About Klangio
Klangio is an AI-powered music transcription service that converts audio recordings, MP3/WAV files, and YouTube links into editable music notation. Its core purpose is to automate the slow, manual process of transcribing music, letting musicians generate professional scores, lead sheets, and tabs in seconds rather than hours. Users can record a performance, upload an audio file, or paste a YouTube link, and Klangio's instrument-specific AI models detect melodies, chords, and rhythm, including polyphonic and multi-instrumental passages. It offers a range of products such as Piano2Notes, Guitar2Tabs, Sing2Notes, Drum2Notes, and the Melody Scanner app, plus a Transcription Studio. Results can be reviewed in sheet music, piano roll, or guitar TAB views with an edit mode, then exported as PDF, MusicXML, MIDI, or Guitar Pro, compatible with tools like MuseScore, Sibelius, and major DAWs. It's aimed at musicians, composers, producers, educators, and learners of all levels, across piano, guitar/bass, vocals, drums, and more. Klangio is available on the Web, iOS, and Android, with a freemium model: free demo transcriptions for everyone and a Pro subscription that unlocks full-song transcription, more export formats, and editing.
About Opus
Opus is an educational companion app that turns whatever classical piece you're listening to into a clear, elegant introduction — what to notice, why it matters, and where the music is going. It syncs with Apple Music, Apple Music Classical, and Spotify, or accepts a manually shared track, and uses AI-guided musical context to explain works, movements, and composers at several listening-depth levels. A free Listener tier is available forever, with an Opus Pro tier that unlocks deeper listening levels for those who want to go further.
