robotaitai/resoscan ? reverse-engineered prompt

Build me a simple web app that helps people measure the resonance in a room using their microphone and speakers.

I want it to play a sine sweep, record the sound back through the mic, and then show the results in a clear way so I can see which frequencies the room is boosting or cutting. It should let me pick the input mic and output speakers, choose how long the sweep runs, and warn me if the audio is clipping or too loud.

Please include a live level meter, a frequency response view, an impulse response view, and a list of the strongest resonant peaks with their frequencies. I’d also like a place to upload a mic calibration file so the readings are more accurate. Make it look good in both light and dark mode, and keep it easy to use in a browser on a laptop or desktop. If you need current browser or audio API details, look them up online.
