Penteo Pro 16 Upmix/Downmix Plug-In

[HomerJAU]

More on the Penteo issue: It turns out the specific source rear channel high frequency breakup is in all Penteo 16 versions. I only hear it on certain tracks, not many. Over the weekend I tried 4 different Penteo versions, listening to the rears solo in Audacity. Initially I thought an early version did not have the issue. That conclusion is incorrect (my mistake in listening tests). It’s also not specific to my PC setup as I asked @J. PUPSTER to do same upmix and got same results.

I‘m sending a couple of sample stereo tracks to Penteo to see if they can improve the upmix in a future update.

Looks like some interesting developments going on with Penteo, not sure I'll partake in the extra abilities but some here might?

The fact that they're enumerating a bunch of "x.x.4" 360RA formats implies that they're anticipating people having the ability to decode 360RA to multi-speaker systems with overheads soon.

No 22.2 mixing/remixing

New AVRs are getting MPEG-H 3D/RA360 decoders.

Not sure why they called the new formats Sony RA360. It’s MPEG-H 3D, an international standard being used in new immersive TV broadcasting. The format names are defined in the ITU standard not the clunky names shown in Penteo.

I expect they're just reflexively deferring to the 500-pound gorilla, which wants to train people to call MPEG-H 3D facial tissue "Sony 360RA Kleenex" instead. (Even more brazen than Apple's half-hearted attempt to stamp Atmos with its "Spatial Audio" brand. At least that move pitted one corporate giant against another, sort of. Not clear to me, however, whether MPEG-H 3D is totally open-source, or merely an open-source implementation of a "patent-encumbered" codec.)

Garry, do you have any sense of whether the MPEG-H decoder involves a separate chip, or can it be done with software? Just wondering whether there's any chance in hell of adding MPEG-H 3D to an existing receiver.

There is an obvious market for an outbound MPEG-H 3D decoder (HDMI) but will we ever see one?

The MPEG-H 3D spec is defined in a ITU specification. There are no licensing fees to decode/encode, however if someone creates software or embedded chip to decode its likley they would charge a fee for the likes of Denon and Marantz to use it.

Thanks. Also--as long as I've already diverted this thread: have you managed to get a copy of Fraunhofer's MPEG-H Authoring Suite, and if so, have you been able to use the included MPEG-H VVPlayer to send files to your AVR? (Would that be included under "various sinks"?)

https://www.iis.fraunhofer.de/en/ff/amm/dl/software/mas.html
Highlights of the MPEG-H VVPlayer 1.6.3:

• Playback of MPEG-H Audio media files including support for H.264/AVC and H.256/HEVC video. Video decoding capability relies on OS-level decoder support
• Output of decoded audio to various sinks including binaural playback on headphones

No, I haven’t tried.

I’d want an AVR/External decoder solution. When I listen to music I want to just play anything ad-hoc, not switch between playing systems. Point and play, all my music is on a shared NAS server and I can play everthing/anything from either of my two surround systems. Even switching discs is too painful to endure, my Oppo and a Sony BD player are in a cupboard, havent been used for years.

Some of us without overly complicated receivers, prefer decoded PCM to keep it simple.

Decoding to PCM is often way more complex than using an AVR though.

It's $250 to upgrade Penteo Pro 16 to Penteo Pro 16 Plus. It's not worth it for me, because it's mostly just adding the 360RA. For an amateur upmixer, I would say that the $250 upgrade cost would be better spent going towards the cost of DeMUX Pro, or a similar type program, unless you really want that Sony 360RA file output

That isn't what I meant. Needless bells and whistles on receivers and having to upgrade for every new format just isn't for me. I like to keep it simple. I keep all my files PCM, already decoded. I realize it isn't the norm, but it works for me. We can all get along!

Got this Penteo sale in my email recently; good through 12/01
