Issue created Mar 26, 2021 by Ric@tornado99

AptX Low Latency support (including bidirectional audio for high quality voice)?

AptX LL is becoming more widespread, and as I understand it is not a different codec but just a special configuration of AptX.

Could support for this be added to pipewire? (I understand patches are available for pulseaudio)

I attach avinfo from a device with AptX LL capabilities.

Also, apparently AptX LL allows for bidirectional communication if the voice back channel is enabled - this would allow higher quality than current HFP wideband!
