Ivory vs Klangio

Ivory

Ivory handles the specific job of turning a recorded piano performance into readable, editable notation better than generic audio-to-MIDI converters, with hand separation and a score editor built for musicians rather than engineers. The catch is the free tier's 45-second cap, which is too short to evaluate accuracy on a full piece before paying.

Pros

• +Separates left/right hand parts automatically
• +Editable piano roll and score view instead of a flat export
• +Accepts YouTube links directly, not just uploaded files
• +Exports to MIDI, PDF, and MusicXML

Cons

• −Free plan limited to 45-second clips, too short for a real trial
• −Polyphonic transcription accuracy still needs manual correction on dense passages

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
