Use tool ↗About Klangio
Klangio does audio-to-notation: record, upload a file or paste a YouTube link and it detects the notes, then exports PDF sheet music, quantised or raw MIDI, MusicXML or Guitar Pro files. It covers piano, guitar, drums, vocals, violin and wind instruments through both a single Transcription Studio and instrument-specific apps such as Piano2Notes, Guitar2Tabs and Drum2Notes, plus Scan2Notes for photographing printed scores. An edit mode with piano-roll and score views lets you fix what the model got wrong before export, and a DAW plugin ships as VST3, AU and standalone. Klangio GmbH is based in Karlsruhe and was founded in 2018 by Sebastian Murgul and Alexander Luengen.

Pros & cons of Klangio
Klangio is the most complete audio-to-notation stack on the market: browser studio, per-instrument apps, a DAW plugin and an API, with exports that open in MuseScore, Sibelius, Finale and Guitar Pro. The edit mode matters, because polyphonic transcription still misses notes and you will be correcting output rather than printing it. Annual billing is less than half the monthly rate, which is a real commitment for a tool you may use in bursts.
Pros
- Exports PDF, MIDI, MusicXML and Guitar Pro, so output lands in real notation software
- Covers piano, guitar, drums, vocals, violin and winds, not just piano
- Editing view with both piano roll and score before you export
- DAW plugin in VST3, AU and standalone alongside the browser app
- A documented API for developers, plus mobile apps
Cons
- Monthly billing at $19.99 costs more than double the annual rate
- Transcription accuracy drops on polyphonic and noisy material, so edits are expected
- The prices live on the plugin page rather than a normal pricing page, which makes comparison awkward
Best for
- Musicians learning songs by ear who want a starting score
- Teachers preparing arrangements from recordings
- Producers pulling MIDI out of an audio reference
Not for
- Anyone expecting publication-ready engraving with no correction
- Dense orchestral or heavily processed mixes
Watch out: The advertised $8.49 is the annual plan divided by twelve; paying month to month is $19.99.
