    I think my question is more “Does this only work on MacBook Pro” though now I wonder how much the angle the Mac Book is open will matter to the program, or if an external microphone will affect it (or completely throw it off).

    Not trying to tear this down, but more understand the scope needed for this attack to work, or what could break this approach.

      They used an iPhone 13 mini, 17 cm away, to record the keyboard’s audio for their first test. For the second test, they recorded the laptop keys over Zoom, using the MacBook’s built-in microphones, with Zoom’s noise suppression set to its lowest level. In both tests, they were able to achieve higher than 93 percent accuracy, with the phone-recorded audio edging closer to 95-96 percent.

      So it can be listened to by a nearby device or over zoom it seems.
