You are right on EDGE and Safari on *PC platforms*. Firefox, Chrome, … are a different story. And there is more differences depending on which platform the browser is running (Windows, Android, iOS, MacOS, …). What I wanted to say is that you would need to be more specific for a statement on browser support (is always a combination of browser, OS, maybe even HW).
Nevertheless, I of course agree MPEG-H support on Browser/OS is not “very widespread”. However, it also offers features/compression which are much more advanced than what currently deployed codecs can do. Ok, I see, thanks for clarifying. The statement below refers to DD (not DD+). //Christof From: Sursound <sursound-boun...@music.vt.edu> on behalf of Stefan Schreiber <st...@mail.telepac.pt> Date: Saturday, 6. May 2023 at 00:41 To: Surround Sound discussion group <sursound@music.vt.edu> Subject: Re: [Sursound] [Proposal] for HOA web-streaming-format Short answer: EAC-3 (DD+) is natively supported by Edge and all Safari browsers. I really was refering to this one... AC-3 patents should have expired by now, but of course this codec is a bit old. (And won’t support even 7.1, by the way. The highest channel count would be 6.1, and the B channel would be matrixed into 5.1. If my memory is correctly working. But probably yes... ;-) Thanks, Stefan ----- Mensagem de Fersch, Christof <christof.fer...@dolby.com> --------- Data: Fri, 5 May 2023 16:56:38 +0000 De: "Fersch, Christof" <christof.fer...@dolby.com> Assunto: Re: [Sursound] [Proposal] for HOA web-streaming-format Para: Surround Sound discussion group <sursound@music.vt.edu> > Hi Stefan, > > > > I you are interested in commercially using MPEG-H audio, you can > easily license from VIA: > > https://www.via-la.com/licensing/mpeg-h/ > > > > That is the easiest possible way and similar for the AAC-family. > > > > On browser-support: There is also a browser plugin under the shared > links.
