What it solves
ChordMini 是一款開源的音樂分析工具，旨在自動化從音訊中提取音樂結構的過程。它解決了手動從歌曲中抄寫和弦、節拍與旋律的困難，為音樂人與學習者提供吉他圖表與鋼琴卷軸等視覺輔助。
How it works
此應用程式結合機器學習模型與外部 API 來分析音訊檔或 YouTube 影片。它使用 Python 後端執行節拍偵測（透過 Madmom 與 Beat-Transformer）與和弦辨識（透過 Chord-CNN-LSTM 與 BTC 變體）。為了提供進階功能，它整合 Google Gemini API 進行羅馬數字分析與歌詞翻譯，並使用 SongFormer 進行歌曲分段。實驗性的旋律轉寫則交由獨立的 Sheet Sage 服務處理。
Who it’s for
此工具適合音樂人、音樂學生與製作人，讓他們能快速取得和弦進行、節拍追蹤與視覺化的演奏指南。
