Does the laptop have knowledge of the screen angle, or does its calculations just assume an 'average' angle? Or does it not matter too much (it seems like it would to me)?
Yes, modern MacBooks have a sensor for detecting screen angle

They do, and it's also used for Desk View when you use an iPhone as your laptop's webcam. This undoes the perspective of whatever is in front of your laptop, basically like an overhead projector: https://www.macworld.com/article/1371720/continuity-camera-m...
Pretty cool that speakers are driven in part by software that knows the screen angle. Add in the position of your head and you'll be able to do amazing things with those speakers. Sad that you can't get studio monitors that are integrated enough to do this on the fly (or can you???)
What a great way to describe it!
> the sound stage is eerily wide on the M1 MBP (and presumably the M2 Air), compared to the normal side speakers.
Thank you for giving me the new language to express this! :) ;p x
Probably they're pre-distorting the sound so it's correct only after bouncing off the screen, kind of like how VR distorts the image to account for headset optics undoing that distortion.
I had an M1 Air before the MBP release. The sound was good, but the sound stage is eerily wide on the M1 MBP (and presumably the M2 Air), compared to the normal side speakers.
