Fair is fair

When Klangio is the better choice

  1. 01

    You want an app built around one instrument

    Klangio's per-instrument apps, like Piano2Notes, focus on one instrument at a time. If you only ever transcribe that instrument, the focus may suit you.

  2. 02

    You're starting from a video link

    Klangio accepts video links. We don't take links at all, only files you upload and have the right to use.

  3. 03

    You want a published refund window today

    Klangio lists a 14-day refund window. Ours is still being finalized and will be published before launch.

FAQ

Questions people ask

Klangio offers a free demo. At our October 2026 check, transcriptions previewed the first 20 seconds, Scan2Notes the first 12 measures, and free export was PDF only. Paid plans started at $14.99 a month for Instrument Pro. Klangio's site has the current terms.

Piano2Notes is Klangio's piano transcription app. Audio2MIDI.org covers piano along with voice, guitar and full mixes, plus PDF scanning and MIDI tools, in one workspace. Our free Fast mode lets you hear the whole piece before you decide on HQ.

Yes. Klangio has Scan2Notes, and our Sheet Music Scanner and PDF to MIDI tools read PDF pages or phone photos. Scanning costs 2 credits a page here, and a free account gets a one-page preview each day with playback and the first 8 measures.

On Audio2MIDI.org, MIDI to Sheet Music exports MusicXML and PDF for free. MusicXML from an audio transcription needs credits or a plan. At our check, Klangio's free tier exported PDF only, with MIDI and MusicXML on paid plans.

Not here. One account covers piano, voice, guitar tabs and full mixes; you pick a preset when you convert. Klangio organizes its products by instrument, so piano and guitar transcription live in different apps there.
