I didn't mention this in the article, but this isn't the first time my family has been driven almost spare by a mysterious, hard-to-track beep.

Our dog goes outside and hides in the lavender bush if a smoke alarm starts making a "I need a battery" noise.

So I went into this project with the attitude that I would like to solve this class of problem forever.

This is very humanizing. I like that.

Nicely done!

> Claude doesn’t have native audio input (yet), but it can run JavaScript and Python code that can analyze audio captured by a microphone.

LLMs can also do that with non-mic audio, btw. I had GLM (or was it qwen?) answer the question of "Why does the spotify version of the Metal Gear Rising" soundtrack sound so bad" - to great results.

Compared with the CD rips on archive.org, the noise floor was 27dB (!!!) higher, and, the whole thing was 10dB more compressed.

I cannot vouch for these specific numbers, but subtracting the good version from the bad one gave me a horrible delta wav file with lots to listen to, so there was definitely a _lot_ of difference.

It got the job done is what I want to say.

The fun part about apartment living is the weird noise can be coming from a neighboring apartment you do not have access to or control to fix.

Pff that sound is horrible, and sorta hard to locate (because of the pitch?). Anyway. None of my neighbours seem to care and in summer I used to hear an orchestra of beeps every 5 seconds. It was maddening, I was contemplating of buying 1000 batteries, print a manual and shoving it in peoples mailboxes, although somehow I think it wouldnt have made a difference. I moved out eventually (not because of the beeps)

Next step isto make an iphone app and robotic arm that throws it and catches it and uses the spinning motion of the phone to triangulate.

Then its solved.
