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. Which is a start. Obviously, there is no commercial implementation available in all browsers. On “already available”: At least DD+ is not (maybe you meant AC-3, for which the situation may be different). Best regards, //Christof From: Sursound <sursound-boun...@music.vt.edu> on behalf of Stefan Schreiber <st...@mail.telepac.pt> Date: Wednesday, 3.

However, if we are talking about some solution to code, transport, decode and render HOA within browsers, Mpeg-H currently just can't help. (Because the browser AND OS support for Mpeg-H 3DA is currently "stuck" at exactly 0%. Programming your own "app" might run into license issues. (You don't have such an issue with AAC or even DD+ codecs; which are "already available" if you would chose to use them.) I suppose the Mpeg-I Immersive Audio (which very probably would include support for Mpeg-H 3DA "classic", in the same sense as HE-AAC is a superset of AAC-LC) might have enormous potential for the computer and gaming industry. (However, application is not exactly "imminent". ) Best regards Stefan > "Please also see > > https://urldefense.com/v3/__https://github.com/ittiam-systems/libmpegh__;!!HOHtwYw!FT8U9L-leOGRdV2eq47b7qV69FDM-7gqiT0R31XGsvIrpu2HfqhY0IEHyQJIS0Baa4N-0Wq5OGT7hGlKWxraU-YS$<https://urldefense.com/v3/__https:/github.com/ittiam-systems/libmpegh__;!!HOHtwYw!FT8U9L-leOGRdV2eq47b7qV69FDM-7gqiT0R31XGsvIrpu2HfqhY0IEHyQJIS0Baa4N-0Wq5OGT7hGlKWxraU-YS$> > > and > > https://urldefense.com/v3/__https://github.com/ittiam-systems/libmpeghe__;!!HOHtwYw!FT8U9L-leOGRdV2eq47b7qV69FDM-7gqiT0R31XGsvIrpu2HfqhY0IEHyQJIS0Baa4N-0Wq5OGT7hGlKW_jNaTZE$<https://urldefense.com/v3/__https:/github.com/ittiam-systems/libmpeghe__;!!HOHtwYw!FT8U9L-leOGRdV2eq47b7qV69FDM-7gqiT0R31XGsvIrpu2HfqhY0IEHyQJIS0Baa4N-0Wq5OGT7hGlKW_jNaTZE$> > > " > > With all due respect: > > I really like Mpeg-H and am following the Mpeg-I development, but > Mpeg 3DA is certainly not an open system. > > Even if there is some open code. > > So how do you currently license Mpeg-H 3DA?
