Klangio

Klangio is an AI-powered music transcription platform designed to convert audio recordings into precise, editable notation. It automatically transforms songs, performances, and YouTube videos into sheet music, MIDI, and MusicXML, enabling users to move seamlessly from sound to structured musical data. The tool’s primary purpose is to streamline the transcription process for musicians, educators, and producers who need accurate notation without manual note-by-note work.

Klangio supports polyphonic transcription, allowing it to handle complex pieces with multiple instruments or dense harmonies. Depending on the app within the Klangio ecosystem, users can extract melodies, chords, and full arrangements, then export them into standard formats for use in notation software or digital audio workstations. The platform offers tempo and key detection, instrument recognition for selected use cases, and bar-aligned outputs to facilitate editing and arrangement. Integration with YouTube links and uploaded audio files makes it suitable for both quick one-off transcriptions and more detailed scoring workflows.
