Web Spectrogram using your Mic

This made me curious and I went and found https://www.szynalski.com/tone-generator/. (Can strongly recommend ignoring this site's volume control and using your own for the lower frequencies!) Playing around with briefly unmuting my audio output for short bursts, I found I couldn't go past 17kHz too. I did need to judiciously turn the volume up though.

We used something similar in school assemblys years ago, every student was able to hear it, the whole assembly errupted in chaos and none of the teachers were able to figure out what was happening. Good times.

Like short bursts over the PA? That's absolutely hilarious.
