Re: [Sursound] FLAC and max number of channels

Hi Panos, The Ogg FLAC  documentation does not mention that more than 8 channels can be encoded. I tried using ffmpeg; this is working for 8 channels: ffmpeg -f lavfi -i "anoisesrc=d=1:c=pink:a=0.5" -c:a flac -f ogg -ac 8 -y noise-8c.ogg But this is not working for 16 channels: ffmpeg -f

To my knowledge browsers don't support more than 8 channels, and configuring them for outputting more than 2 channels is probably a challenge for most users. One solution is to use MPEG-DASH and reassemble parts and decode them. But as with anything "Hi-Fi", the reproduction system is key, so u

Re: [Sursound] cross-talk cancellation used in binaural sound reproduction

It is similar: The Carver C-9 is cancelling one occurence of cross-talk by mixing in to each channel a delayed inverted copy of the other channel, while the RACE algorithm cancels the following cross-talk occurences recursively because the mixed delayed inverted signals must also be cancelled..
