Magic Chords – Web app for chord recognition and audio transcription (magic-chords.dev)

Magic Chords has launched a free web app for automatic chord recognition and audio transcription, offering musicians a streamlined workflow to analyze songs effortlessly. Users can upload audio files or paste URLs, and the app employs advanced algorithms from Madmom and Essentia for accurate chord detection while also leveraging OpenAI’s Whisper for automatic lyric and melody transcription in over nine languages. The platform allows real-time playback with adjustable speed, facilitates the editing of chords and lyrics, and includes features like audio transposition and key detection, all designed for easy navigation and use. This tool is significant for the AI/ML community as it not only demonstrates the practical application of machine learning techniques in music but also makes complex audio analysis accessible to a broader audience, from amateur musicians to educators. The app supports various formats for export, including MIDI and MusicXML, enhancing its utility for diverse musical needs. With plans for potential premium features and the foundation laid on open-source libraries, Magic Chords could inspire further innovation in audio processing and transcription technologies, making music creation and study more efficient.
