Please be aware that much of the software linked to or mentioned on this forum is niche and therefore infrequently downloaded. Lots of anti-virus scanners and so-called malware detectors like to flag infrequently downloaded software as bad until it is either downloaded enough times, or its developer actually bothers with getting each individual release allow listed by every single AV vendor. You can do many people a great favor when encountering such a "problem" example by submitting them to your AV vendor for examination. For almost everything on this forum, it is a false positive.

How do modern upmixing techniques work

Hi all,

In the last few years, more advanced upmixing (from stereo to 9.1 or something similar) technologies have surfaced. In the past, there was Dolby Pro Logic for example, but AFAIK that was fairly limited. It did a matrix decode and a few tricks like delaying the rear channels.

The current crop of upmixing techniques like Dolby Surround (not to be confused with the Dolby Surround from the 1980's) and DTS Neural:X seem to be performing differently. Here is an old news article describing/selling it: https://www.soundandvision.com/content/meet-new-dolby-surround

Apparently, Dolby Surround splits the source materials into frequency bands, which are separately steered. Does anybody have any more information on how this works in detail?
Music: sounds arranged such that they construct feelings.
