Use
Passed a fire truck going the other way and it's making you anxious?
No problem—ssh into the laptop on your desk and just type micpeek to
reassure yourself that the fire alarm is not sounding. The gif at the
top of the page is a guy saying some words and whistling some scales,
whereas this is a fire alarm being tested:
Test it out with your own lovely voice before you use it remotely, so
that you can learn baselines for an empty room or open windows or kids
playing video games. But if you have to, you could validate it remotely
by turning up the volume in alsamixer and playing some music.
Acknowledgements
micpeek is built on the
henrikschnor/pasimple
pulseaudio python bindings.
Animations were recorded using asciinema in Comic Mono, converted to gif with asciinema/agg, and compressed with this ffmpeg filter:
split[s0][s1];[s0]palettegen=max_colors=256[p];[s1][p]paletteuse=dither=none
Stalking risk ecosystem impact
Low, I hope. While this example lowers the barrier to entry for hooking up a laptop mic to arbitrary code, it can't do speech recognition; and there's creepier stuff out there that's easier to install and use.
Please don't prove me wrong about that, but if you did, please let me know. :(
