Switching to Peer to Peer for 1:1 or small group chats would be nice.
Low latency requirements being part of the BT spec would also be nice[1].
OS's fixing their drivers and entire end to end audio stack, that'd also be nice. Get that end to end latency locally to less than the e2e latency of the network packets!
[1] Qualcomm has a low latency version of apt-x which is actually low latency, and Apple does fine with Airpods connected to Mac hardware.
- closeparen 6y agoAirPods Pro connected to Mac hardware still run 144ms. That’s an eternity in live audio world, latency for a genuinely “pro” digital wireless microphone system is closer to 1.4ms.
- com2kid 6y agoHoly cow, I misremembered. That is... so bad. How? Did they let the same people who designed Bluetooth LE's ANCS[1] go hog wild with the desktop stack? Edit: Also I wish that site tested latency for phone calls, since that is often a different protocol. [1] ANCS is, or at least last time I looked at it, a protocol designed by people who had obviously NEVER worked in the embedded or low power space. No limit on message size and no headers indicating the size of the incoming payload are two giant tells.
