My wife is streaming a fitness class and attempting to use Bluetooth headphones to listen to music and also feed the music into the stream using Loopback. This is working well but the stream gets 0 latency on the audio and her Bluetooth headphones have noticeable latency so she ends up doing things off beat.
Using Bluetooth explorer, I’ve tried forcing both her MacBook (2015) and my MacBook (2019) to use AptX with 0.0 latency but there is still latency. I also tried using a Bluetooth receiver that supports AptX and plugging that into the headphone jack on her MacBook but still had out of sync audio to the headphones and the MacBook speakers.
Now I’m wondering if I can add a delay or latency just to the MacBooks speakers, not to the Bluetooth headphones. Is there a way to do this just for the one audio source?
(I’m also open to other solution to this situation in general)
