I've tested Opus @ 256k with 5.1/7.1 material and it sounds great. I imagine one could go even lower. A native wireless protocol for the codec (which is now a standard) would be a good way to go for saving bandwidth.
Interesting... and it's an open format as well.wikipedia said:Opus stream can support up to 255 audio channels[...]
Opus has very short latency (26.5 ms by default)
I also thought of the solution of offloading the 3D spatialization to a separate box, and then sending the stereo signal wirelessly to the headset. However, because the headset has to send the head tracking telemetry to the encoder first before the audio can be sent back, I suspect the latency this introduces makes it unusable. This is based on an earlier post stating that very low latency between the head tracking and spatialized audio is required for proper effect.If mobius is a smash hit and there is staggering demand, I can see Audeze getting licensing and being able to incorporate consoles in the future. It seems like the most universal approach would involve the addition of a break or box that could decode 7.1 to waves NX. Then bluetooth (if wireless was the goal and worked without hiccup) would have double duty of sending pre-virtualized surround sound to stereo to the headset and head tracking data back to the breakout box (which would need to get virtualizion processing duties.)
This solution could be an optional add n as it would diminish the capabilities of the headset not to also have the NX software built right into the headset as well as processing being switchable to the break out box.
I have no idea whether the current headset could be upgradable via firmware to be used like this.
