Hey Product Hunt! 👋 I'm the maker behind LUA Music Studio. This project started with a simple problem. I created a song using AI and wanted to play it on my guitar. But I couldn't find an easy way to get the chords I needed. The tools were scattered across different apps, and many "free" services came with song limits, credits, or paid subscriptions. So I decided to build my own. 🎸 **What LUA Music Studio can do:** - Detect chords, key, and BPM from YouTube links or audio files - Generate sheet music - Separate vocals and backing tracks - Loop sections and adjust playback speed for practice And here's the part I'm most proud of: **It's completely free.** No ads. No credits. No subscriptions. No usage limits. It's currently available for Windows, with macOS support in development. I originally built this because I needed it myself. Now I'm sharing it with anyone who loves making, learning, or playing music. I'd love to hear your feedback, especially about chord accuracy and features you'd like to see next. Thanks for checking it out! 🎵
