Rithvik-bit/-Redz-Bluetooth-Router ? reverse-engineered prompt

Build me a Windows app in Python that lets me send my computer audio to two Bluetooth earbuds at the same time and keep them in sync.

I want a simple dark themed desktop app where I can pick two audio devices, start and stop routing, adjust each side’s volume separately, and add a small delay to either device so the sound lines up and does not echo. It should show a live audio level display while it is running, and feel like a polished little utility I can just launch and use.

Please make it work with normal system audio like music, videos, and games, and keep the setup easy for someone who is not very technical. If you need to look up current docs online for any Windows audio or Python parts, go ahead. I’d also like the project organized so it can be run from source and built into a single Windows executable later.
