Description
Klangio is a suite of AI-powered tools that transcribe music into notation. Users can upload an audio file, record directly, or paste a YouTube link, and Klangio's instrument-specific AI models analyze the recording and produce editable notes, chords, melody, and rhythm, replacing the hours of manual work traditional transcription requires.

The suite includes dedicated apps for individual instruments such as Piano2Notes, Guitar2Tabs, Sing2Notes, Drum2Notes, Violin2Notes, and Wind2Notes, plus Klangio Transcription Studio, an all-in-one workspace that transcribes full songs with multiple instruments at once. A Transcription Plugin brings the engine into a DAW with a focus on MIDI output, and additional tools include Scan2Notes for scanning sheet music, Melody Scanner, and Song Search. A developer API and bulk transcription are also available.
Transcriptions can be viewed as sheet music, a piano roll, or guitar tabs, refined in an Edit Mode, and exported as PDF, MIDI (quantized and unquantized), MusicXML, and Guitar Pro, compatible with tools such as MuseScore, Sibelius, Dorico, Finale, and major DAWs. Klangio apps run in the browser with no download, and on iOS and Android.
Every app has a free tier with unlimited 20-second demo transcriptions, and Pro or Ultimate subscriptions unlock full-song transcription, unlimited exports, more formats, and Edit Mode. Klangio is developed by Klangio GmbH in Karlsruhe, Germany.
