We get to pick whether we try to handle this ourselves or let the OS up/downmix too. In practice, I don't think it matters that much. Many 'surround' audio devices/drivers will make something up when fed stereo input. There are even a bunch of "surround sound demo" videos on Youtube...which only supports stereo. What does matter is properly spatializing audio for games. Our feedback from designers is that headphones are very popular with gamers for both performance and social reasons, so what I don't want is support for surround playback on home theatre systems to eclipse headphone gaming. We need to support both use cases well. > Web Audio requires non-interleaved channels. I think we should adopt > that everywhere we can. These sounds fine. The only thing I worried about was float-only support, but I supposed the performance difference on mobile isn't that big a difference. So: no channel mapping metadata, just reuse the speaker set and order from WebAudio, which we hope will converge with the WAVE order and the speaker sets Vorbis and Opus already support. -r _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
