Widescreen Review with all due respect has zero credibility.

IMO IMAX enhanced is just a way for DTS to re-gain some market share its lost since Dolby Atmos and Dolby Vision have taken over the the 4K market.

That is how it appears to me as well. They definitely have an uphill battle.

Yup.


Never get over his bias.
When several of the first DVDs came out from Image Entertainment, several were mismarked "PCM 2.0" instead of the Dolby Digital 2.0 they actually were on disc. The reviews for the correctly marked DD 2.0 were all "muddy and inferior to their LaserDisc PCM counterparts" where the mismarked as PCM discs were lauded as sounding "identical to their LD counterparts" - even though they were really DD 2.0 as well.

So a month later and we know nothing about any forthcoming discs...

[sapiendut]

Well, there is no substance to it. I’m still waiting for the IMAX Enhanced version of Venom UHD BD to be announced and released.

[Geoff D]

This is still a thing? Lol

Yes

No

In defense of DTS, they weren’t jacking up rears and bass dilly dally. They know most of the listeners don’t listen at reference level so they jack up the rears and LFE as per psychoacoustic calculation how the hearing frequency response respond at -20 dB off reference.

It's still "cheating" making people think their soundtracks had more bass & surround.

Not that I'm defending them either, but they didn't "jack up" the tracks, they just left the channels at theatrical levels and didn't lower the surrounds or LFE to industry home level standards.

[sapiendut]

If people arw stupid enough not to realize that the levels are different than DD, is it DTS fault?

[eddievanhalen]

Cheating or no cheating I had the US Dolby Digital Jurassic Park Laser Disc and a friend of mine had the DTS one and the DTS Laser Disc of Jurassic Park trounced the Dolby Digital one. It wasn't just bass or more rear sound, there was a sense of space and ambiance that the Dolby Digutal track on the LD lacked.

I had the DTS laserdisc as well and I agree... probably the most bass intensive version of JP yet. Tight and dramatic. Dishes would fall out of the cabinets. Earth shaking. And there was depth to the sound. The T-Rex sounded BIG and scary.

It's the new HDR 10+, it'll limp in eventually.

The other day I saw a billboard for IMAX Enhanced while driving down the freeway. I don’t ever recall seeing a billboard for THX, DTS, etc. No deep meaning. Just an observation.

The sense of space is due to the boosted rears and sub, actually.

Cheating or not, it works. It sounds better overall. That’s all that matters in the end.

Also DTS on laserdisc was far less compressed than RF modulated Dolby AC-3.

[sapiendut]

Not necessarily less compressed. Larger file size? Yes, but that’s because DTS codec was a lot less efficient than AC3 codec.

AC-3 at the time on laserdisc was 384 kilobits/sec with heavy use of psychoacoustic compression. DTS Coherent Acoustics was ~1.4 Megabits/sec.



We're not talking about Dolby Digital Plus at 640 kilobits/sec or greater, which never showed up on laserdisc.

Because it was a highly inefficient codec. People don't consider MPEG2 video superior to AVC now do they because it requires super high bitrates in comparison? Also, Coherent Acoustics was a codec they bought. DTS has yet to create an in-house codec completely. DTS theatrical is based on APT:X. DTS:X is SRS MDA modified.

All RF-modulated means it dumps the entire signal and must be filtered out by an RF-modulator. Nothing that makes the signal less quality.

Because the LFE channel was jacked +10dB

+3dB is double the loudness (the surrounds). +10dB is ten times the level it was supposed to be. The Dolby Digital version was accurate to the source.
