DTS-HD Master Audio 7.1 from other languages
Maybe this is a secret, but I wonder how people get 7.1 audio in the native language when the source doesn't exist, I thought I could make a demux of dolby atmos 7.1 from the english file in wavs and then make a demux of ac3 in my language in wavs and create with the two tracks that were missing a 7.1, but it is not like that since those two tracks may have foreign audio and not in my language, so my question is if anyone knows or has an idea of what's the trick to transform a 5.1 into 7.1 dts
Thanks. |

It is not a secret, it is a edit hard work and have sense only when the english track have better quality than native language:
Take the english 7.1 wav's and replace all the english dialogs with the equivalents in the native language. Not always is easy and not always the output sound good. The easy way, when both tracks have the same quality, is play the 5.1 in a 7.1 system, the AVR make the upmix automatically.

Then I did the same with the track in Spanish but the track is 5.1, so I got 6 wavs, then in DTS-HD Master Audio I added the tracks in Spanish and the other 2 tracks from the Dolby Atmos, but these tracks have backgrounds dialogs in English, so it's a mystery for my to know how to approach this problem. |

The mystery is the "edit hard work" in Audacity (or other audio editor) replacing english dialogs with equivalent native dialogs in all wavs not only the two extra channels.
Add the two extra english channels, even without backgrounds dialogs in English, is a bad idea because async issues. Let your AVR upmix the 5.1 to 7.1 Or duplicate the surround channels with: SL' = 0.7*SL SR' = 0.7*SR BL' = 0.7*SL BR' = 0.7*SR if you want waste time and space to obtain the same 2D surround. My recomendation is buy an AVR + speakers 5/2.1 Atmos and enjoy the 3D surround instead the usseless 2D 7.1 absolutly equivalent to 2D 5.1

5.1 surround to 7.1 surround is a small gain and unless you know what you're doing you might introduce more problems when you're combining multiple sources. The side and back surround channels in commercial soundtrack are also very similar anyway most of the time.
I second the recommendation by tebasuna to have your AVR upscale 5.1 surround to 7.1 surround. |

I don't have the option to buy a new AVR I have an LG SN11RG that it's a fantastic soundbar with Dolby Atmos DTS:X and yes, I can activate the Neural X on DTS sound and it makes a lovely surround like atmos but only works with DTS sound and not all the movies that I have purchased has DTS so my idea was to convert some movies to 7.1 as they do on some internet sites but I see that it is pretty complicated and there is not much information about it.

No, due to the Dolby AVR mandate of 2018 you can't cross-upmix from different vendors. AKA you can't upmix Dolby AC3 to DTS NX, or DTS to DSU. So to upmix AC3 to NX, you must convert to DTS.
This is why the OP is mentioning about DTS 71 from AC3. |
