Description
mp3tomidi.art is a free browser-based tool that converts MP3 and other audio files into editable MIDI format. It uses AI-powered transcription powered by Spotify's basic pitch neural network to detect pitch, onset, and velocity from audio sources. The conversion runs entirely in the browser using TensorFlow.js, requiring no signup or installation. The tool also provides automatic BPM and key detection for any audio file. It includes chord recognition to automatically detect chord progressions from audio. A stem splitter creates music, vocal, bass, and drum stems with a model backend. Users can also render MIDI files to audio formats including MP3, WAV, FLAC, OGG, M4A, and more. MIDI files can be converted to printable sheet music and MusicXML.
