Online Movies Audio Face-off, Pt. 2

Online Movies Audio Face-off, Pt. 2

In Part 1, I wondered if you could hear any differences in Dolby Atmos surround sound on the various movie streaming services and movies downloaded from Kaleidescape, and decided to do a comparison between Vudu, Apple TV, and Kaleidescape to find out.

 

After an afternoon of listening tests, here are my results.

 

I have a pretty high-end audio system, consisting of the new Marantz AV8805 flagship preamp/processor, two Marantz seven-channel amplifiers, and a 7.2.6-channel speaker configuration that includes Definitive Technology Mythos ST-L tower

speakers, a Definitive Trinity Signature Reference sub, and an SVS SB-16Ultra sub. I watched all of the movies at the same volume setting: -15 dB.

 

For source material, I used my Kaleidescape Strato to handle the Dolby TrueHD audio on movies downloaded from the movie store, a Microsoft Xbox One S to stream content from Vudu, and an Apple TV 4K to play movies from the Apple Store.

 

I mined my movie collection to find multiple titles I owned across all three services that featured Dolby Atmos soundtracks. This allowed me to cue up the scenes on all three devices and fairly quickly listen to each scene in the different formats.

I watched a number of scenes from six films I’m familiar with: Ready Player One, Baby Driver, Blade Runner 2049, Gravity, Venom, and Jumanji: Welcome to the Jungle. After A-B-C’ing each scene multiple times, I can definitively say two things: 1) the TrueHD audio mix always sounded better, and 2) audio from the Apple TV 4K sounded substantially quieter and more compressed.

 

By far the most readily noticeable audio differences were in the low frequency range. Consistently, film after film, scenes with low-frequency activity were far more dynamic and impressive in TrueHD. The low end had more physical impact, producing frequencies I could feel, as well as pressure waves that rattled doors and windows.

 

The opening “Bell Bottoms” scene from Baby Driver is a perfect example, where the bass notes in the song were thin and indistinct with the Dolby Digital Plus (DD+) on Apple TV and Vudu, and the shotgun blasts had little weight. With TrueHD, the bass was articulated, and the shotgun plumbed far lower and louder.

 

The bass-heavy Blade Runner 2049 also offered multiple scenes that showcased the superiority of the TrueHD soundtrack. The pistol Deckard uses in his fight with K in old Vegas had far more impact, as did the rushing water, thunder, and air vehicles flying at the pump station. The fantastic Benjamin Wallfisch and Hans Zimmer soundtrack also sounded richer, producing notes that were more musical and real, with better tone and decay.

 

Textural sounds also had far more dimension and realism with TrueHD. The first challenge race from Ready Player One was a perfect example, featuring a lot of different vehicles with unique-sounding engines. The multi-layered sounds of the engines, crashes, crunches, and explosions had more detail and separation, being less distinct in the DD+ version. The motorcycle chase in Venom exhibited this same sonic loss in DD+, as with the sounds of the drones flying, or the details of bullets striking. It was similar with the crunching and thrashing from the hippo attack in Jumanji.

 

As mentioned above, the audio levels on Apple TV were significantly lower across every film—often 10 dB or more. This was obvious on everything, but especially noticeable on Gravity, where the opening dialogue chatter between Stone and Houston was virtually inaudible, making it completely unintelligible when played at the same levels as the Vudu and Kaleidescape versions.

 

Even with volume levels raised to compensate, the Apple versions of the films just seemed far more compressed, lacking dynamic range. This was similar to what I experienced on the Taylor Swift Reputation Stadium Tour streamed from Netflix, making me wonder if there is some issue with the way the Apple TV 4K handles Atmos audio. 

 

Now, while the TrueHD mix was definitely better, that doesn’t mean the streamed mix was bad. Just not as good. This was especially noticeable when played back to back, where the TrueHD audio had a wider, airier, more natural presentation. Outdoor scenes like in the jungles of Jumanji just felt more open and like you were in the actual environment, while the DD+ audio felt more centered on the screen.

 

For luxury cinema owners who’ve invested in getting the best experience possible, there are definite, noticeable audio improvements to be had by purchasing content in the lossless format.

Demo Scenes: Baby Driver

Demos to Die For: "Baby Driver"

The demo scenes featured in this series of posts are perfect for putting a showroom system through its paces, making sure your new entertainment space makes the grade, or showing friends what your system is made of. Baby Driver is a go-to title for showcasing a luxury Atmos system (see “Why You Have to Have Dolby Atmos”). It’s available on Ultra HD Blu-ray, for download from the Kaleidescape Movie Storeand from streaming services like Vudu and iTunes.

Using R-rated content for demo material is a very slippery slope since it can easily be off-putting to many viewers and obviously isn’t suitable for families. And the

Demos to Die For

most demo-worthy scenes from R-rated films usually contain gratuitous violence, profanity-laced dialogue, and nudity that can quickly turn showing off your system into a turnoff. But these two scenes from Baby Driver are terrific exceptions you can show to any audience without fear of offending.

 

Both scenes show off the strengths of Dolby Atmos object placement and tracking capabilities—so make sure you have the HDR or UHD version of the film so you can enjoy the Atmos audio.

 

Scene 1: “The Bellbottoms Bank Job”
(0:50–6:25)

 

This scene is an absolute grand slam, checking off nearly every box for “What makes a great demo?” It’s literally the opening of the film, so you not only don’t spoil anything for people who haven’t seen it before, you’ll likely hook them to want to see more. It’s a complete story in itself, with a clear beginning, middle, and finale. And, it’s action packed, with some of the best driving you’ll see on screen, with a fantastic accompanying audio track.

 

One of the brilliant and innovative things about Baby Driver is how director Edgar Wright used music to propel and choreograph each scene. This opening plays loud and proud from the overhead speakers, with vocals that swirl around the room, and features a sub-heavy bass line that drives the tempo.

 

Notice how Jon Hamm’s shotgun blasts fire in time with the music. A potent and well-calibrated sub will have you feeling the Suburu’s engine revs in your chest as Baby pushes the WRX to its limits. As he drifts around the city, you’ll clearly hear tires squealing and protesting the physics-defying maneuvers, with the audio tracking every siren, horn honk, and car that whizzes by. While video isn’t the focus of this demo, notice the stoplight colors, with vibrant yellows and reds that push the color-space boundaries.

Scene 2: Opening Credits/“Harlem Shuffle”
(6:25–9:09)

 

This scene couldn’t be easier to find since it begins right after the first demo scene ends.While the first scene is all about excitement and bombast, this one is just Baby walking to grab some coffee before heading to meet his crew. Notice how amazingly the audio tracks the off-camera action. You’ll hear an infant cry far off camera left, and then see a mother with a stroller pass Baby. Throughout, the audio swirls relative to Baby’s perspective and position, with the sounds of traffic, conversations, and jack hammers announcing their arrival long before they appear on screen, and long after they’re no longer in view.

 

Also notice how the audio changes when Baby walks into the coffeeshop. When he pulls out an earbud to hear the barista, the music volume drops and the sounds of the coffeeshop fill the room, with the music taking over as he replaces the earbud. This entire scene displays how a terrific audio mix along with properly placed speakers can transform a media room into an entirely different environment.
