Thwarting law enforcement using OpenAI's Whisper to monitor police radio

I don't really think this is a good idea. This is basically adjusting your volume after somebody has already called the police on you- basically hiding evidence.

Instead of coming up with a technical solution, you should just go talk to your neighbors, and the police, and establish what the legal and expected audio limits (time and amplitude) are. Give the police a demo when they arrive. Demonstrate you believe you are within legal limits. Go listen to what it sounds like at your neighbors. Maybe it's a bit louder than you thought? Perhaps your speakers are attached to wood structures that resonate?

If the police are continually visiting you if you're not breaking the law, there are ways to remedy that, as well. Hiding the evidence is probably not a good long-term idea.
