    Thanks for the tip OD.

    Intriguing enough to prompt dragging an HDMI-equipped laptop into the Man Cave and muck about behind the Hi-Fi rack. Plug-plug, click-click, and I have 5.1 PCM lighting up on the Anthem – woo-HOO !

    I don’t know if “live” is really live-to-air, but the sound in my room is quite enjoyable (Dvorak 8th Symphony).

    Is there any info on how the recording set up/mic positions ? Seems like stage front/ambience (and coughing) rear… but with unusually nice front-to-back continuity. Doubt Ambisonics has any part in it – and no MONO switch here to check fold down quality (a dead giveaway for Ambi’s).

    BUT WAIT… a pause between movements and coughs let out from the front. Maybe the orchestra has a cold.

    Very interesting, and a shame I cannot find any multi-channel stream recorders (everybody can do stereo). I guess the only way is the hard way. Maybe you could use JACK ( http://jackaudio.org/ ) plus your MCH DAW ?

    OK… Back to The Show !

      It’s certainly not ambisonics, just stage front and ambience, as you say. Other than that there’s very little information. Glad you enjoyed it, i’m guessing tomorrows organ recital will be a good one.

    Hmm… shall try and see if my M-Audio Transit USB DAC can pass this signal to my amp tonight.

    Reading further on the BBC FAQ and blogs the stream is AAC-LC. It’s a shame they’re not broadcasting this on Freeview, many set top boxes (and surround TVs) including my HDR Fox T2 can transcode that to 640kbps DD5.1 and output it over optical, which my amp and many people’s can handle. I suspect this would give the BBC a much wider listening base than they’re going to get limiting themselves to the small number of people with laptops that can output 5.1 over HDMI and people that are prepared to drag their laptop to the lounge and connect it to their home cinema system.

    I wonder, is there any way to capture these and convert them to the format of your choice? (whether that is DVD-A or multi channel FLAC or whatever).

      I’ve been trying but have been rapidly getting nowhere

    It is interesting to note these trials are true Quadraphonic, the FAQ points out the Centre channel will be silent because 4.0 works better for classical music. At least they’ve got something right.

    Sigh, why does it always have to be live streaming and browser based? My broadband may not be fast enough to support this and certainly isn’t stable enough at the moment. And my laptop is not connected to my surround system and I have no method of doing so since my amp has no HDMI in and for that matter my laptop can only output stereo over HDMI. I’d far rather download this as multi channel FLACs and then play them later (my Oppo 95 blu ray player will stream multi channel FLAC from a fileserver). Or if this were on iPlayer I could stream this as DD or DTS using my SqueezeBox to my amp over coax.
