About
Klangio is a comprehensive AI music transcription platform that automatically converts audio into professional musical notation. Whether working with an MP3 file, a live recording, or a YouTube link, Klangio's AI engine detects melody, chords, and rhythm to generate accurate sheet music, guitar TABs, MIDI, and MusicXML in seconds. The platform provides a suite of instrument-specific transcription apps — Piano2Notes, Guitar2Tabs, Drum2Notes, Sing2Notes, Violin2Notes, and Wind2Notes — each optimized with tailored AI models for precise results. For complex multi-instrument projects, the Transcription Studio and its DAW Plugin handle full arrangements and integrate seamlessly with popular Digital Audio Workstations. Additional tools include Scan2Notes for digitizing printed sheet music, Melody Scanner for generating piano arrangements from full songs, and a Song Search feature for chord analysis. A Bulk Transcription API is also available for developers and businesses requiring large-scale or automated notation workflows. Ideal for music teachers, self-taught musicians, composers, bands, and professional transcribers, Klangio reduces hours of manual work to seconds. Exported files are compatible with leading notation software and DAWs via Sheet Music PDF, Guitar Pro, MIDI, and MusicXML formats. New users can transcribe the first 20 seconds for free, with a 14-day money-back guarantee on paid plans.
