| Soldering iron to the rescue. Locate the microphone and unsolder it. I haven't seen any microphone integrated in the processor. Yet |

| M2 and newer MacBooks have an IMU on-board, which is just a funny way of spelling microphone. Admittedly a very low quality one; I'm not sure if you could pick up understandable speech at the 1.6kHz sample rate Bosch's IMUs seem to support. |

Are there examples of using IMUs to get audio data you could point to? A quick search didn't reveal anything. | | | |

| Going into full paranoid mode, I wonder if some other sensors / components can be used as a makeshift microphone. For instance, a sufficiently accurate accelerometer can pick up vibrations, right? Maybe even the laser in a CD drive? Anything else? |

They are very low level input and generally need a pre-amp just to get the signal outside the microphone. However conceptually at least they are there and so maybe someone can get it to work. |

| Well it doesn’t need to be visible to work in contrast to camera. Seriously though, no technological and almost no economic barrier preventing embedding a mic into every wireless communication chip. |
