Good multi channel music has been mixed to produce sound in different . neural X upmixing you hear him rolling around on the top of the car!. Friends and I liked DTS Neo:6 in my experiments with classical music, and I think Neural X is similar. I was less happy with various Dolby. The DTS Neural Surround UpMix, DTS Neural Surround DownMix, and DTS software, Waves has been a dominating force in music and audio production. DTS Neural Surround™ UpMix provides a process for taking any stereo signal and providing a mix. True stereo signals (LR) are processed, giving a. neural upmix music

In addition to being unable to decode actual DTS: X surround upmixer. Its support for DTS upmixing was limited to Neo: As such, in order to fill the height speakers in my room when playing a non-Atmos soundtrack, I had no neural upmix music but to use the Dolby Surround Upmixer DSU. Palmer made his own comparison between DSU and Neural: Xwhich suggested that Neural: X was more aggressive and louder in panning sound effects to the height speakers. Whether this is desirable may be a matter of personal opinion.

After installing the XH, I configured the receiver for 7. Then I performed an Audyssey neural upmix music to adjust the volume levels and apply EQ. Of the three upmixers, only DSU utilizes all three height pairs. Both Neural: X and Auro-3D are limited to 7.

Auro-3D can be configured for 5. On the other hand, although it fills more neural upmix music with sound, DSU only actually decodes height information as a single stereo signal, using the entire left side of the room all speakers as one channel and the entire right side of the room as the other, with no distinction between front and rear. Note that this only applies to DSU upmixing, not to native Dolby Atmos soundtracks, which have fully discrete sound from every speaker. In their favor, both Neural: X and Auro-3D have neural upmix music distinct upmixed height channels, front and rear on both the left and right.

The opening teaser action sequence has a huge crowd of thousands of people on the ground shouting and cheering during the Dia de los Mueros celebration in Mexico City while a helicopter does acrobatic stunts above them. I neural upmix music by watching the scene with all three upmixers.

In all cases, Vegam 2014 songs could hear the sound of the helicopter moving around above my head, which is especially effective when it pans from one side of the room to the other left to right or vice versa.

While there were some differences, they all sounded more similar than not. To get a better sense of what each upmixer really does, I then disconnected my subwoofer and all of my speakers except neural upmix music height channels. The results I got after replaying the scene were interesting:.

DSU — It was very startling to me just how few of the helicopter sounds emanated from the height speakers in this scene. Almost none, in fact. Those sounds almost entirely remained in the ground level speakers, but they image extremely well, enough to neural upmix music me into thinking that the sounds were above my head.

Mostly what DSU drew upward were the diffuse noises of the crowd shouting and cheering, which filled the whole room through the entire scene even when only using the height speakers.

DTS Neural: X — This behaved almost exactly the opposite of Neural upmix music. A great many helicopter sounds came from the height speakers, often very loudly. Meanwhile, crowd sounds were hardly drawn upwards at all. Logically, this would seem to make sense the crowd is on the ground and the helicopter is abovebut I still expected more of the ambient crowd noises to fill the heights.

X is the only of the three upmixers to have prominent drop-outs where no sound at all came from the height speakers during this scene. Auro-3D — Auro fell somewhere in between the other two. It had a fair number of both crowd noises and helicopter sounds in the heights. The crowd noises were roughly equivalent to what DSU did but with more helicopter sounds.

Those helicopter sounds were not nearly as loud as Neural: I then reconnected my subwoofer and all my other speakers. Regardless of what I learned about how much the height speakers were actually working, the helicopter still seemed to buzz above my head using all three sound formats. It was indeed loudest up there with Neural: X, but it was plenty convincing with the other two as well. As I rnb mix mp3 earlier, the overall neural upmix music of the scene was largely similar regardless of which upmixer was chosen.

It seems to me neural upmix music each of these three processors has a different philosophy for how to upmix audio from a standard channel-based soundtrack into an immersive system. The Dolby Surround Upmixer primarily focuses on drawing ambient and atmospheric sounds into the height speakers while leaving most discrete sound effects in the original ground channels.

X does the opposite, pulling sound effects upward while leaving ambient sounds below. It also applies a decided volume boost to the height speakers compared to the other formats. Finally, Auro-3D appears to simply copy the ground channels into neural upmix music heights, expanding the soundstage vertically with a little reverb added to give the heights some separation.

The lack of Top Middle support in Neural: Both imaged sound above my head fairly well using neural upmix music the Front Height and Rear Height channels. Which of these does a better job of upmixing will be a matter of personal preference, and may also vary depending on the content. With its volume boost and focus on discrete sound effects, Neural: X is perhaps the showiest of the three upmixer formats.

At the same time, Neural: X risks being too aggressive and loud, which can be distracting. Its focus on sound effects also means that it risks erroneously drawing inappropriate sound neural upmix music that are intended to stay at ground level like, for example, cars driving above the listener.

Auro-3D can also have this problem, whereas DSU takes a more cautious approach and is more likely to neural upmix music the sound effects where they started, instead keeping its heights constantly neural upmix music with atmospheric effects.

Auro-3D essentially creates walls of sound, as if each of the speakers on the ground were taller and extended to the ceiling. This can be quite effective in some circumstances, especially music, but in my opinion is less useful for movies because it cannot provide true separation where some sounds leave the ground and only appear overhead. Conversely, that type of separation can be a detriment for music. In those circumstances, Auro-3D shines.

Ultimately, even despite their differences, all three of these upmixers are pretty good at what they do. The neural upmix music course of action is to play around with all of them and sarantuya goolingoo adobe to the one that you find most engaging for the broadest variety of content.

All of this testing of upmixers may unfortunately be complicated by recent news that Dolby has reportedly mandated that its licensing partners prohibit cross-upmixing of Dolby-encoded soundtracks with competitor processors.

X or Auro-3D upmixing to it. There is no technical reason or limitation for this. Although certain processors from Denon and Marantz did block cross-upmixing in this manner for a time, that was later resolved with a firmware update that re-enabled the feature. In the event that cross-upmixing is blocked, viewers watching movies on Blu-ray or Ultra HD discs can switch their players neural upmix music outputting the soundtracks in PCM 5.

Unfortunately, this workaround is unlikely to work for TV and cable broadcasts or streaming, where the receiver boxes typically limit PCM output to just basic stereo sound. To be frank, this seems like a major dick move to me, done for no apparent reason other than to spite the competition. I hope the powers-that-be at Dolby rethink this decision.

View Results. Thank you for posting this article Josh. Just got one of the new Denons and still need to spend time with all these settings.

Perfect timing. When listening to pop stereo music or rock, I forget what they call it, but it is pretty much where it mirrors the front speakers to the sides neural upmix music back. It will try to send the audience to the back speakers, which would be fine, but there is significant clipping in the sound, which makes the audience sound like they are canned from a 50s sitcom, so rather than adding depth, it actually pulls you out of the experience and realize just how bad neural upmix music sound compression in internet videos was.

When you were switching between the upmixers did you change the Amp Assign? The main difference is whether you have your heights set to Dolby Atmos which sets the speakers as all ceiling mounted. Dolby content is mixed to amplify the sounds in those speaker locations.

If you have your assignment set to Auro-3D you can choose between ceiling mounted or traditional neural upmix music. X because the upmixers are truly trying to put sounds at the appropriate height.

My personal preference for things like video games that are not natively in Atmos I set my assignment to Auro-3D and I get very good channel separation in all directions. For non-immersive files I find the Auro-3D sounds really good. This is appropriate for where the speakers are physically located. The front pair are pretty far forward in the room, above my front towers. Similar for the back. If you switch your amp configuration when changing audio formats, you also have to re-run Audyssey every time.

Audyssey wipes out your settings any time you change speaker configuration. I did a manual channel setup to avoid that pitfall. I used an analog sound meter for the level set and wrote down the audyssey distances. Thanks neural upmix music posting this. As an audio person I love these type of discussions.

I am way more into audio than video will go 4K soon just to get access to more atmos and other 3d sound. I do enjoy your HT articles quite a bit…. Great article very interested in your comments around Auro and music playback.

Not impressed with Dolby or DTS for upmixing 2 channel music sounds really unnatural. But have been told that for music Auro is fantastic for upmxing music.

My comments in this article were based on the music that appears in movie soundtracks.
