Does Spotify have a way to see if your computer is recording with your DAC’s stereo mix? And if so, is there a way around it?

I don’t know how they’d know unless they could read your computer’s process list or something like that… And even then, how would they know if a process is recording or just receiving audio?
They could add an imperceptible audio watermark
But how would they detect that watermark being recorded by a complete separate process or hardware output?
Which might be good for detecting if somebody somewhat widely distributed a recorded copy, but not if it was just for personal use. Also, if the capture process creates loss there’s a good chance it might degrade the watermark as well
Not even just the capture process. Re-encoding the track to release it into anything lossy, even at a high bitrate, is going to destroy anything that’s inaudible. It would be like trying to read the microprint on the photocopy of a photocopy of a bank note. It’s not going to happen.
Just lossy compress it slightly. Completely gone.
Record with two devices, compare and strip everything away that they do not have in common
Depends on the watermark tech used, for example Cinavia is resilient to compression.
