments that definitely earned it the Oscar. |

There were several attempts at stereo or multichannel audio over the years before 70mm's six track system was pioneered by the Todd AO format. When the widescreen revolution began in the 50's stereo and multichannel were a part of many systems but theaters were reluctant to also upgrade sound in addition to changing screens and entire halls.
Cinerama not only spawned the revolution in widescreen but in multichannel audio as well. Todd AO was the originator of the 6 track setup that became standard in 70mm roadshows. Equally important was Cinemascope having 4 track magnetic stereo which remained in use for a while and some films had 4 track mixes in addition to mono for general release. Also magnetic stereo or mag optical could be used in general 35mm runs meaning in capable theaters with magnetic prints some films could have beefier mixes or presentations available and it didn't have to be a 70mm blowup. As far as I know magnetic audio on 35mm prints lasted up to Scarface in 1983.. In the digital sound era just because 5.1 was suddenly available didn't mean it took over overnight. Most films were still mixed and released with SR in mind if not entirely if you look at lower budget films and the emerging indie market. It really depends on the sound team. Going on a film by film basis and 90's studio practices by a certain point digital sound had taken over the sound world but it was up to theaters to purchase, install and implement correctly. SR-D as Dolby first called 5.1 ac3 was backed by some studios, DTS by others and SDDS was Sony's baby. Depending on the studio and licensing eventually combo format prints would turn up carrying multiple formats. As far as I know in regards to Bram Stoker's Dracula there was a multichannel sound master and two mixes were then done: one for the 6 channel 5.1 master and the other for the general release 2.0 SR. A number of music cues and effects are supposed to differ between them and the two main Laserdisc releases were specifically sourced from the alternate masters. Prior to the modern remixes I thought Sony had seemingly offered different versions of the 5.1 master. |
