Movie was ok. Acting was a bit meh, maybe that's why the imdb score was only 6, otherwise it's perfect for the family.

Just watched the movie, you can definitely tell when that 14Hz moment hits, christ

That is an interesting graph. I don't know if I should be excited because it goes almost all the way to 0 horizontally but the green line is not very high so not as dynamic, correct?

It's an infamous scene in the basshead community, when the command "Irene" is given, and some helicopter blades output a strong 6Hz signal, that's about it

Netflix plans to improve audio in streams

I can't believe no one has commented on Netflix's plan to improve the audio of their streams. Especially those of you to have 7.2.4 configurations. I thought there'd be more "buzz" about it by now. Must just be me.

If you’ve suddenly noticed improved sound in the midst of your latest Netlix binge, thank “Stranger Things” creators Matt and Ross Duffer. Starting today, the online streaming giant has rolled out “studio quality sound” on its platform by bumping up the bitrates by which audio is delivered, all with the intent of creating a “magical combination of sight and sound [that] brings viewers closer to the story.”

So Netflix upgraded to the supposed quality and bitrate of a compressed secondary track on Blu-Ray disc (Revolutionary) Haha. And it isn't constant but variable based on the wording below.


"Per Netflix, depending on your device and bandwidth capabilities, the bitrate you receive may vary:

5.1​: From 192 kbps (good) up to 640 kbps (great/perceptually transparent)

Dolby Atmos:​ From 448 kbps up to 768 kbps (Dolby Atmos is available for members subscribed to the Premium plan)"

Here is the techblog detailed info from Netflix.

Quote:
ur high-quality sound feature is not lossless, but it is perceptually transparent. That means that while the audio is compressed, it is indistinguishable from the original source. Based on internal listening tests, listening test results provided by Dolby, and scientific studies, we determined that for Dolby Digital Plus at and above 640 kbps, the audio coding quality is perceptually transparent. Beyond that, we would be sending you files that have a higher bitrate (and take up more bandwidth) without bringing any additional value to the listening experience.

In addition to deciding 640 kbps — a 10:1 compression ratio when compared to a 24-bit 5.1 channel studio master — was the perceptually transparent threshold for audio, we set up a bitrate ladder for 5.1-channel audio ranging from 192 up to 640 kbps. This ranges from “good” audio to “transparent” — there aren’t any bad audio experiences when you stream!

At the same time, we revisited our Dolby Atmos bitrates and increased the highest offering to 768 kbps. We expect these bitrates to evolve over time as we get more efficient with our encoding techniques.
TDLR; they are using the same adaptive video technique on audio now and boosted the top bit rate.

Nothing announced, it's just their streams changed 9 months ago, as noticed by those who voyage the high seas, so to speak...


Quote:
Previous Bitrates:

EAC3 5.1 @ 192K
EAC3 Atmos @ 448K
AC3 5.1 @ 384K

New Bitrates:

EAC3 5.1 @ 640K
EAC3 Atmos @ 728K
AC3 5.1 @ 384K

AC3 Elementary Track Bitrate has stayed the same.
The adaptive bit might be new on the audio side, but I dunno

Avengers: Endgame (2019)

Quite surprisingly, it was a much better sonicl experience than Infinity War and Ant-Man 2 with quite a few very, very nice bass moments that took me by surprise. One of those moments literally had my pants flapping, something I don't think I had experience at the theater before. I felt the audio levels were on the lower side, but at least there's hope the home release could be quite good.

Compared to the bass monster that's Aquaman, this latest Marvel flick is on the moderate side, but I can say I wasn't disappointed on the audio department, and overall I was pleased with the sound, but I should point out my expectations weren't very high. Those who felt that Aquaman was quite heavy handed with the bass may find the use of bass in Endgame more of their liking. I found the use of bass very appropriate and well done in many scenes, which was a nice surprise.

Apocalypse Now 40th Anniversary 4K Blu-ray

https://www.blu-ray.com/news/?id=25025

  1. NEW 4K RESTORATION OF THE FILM FROM THE ORIGINAL CAMERA NEGATIVE
  2. DOLBY VISION HDR PRESENTATION OF THE FILM
  3. DOLBY ATMOS TRACK/Sensual Sound enhanced

Apocalypse Now re-released with Meyer Sound Sensual Sound technology


Sensual Sound is implemented in both the post-production of the soundtrack and in
the film’s exhibition using Meyer Sound’s VLFC very low frequency control element.
Unlike conventional subwoofers that roll off at the threshold of hearing (about 20Hz),
the VLFC bridges across this threshold to deliver infrasonic response down to 13 Hz.
All very low frequency sounds are bolstered by a corporeal sensation of physical force.

With all that "sensual" audio marketing PR jargon involved with Apocalypse Now, it would be hilarious if we generate a bass graph and find out its been neutered like other movies!

Is It safe to assume no new gear is needed to take advantage of this new tech?

Cool!

Could have really used this “Sensual sound” touch with the Alien 40th anniversary UHD remaster. Audio was great for what it is, but zero bass to be had...would’ve added a lot of palpable tension to one of the best classic sci-fi horror movies of all time.

If it had any more palpable tension, I'm not sure the local emergency rooms could have handled the resulting cases of cardio-vascular distress. Just sayin', be careful what you wish for.

You just need subs capable of output that low. It's just code for "we didn't neuter the ULF in this release"

I do remember something about under 10Hz can kill you. Interesting article, https://science.howstuffworks.com/ca...-wave-kill.htm

There’s no bass even with BEQ for Alien, it’s a black chasm below 40Hz judging by the spectrum graph, so I didn’t even bother applying it. There is a little midbass to be had though.

Here are some really cool key points from that article...

Humans can only hear sound waves between 20 and 20,000 Hz, but sound waves can still affect us below that threshold. If you sit in front of a subwoofer with the frequency at 19 Hz, even with the volume turned up to 100 dB, you won't hear anything — but you'll feel the vibrations. In fact, at 19 Hz, your eyes start to go all wonky because that happens to be the resonant frequency of the human eyeball. If you're exposed to 177 dB sound waves at 0.5 to 8 Hz, it can start messing with your lungs, making your breathing erratic and literally shaking your bones around. Short-term exposure can damage your joints, but the effects of chronic exposure can include nausea and visual impairment [source: Horowitz].

The European Space Agency (ESA) claims that if you somehow got accidentally locked inside their Large European Acoustic Facility (LEAF) for testing the acoustic resiliency of their satellites, you wouldn't survive the sonic onslaught. A key factor here is that you'd be in an enclosed space. Outside, sound waves disperse and dissipate too quickly to reach lethal levels. That hasn't stopped researchers from investigating the use of sound as a weapon. It's been calculated, for instance, that it would require 240 dB to make a human head explode. That's a whole lot of decibels. It would be next to impossible to generate this level of noise. Even when the ESA's LEAF cranks its sound up to peak intensity, it's only putting out around 154 dB [source: ESA].

But for non-lethal purposes, sound weaponry can really come in handy. Say, for instance, you want to dissuade a boatload of Somalian pirates from joining your cruise. Try turning on your trusty $30,000 long-range acoustic device (LRAD) and hammering them with a beam of 150 dB of bone-jarring noise, which can cause permanent hearing loss for its targets even at distances of 1,000 feet (300 meters) [source: Blenford].

I recall the Alien laserdisc AC3 has deep bass. Wil have to play it when i free and report back.

Any of you out there going to the crazy awesome AV trade show Infocomm here in Orlando? I'll be there.

Humans can only hear sound waves between 20 and 20,000 Hz, but sound waves can still affect us below that threshold. If you sit in front of a subwoofer with the frequency at 19 Hz, even with the volume turned up to 100 dB, you won't hear anything — but you'll feel the vibrations. In fact, at 19 Hz, your eyes start to go all wonky because that happens to be the resonant frequency of the human eyeball. If you're exposed to 177 dB sound waves at 0.5 to 8 Hz, it can start messing with your lungs, making your breathing erratic and literally shaking your bones around. Short-term exposure can damage your joints, but the effects of chronic exposure can include nausea and visual impairment [source: Horowitz].

The European Space Agency (ESA) claims that if you somehow got accidentally locked inside their Large European Acoustic Facility (LEAF) for testing the acoustic resiliency of their satellites, you wouldn't survive the sonic onslaught. A key factor here is that you'd be in an enclosed space. Outside, sound waves disperse and dissipate too quickly to reach lethal levels. That hasn't stopped researchers from investigating the use of sound as a weapon. It's been calculated, for instance, that it would require 240 dB to make a human head explode. That's a whole lot of decibels. It would be next to impossible to generate this level of noise. Even when the ESA's LEAF cranks its sound up to peak intensity, it's only putting out around 154 dB [source: ESA].

But for non-lethal purposes, sound weaponry can really come in handy. Say, for instance, you want to dissuade a boatload of Somalian pirates from joining your cruise. Try turning on your trusty $30,000 long-range acoustic device (LRAD) and hammering them with a beam of 150 dB of bone-jarring noise, which can cause permanent hearing loss for its targets even at distances of 1,000 feet (300 meters) [source: Blenford].
