The Lionsgate logo on most DTS Lionsgate titles is at 96K as is the Blu-Ray "Leon the Professional" 96K.
Got it. Thank you! Very exciting news!Ronald Epstein said:Osato,
We don't know DTS' plans. This is something that Dolby is doing that we
hope will revolutionize the industry. I would assume their plan is to provide
a new audio format that exceeds and replaces DTS-MA.
So, presently, the answer is no -- DTS MA is not at 96k. Will they try to
play catchup? Perhaps. However, it is my belief that Dolby has the perfect
storm of audio perfection and supportive tools that will make it difficult for
the studios not to widely adopt this new format for future releases.
Pretty much, at this point, we are quite excited, but basically sitting on
the sidelines to see what happens next.

I take it this is Dolby's way of getting a leg up on DTS? Because currently DTS-HD Master Audio Blu-rays far outnumber Dolby TrueHD Blu-rays. Maybe future releases will swing in the other direction.
It is no big deal to most of us who wins the market share wars between Dolby and DTS. We just want the best sound from our systems. That said I'm sure that to reap the full benefits of the new Dolby system AND the DTS 24 bit/96kHZ system (don't believe it has been utilized for movies as yet) one will be required to update their system. That is not the same as saying this new codec will not sound better on your present system its just that one will have to purchase new equipment or upgrade(when available) to hear the new 24/96k codecs.Toddwrtr said:The main reason, imo, that DTS has been able to grab major market share on Blu-ray is because DTS-HD is backwards compatible, while Dolby TrueHD is not. Thus, only one soundtrack is required on the disc for DTS-HD, while discs with TrueHD will still require a separate lossy track for compatibility issues. This not only makes the authoring process much simpler, it also, potentially, saves on disc space.
I'm not sure what you are using currently Paul, but odds are if your BD player and or receiver can decode Dolby TrueHD now, then you won't have to purchase new equipment. They aren't changing the codec, just improving the way they encode the audio.Paul Rossen said:It is no big deal to most of us who wins the market share wars between Dolby and DTS.

I have a Pioneer 320 player and a Theta Casablanca 111HD with their 'extreme' dacs in all channels. I believe that Theta is upgrading their dacs to play at 24/96 but that will be very expensive and I'm about 'through' upgrading my Casablanca unless I get a really good deal.(I started with the Casablanca1-regular dacs). The unit will of course play Dolby HD as well as DTS Master Audio. That said I don't believe it goes to the 96k.Adam Gregorich said:I couldn't agree more. For now there is no way to compare 48k to 96k. We were able to do it through some clips that they assembled for us. Ron and I were both clear that they need to have a demo disc or a featurette for consumers to be able to compare for themselves that there is a difference, because there is. Frankly I wouldn't have believed it if I didn't hear it for myself. It just would have been another buzzword on the box.

Todd, another big reason for the market share difference is Dolby's authoring and encoding tools have been frankly, pretty crappy in the past, where DTS has had some great ones. Dolby is releasing a new version of their Media Producer in the next few weeks that not only adds the Advanced 96k but also really simplifies the process and is pretty easy to use.
I'm not going to say audio is equal to video in importance to me but I enjoy a good track. In my system, Dolby True HD has always sounded better than DTS-HD Master Audio, even though they should sound the same. The surrounds seem more directional and active, and the overall sound seems more distinct. Many people seem to prefer DTS, but I look forward to more Dolby True HD tracks possibly now.Jeff Adkins said:This sounds great to me (no pun intended). I'm glad to see that Dolby has upped the game in regards to Home Theater sound. To me, the audio has always been right up there with video in terms of importance to the overall movie-viewing experience at home. This is a win-win for the consumer. I remember just a few years ago, many people were saying Dolby Digital Plus was "good enough" and lossless was just "overkill" and that we'd never hear the difference. I'm excited to hear this new 96K process.
Thumbs up Dolby!
The problem is for the most part the cinema supply chain is set up to deliver 48k. Thats not something that is easily changed.Originally Posted by John Stockton /t/320815/breaking-news-dolby-truehd-elevates-the-quality-of-lossless-audio-on-blu-ray-must-read/30#post_3927211
Besides Leon the Professional and Sex Lies and video tape, Akira is another title which has the distinction of having a Dolby tru HD 192 KZ sampling. Although I like what Dolby is doing I wish they would concentrate more on having the studios bring us genuine 24 bit 96 Kz or 192 Kz rather than this upsampling from 48 Kz process.
Just to expound on what Adam said, this was one of the first questions Dolby was asked - and it was explained by James Spezialy (who worked at Warner for 13 years) that it's a technical limitation on the studio's side that keeps them at 48 kHz. In this case, Dolby is helping to solve a problem that won't solve itself for at least several years.Adam Gregorich said:The problem is for the most part the cinema supply chain is set up to deliver 48k.

At what volume level does this preringing occur in relationship to the peak signal? 50dB below? 70 dB below? I'm willing to bet that any preringing artifact exists miles below the noise floor of even the quietest living rooms. (Unless you listen to your blurays at volumes beyond the level of a fighter jet engine!)SineDave said:Dolby's engineers were confident you could hear a difference regardless of the gear reproducing things - and that seems to hold true given the nature of the improvement - it's not upsampling per se that improves things, it's the apodising filter that cleans up the attack by reducing pre-ringing.
That's the Achilles Heel of all upconversion schemes.Chuck Anstey said:From the press release and discussion this seems pretty straight forward. Dolby is looking at 48KHz masters for certain artifacts that don't exist if originally recorded at 96KHz. They filter the artifact with a "better" guess as to what it should have sounded like (or simply remove it altering the sound) and the re-encode at 96KHz. The video equivalent is the difference between encoding in MPEG2 vs VC-1. MPEG2 has certain artifacts that are greatly reduced or eliminated if using VC-1. So the way to improve an MPEG2 encoding is to analyze the video for certain digital compression artifacts, filter them to make a more artifact free image, and then re-encode in VC-1. Of course this will result in an inferior result compared to going back to the original uncompressed images and encoding with VC-1 from the beginning but it will have fewer compression artifacts than the MPEG2 encode.
