DTS Headphone:X Makes Debut with Man of Steel Score - Page 6

post #151 of 182
On the bright side, there's another update to the z+ app coming, apparently this week sometime. Support wrote back to me to say they've identified an issue within and have submitted a fix that should be available shortly. Touch wood I can actually download some of these tracks when it goes live.
post #152 of 182
I've got all my tracks downloaded on the original key I was given even though I was given a replacement key (when I asked)--not sure if they fixed the server issues or the new iOS app version helped. Not sure why they are giving out new keys if that isn't the core issue, but I'll hold on to mine so I get at least one do-over for free when the DRM inevitably bites me one way or the other (hardware lost, swap, etc).

re: "This technology encodes audio files with up to 11.1 channels and simulates what you would hear from a corresponding speaker array using any pair of conventional headphones"

I thought the whole point of HRTF/binaural audio with headphones was full 360 degree spherical soundfield, i.e. totally arbitrary apparent location/distance positioning of any sound "outside the head" of the headphone wearer.

Kinda silly to discuss a number of "speakers" or speaker array simulation in that case.

Yes, we know it's marketing-droid speak...

The positioning information has to come from somewhere...until there's a format that can contain arbitrary locations in 3D space, we'll have to make do with virtual channels.

New update is out, v1.11 I believe. iTunes description says it contains just minor fixes.

Tracks still download very slow for me, and they fail if my iPhone 5 auto-locks while its happening (had to turn that off to get anything), but on the bright side, the app at least remembers my having entered a code now when I shut it down and fire it back up.

I'll be honest though, while the 'front left' and 'front right' demo is impressive, I can't really tell the difference between this and just listening to what Ive synced across from having ripped my audio CDs. :/

Prereqs: iOS device, MoS Deluxe Edition with promo code, DiskAid (for mac or PC) or another iOS file manager. This does NOT require jailbreaking your ios device.

I confirmed that this works on an iphone 4S and an ipad mini using the mac version of diskaid.

Prep:
1-download the Z+ app
2-follow the instructions on the CD voucher to redeem the free tracks
3-once they're all downloaded, connect the device to your mac/PC via USB.

Backing up:
1-Create a backup folder on your hard drive (name doesn't matter)
2-Fire up disk aid, and navigate to Storage->Apps->Z+
3-You will see a "license.dat" file and a "Track" folder. Copy both of them to the backup folder. Size should be just under 450mb.
4-If you want to mess around with the files, I'd recommend making a copy and making a zip backup of the original.

Restoring:
1-Reinstall the Z+ app on any iOS device
2-Open it, and skip the demo until you get to the track list with the purchase buttons.
3-Close the app and quit the Z+ process (double click the home button, press and hold the Z+ icon, and press the red "-" button)
4-In disk aid, navigate back to the Storage->Apps->Z+
5-There should only be a "Tracks" folder containing the 30 second preview tracks. Delete the folder
6-Copy the "license.dat" file and the "Tracks" folder from your backup folder to the app.
7-Relaunch the Z+ app and your tracks should all be back like they were never gone.

It looks like this restore method works for any ios device regardless of whether that device originally downloaded the tracks. However, as with other copyrighted material, this method is only legal when used for backup, device shifting and other fair use. If you put the files on ********** and get caught, don't come complaining smile.gif

EDIT: haha, even the forum software thinks b1tt0rrent is a dirty word smile.gif


I can't find Storage anywhere on Disk Aid!
On the left side I can only see
Music and Vid
Photos
Data
Apps
File System

Please help me! smile.gif

Go straight to the apps directory, I think. My apps are listed in storage, but wherever apps are, the Z+ should be accessible from there. Here's a screenshot of how it looks on my system.

Hey guys

Anyone here with a rooted Android managed to locate the DTS tracks?
I've been searching all over the place with Root Browser but the tracks are nowhere to be found. But when I used TitaniumBackup to backup the app, the total file size is over 400MB, which means the tracks are hidden somewhere but I can't find it.

Any help here?
post #160 of 182
Okay, just an update. I managed to extract the files after backing up with TitaniumBackup on my rooted Galaxy S II, running CyanogenMod Nightly ROM. And I'm not sure whether to be pissed or upset or whatever.
It seems like the "Stereo" mode is nothing more than a m4a rip of the audio CD, but on Android, the "DTS" mode are...lossy OGG files??

Based on "JD NC"s screenshot, on Apple iOS, the DTS files are properly encoded in DTS with the .dtshd extension.
But on Android, I think they're encoded in .ogg files. Maybe this explains why it was so difficult to extract the files in the first place

So, if I'm not wrong, when you switch between "Stereo" mode and "DTS" mode, it switches between the .m4a track and the .dtshd (on iOS) or .ogg (on Android)
And the DTS track is really the "Over Ear" track, while the "On Ear" and "In Ear" track is some sort of filter or EQ setting applied to the .dtshd/.ogg track.

Gosh! I can't think. I feel ripped! I would have used the voucher on my iPod, but my iPod is too weak that it causes the music to start skipping.
I am disillusioned right now.

I'm seem to a bit confused, or is it 'out of date'? When did we lose the centre-back channels? Have these been replaced by rear heights?
post #162 of 182
It may be a silly notion to sit in the middle of an orchestra during a performance, but until you have been there, you shouldn't knock it, it's a very different exposure and what a lot of fun it is.

As a frequent attendee of dance halls in the fabulous days of rock-n-roll in the 60's through to the 80's, watching and listening to vast numbers of musicians (good and bad) hammering out their beats, and as a rock musician (70's-90's), actually working on those stages, big and small, I can remember how great it was and how we didn't even think about where the other instruments were across the stage but relished in the discrete nature of it. We had surround sound before it was 'invented'. The audience got a 'wall of sound', but on stage we got it all around us, it was FANTASTIC. When I eventually downed the bass and went into mixing, it was back to the sound wall again, but with a much more discerning ear of course. I loved every decibel of it. So I am happy to sit in the middle of the theatre AND/OR the centre of the stage, it's fantastic fun either way, loud or soft. Luv It.

Rear center has been replaced by Rear Left and Rear Right.

Long ago, when Dolby and DTS were pushing for 6.1 soundtracks, both companies and THX recommended home theater owners to use 7.1 systems to create a balanced Rear Center channel. Where the Rear Left and Right outputted a mono channel.

6.1 lasted only for short while until about two years ago, when Dolby pushed for discrete 7.1 in cinemas.

I bought the man of steel cd tried to download the zplus but was told it had to be on a device (my ipad needs ios6 but I have the first ipad and it will not update to ios6 then I tried to download it to my iphone 4s and was instructed that I it was over 50 meg so I had to do it through itunes. So far I have not been able to do this itunes is not intuitive and I still cannot experience this 11.1 sound on my headphones. Can you help me ?
post #165 of 182
This sound track is turning out to be a dog, in terms of what it promised: DTS Headphone X with the possibility of running it through a home theater system. It is obviously meant for mobile devices and not serious home theater listening. Well, at least it came in a steel case. If there is an isolated 5.1 soundtrack on the BR, it will probably sound better than what is out there now. Too much hype without the goods. I seriously doubt that I will ever buy another promised DTS Headphone X soundtrack blindly.

In what manner do you expect a "serious home theater system" to improve the experience? Just curious. Is it the headphone jack?
post #167 of 182
The demo sounded very convincing. Given a little more time and opportunity, it could be an interim home theater solution for the new surround formats with height channels. Namely Barco Auro3D and Dolby Atmos.

Headphones cannot reproduce bass like a sub can.

But how does that apply to a technology that is meant specifically for headphones?

Where do you enter the code? Android Jellybean /Galaxy S4

Follow the step by step instructions.

Got it, thanks
post #173 of 182
I finally got 'round to installing this app and am terribly disappointed. I used a Note II and Sennheiser HD555s (closest I have to the 239s). After all the hype about precise imaging and source location I probably had too high expectations.

The stereo mix is awesome, but the multichannel mixes sound hollow and muddied to me and certainly not "enveloping". In the spoken-word demo, I can tell left and right apart, but I can't tell front and rear and up/down apart. Does that mean my HTRF is different to the one used to encode the music? In the interview, it sounded like the technology supports a way to load different rooms and to tweak the head transfer functions. I'd like to see this demo'd.

And here I thought we finally had a technology that'd let me listen to surround sound movies without disturbing the neighbours.
post #174 of 182
It is disappointing. I did manage to extract the files from the app and they turn out to be just ogg files on the Android version. I believe someone did extract the Apple iOS version and they were actual DTS encoded files, albeit lossy.

Buy I'm still willing to give this format a chance. I really hope to see this used on Blu-ray, with movies that had a Dolby Atmos or Barco Auro 11.1 soundtrack in cinemas.

That would be brilliant. But key for me is that you don't need a specially-encoded track. It could encode a normal surround stream (DTS or AC3) on-the-fly, so you could use it with all your existing blurays too. Except it doesn't seem to work for me :-/
post #176 of 182
I personally prefer a separate encode. It's kind of like Dolby Headphones, encode a 2.0 track specifically for headphones.

What we should have is a "DTS Headphone X certified" headphones. Pair it with a DTS Headphone X soundtrack to recreate the best 11.1 experience for home viewing.

I don't think this could ever work properly with a 2.0 track, because I think individuals will want to load different head and room transfer functions. So you want the underlying medium to carry the information, not the encode. I suspect the transform will need to be done in realtime if it's ever to work effectively. In this case, you could have 5.1, 7.1, 11.1 or XX.YY speakers simulated... it wouldn't matter.

Yeah, I'd support this, even if just so we could have a proper set of 'phones where its transfer function is properly characterised. Most manufacturers don't even provide frequency response curves with their headsets, let alone impulse and time-domain characteristics. I believe these things should be part of the standard specification sheet with any transducers.
post #178 of 182
Well, we were just talking about it, and now it's really happening.
Skullcandy Aviator looks like the first DTS Headphone:X headphones.
https://www.facebook.com/DTS.Inc?sk=app_143103275748075&brandloc=DISABLE&app_data=dlt-1

There's suppose to be two other products, from Panasonic and Republic of Gamers announced at CES, by DTS. But they may not necessarily be headphones. It could be something else. So I'm still keeping an eye out.
post #179 of 182
I just listened to the demos available for Android and well the audio clips are so so but that DTS Demo blows my mind away, very impressive, I honestly though my surround system was on and was like wait thats coming from my headphones. ^^;; I cant wait to see the full app to be released. smile.gif
post #180 of 182
I find it difficult to figure out what Headphone:X actually is, after reading through much of this thread. Is it a method for downmixing multichannel sound to stereo that is especially tailored to headphone listening? Am I warm?
I don't understand what is remarkable or interesting about that. If there were some customization of the downmixing to a particular listener's room or his ears, that might be new, but that doesn't seem to be part of it. So what is the point? Isn't it just a form of headphone stereo? Why should it take any special processing on the listener's end to hear it?
By the way, my Turtle Beach XP400 headphones, which downmix DD 5.1 to headphone stereo, do allow for some customization -- supposedly you can adapt them to your ears by fiddling with the virtual angles of the virtual 5.1 speakers you're listening to. (I haven't yet experimented with this feature.)
