Hi all,

I have a USB C headset.

I am setting it up, so it’s plugged into my Linux box, so it can listen to music, and make calls, etc from my phone, via bluetooth.

Then I don’t have to keep unplugging my headset and plugging it into my phone.

Also so I can record directly to the Linux machine, that is broadcast from my phone.

But, how can I intercept the Bluetooth audio, and record it?

Thank you.

    Wait, it’s plugged into the computer, and connected to the phone via Bluetooth, and you want to intercept the bluetooth signal to record the audio to your computer…? Am I understanding right? That kinda negates all of the advice I gave. That’s a super convoluted thing to try and do, and well beyond the scope of basic technical advice 😅

    It seems to me like it’d be easier to record the audio via your phone and automatically send it from your computer, rather than intercept the bluetooth signal, but even that would be complicated if you want to do it automatically

      That’s exactly right, that is what I’m trying to do. :-)

      I’ve almost got at working, I have pulse audio recording the signal that’s coming to me, I guess via the Bluetooth speaker function. So the phone is treating the computer as a Bluetooth speaker.

      However when I talk, it does not record anything from the microphone going back to the phone.

      So my headset is a USBC, with mic an headphones (speakers).

      The signal coming from the phone to my ears can be recorded.

      But when I talk and speak back to the phone through my headset microphone, it does not record.

      This is the command I am currently trying, but I will dig deeper:

      pw-record --volume=1.0 -P '{ stream.capture.sink=true }' /home/userName/Temp/Test.ogg

        I’m not sure linux noobs is the best place to find the answers you’re looking for, a more technical forum is more likely to have people interested in finding answers to your situation. Regardless, that’s well beyond me unfortunately, I’m not the most technical user 😅

        Good luck! I hope you get it working!

          Thankyou so much, I guess I was hoping there would be some Grand Lord Master of the Bluetooth Linux Audio Channel Recording legend kind of person living here. :-) Stroking their cat, and meditating at the screen whilst levitating in a yoga pose, dispersing waves of confident knowledge into lemmy.

          Maybe that will be me one day :-)

          One can only hope

            Lol, don’t let your dreams be dreams! I believe in you! And when I need to install pipewire I’ll have someone to ask lmao

            Good luck! I hope you’re able to find your solution ☺️

      Just to put things into even more of a spin, I just tested it with a phone call, and now it records my voice through the microphone, but it doesn’t record the speaker’s voice coming back through the speaker.

      I guess on a phone call it’s switched around?

      This Is Going to Be Challenging :-)

      I want to do it all on the computer because I want to run processing over it via an AI, and I want it done local on my machines so that it is private, and nobody has their voice shared with anybody else.

      It’s a bit of an experiment and I just want to see if I can do it. It will greatly speed up my workflow if I can.
