Open source chord & beat detection application

Hi everyone,

I recently built ChordMini, an open-source tool that uses deep learning models and LLM to analyze songs and provide:

Chord recognition with 301 chord labels ( 12 keys x 25 types + N)
Guitar chord diagrams (currently no inversion labels)
Beat tracking and synchronized chord progression visualization (with metronome)
Lyrics integration (lrc & model transcription with music.ai api)
LLM used for further abstract analysis (key/tonal modulation correction, song analysis, and structural segmentation through color coded in the beat chord grid).

The webpage is at: ChordMini
The repo is at Github if you are interested.

Feedback, questions, suggestions are very welcome and any contribution is appreciated!

This is pretty impressive, familiar space to me! Congrats on the release! 🎉🎉

Been a music producer myself and built an audio player, radio, and music portfolio as well! 🎵
