Music recognition tool

A song recognition app that runs entirely in your browser.

🎵 Song Recognition
Identify songs by dropping audio/video files or recording with your built-in microphone. Before sending, it automatically performs "10-second trimming → mono conversion → 16kHz downsampling → WAV conversion" to minimize data transfer to ACRCloud. Recognition results are displayed with confidence scores, showing up to 5 candidates that you can switch between.

📚 Information Retrieval
After recognition, detailed information is retrieved in parallel from MusicBrainz, iTunes, Wikipedia, Spotify, and YouTube. Artist Wikipedia summaries, album art (up to 1200px), ISRC/UPC badges, composer/lyricist information, genre tags—few tools gather this much information in a single recognition.

🎬 Playback
YouTube MVs are embedded for playback (currently in development and probably won't work. We're doing our best!).
Spotify embedded player and iTunes 30-second previews can also be played on the same page.

🗂 History & Cloud Sync
Recognition history is saved locally in IndexedDB. Cloud sync to Cloudflare D1 is also supported—simply enter a UUID on another device to restore your history. Differential sync occurs automatically every 5 minutes, with communication skipped on background tabs. You can also check global recognition rankings (cumulative and monthly) and your top 10 recognition counts.

⭐ Other Features
Favorites registration and filtering, filtering by date range and confidence level, recognition statistics dashboard (3 types of graphs with custom Canvas rendering), share card image generation and download, adding to Spotify playlist "Music Recognition Tool," JSON/CSV export, offline launch support via Service Worker. Dark mode and keyboard shortcuts fully equipped.
