Re: [Sursound] [Proposal] for HOA web-streaming-format
Right on the original question and I don’t want to argue either. Just had a small investigation recently and learned myself it is not an easy to answer question. For instance, on mobile platforms, e.g., iOS, the underlying framework is the same for all browsers and there for codec support is (more or less) independent on the browser. On PC-platforms, Firefox and Chromium-based seems to have a policy not to access OS-functionality for media codecs (with exception for some video codecs). In summary: it is a mess and very dependent on many factors. Very widely supported is the AAC-family, including LC, HE-AACv1 and v2 (hopefully soon xHE-AAC also). //Christof From: Sursound on behalf of Stefan Schreiber Date: Tuesday, 9.

Hello Hector! These results make a lot of sense, and are what I would expect: Android does not support Dolby codecs.
