Re: [Sursound] Question about UHJ
Hi, Thanks everybody for your well-considered comments. The reason for going for a 2-channel format is compatibility with distribution media formats (CD) - and I suppose it will mostly be listened to without a decoder. The possibility of recovering (2D) B-Format can be very useful, I think (although apparently not 100% possible). My (perhaps idealistic) point, was that if you create as B-format ... then you can export as UHJ, as Blumlein stereo, as ..., ..., ... (and you have B-format in archive, _if_ you ever get the chanve to listen to / play that). But I accept that may be more than you want to do ...

There not streaming at the moment so I cant test it - I would guess that either the browser automatically routes the 4 channels to 1,2,3,4 on the soundcard or there is some way of telling it which outputs to route the 4 channels to. I have an RME too , As long as the RME is set as the default soundcard should be fine.

Surely it would be better to say that the encoding to UHJ is where the loss takes place, and the extraction of speaker feeds or B-format reflects that. This would emphasise the limitation of using two-channel UHJ as an archive format.

Re: [Sursound] Question about UHJ
I could be possible, b-format being the surround essence worldwide would be nice ;). You could select any delivery format on demand, instantly... ex: The binaural option has a great potential for streaming (on headphones). It could spread ambisonics (surround) worldwide, since not too much people has a 5.1 or 7.1 system installed. (in the right way) We´re working on documentary series based on a/b-format.

Setting the speaker layout via Control Panel seems not to make any difference, so I have to assume they are sending a generic 5-channel stream, not a specific WAVE_EX layout.
