The best audio-to-MIDI converter depends on the job in front of you. For a free, quick MIDI, reach for Spotify Basic Pitch. For surgical, note-by-note control, Melodyne is the strongest. For in-session work, your DAW already has it built in. And for the most accurate transcription of a real recording, with readable notation alongside the MIDI, Songscription leads, because its models are trained specifically on recorded music rather than adapted from a general-purpose tool. These tools all listen to a recording and write out the notes, but they do not all finish at the same place or read the notes equally well, and picking by that saves you a lot of wasted time. Here is the field in 2026, what each tool is for, and how to choose.
Fair warning before we start: we make Songscription, so we have a stake in this roundup, including putting it first for accuracy below. We have kept the rest as honest as we can, including the cases where another tool is the better pick for what you need, because you will reach your own conclusions from testing anyway and the useful thing we can offer is a clear read on what each tool is for.
What audio to MIDI does (and does not do)
Audio to MIDI takes recorded notes and turns them into editable MIDI: pitches, timing, and how hard each note was hit, in a form a DAW or notation program can read. Once it is MIDI, you can move a note, change the instrument, or shift the key, none of which you can do to a finished audio recording. The catch is that the output is usually raw. It needs cleanup, a wrong octave to fix, timing to quantize, a stray note to delete, before it is tidy. And it is not the same thing as sheet music. MIDI is note data, not an engraved score; turning it into something a person reads is a further step. If the term itself is fuzzy, what MIDI is lays out the basics, and how to convert audio to MIDI walks the full workflow.
The best audio-to-MIDI converters in 2026
Each of these is good at something specific. The honest one-liner per tool, with its niche, price model, and what it actually outputs:
- Spotify Basic Pitch. Free and open-source, with a browser demo and pip and npm libraries. Polyphonic, instrument-agnostic, lightweight, and it even detects pitch bends. Output is a MIDI file only, so it is the go-to for a fast, no-cost MIDI you will clean up yourself.
- AnthemScore. Converts audio to printable sheet music and MIDI, with strong polyphony, and runs on Windows, Mac, and Linux. One-time purchase from around $20 and up, with a 30-day trial (check current pricing). Output is both notation and MIDI, so it is one of the few that produces a readable score.
- Klangio. An online suite including Piano2Notes and Guitar2Tabs that exports MIDI, MusicXML, PDF sheet music, and Guitar Pro. Free short demo, with a subscription that uses a monthly tickets model (check current pricing). Output spans MIDI through to readable notation.
- Melodyne. A professional pitch and time editor with a Save as MIDI feature and surgical, note-by-note control. Polyphonic editing needs the Editor tier, which lists around $399 on a perpetual license; the entry-level Essential tier is around $99 but is monophonic only (check current pricing). Output is MIDI exported from a deep audio editor, best when precision matters most.
- Ableton Live 12. Includes built-in Convert Harmony, Melody, and Drums to MIDI, so the conversion happens right inside your session with no extra tool. Included with Live (check current pricing). Output is MIDI clips in your project.
- Logic Pro. Can create MIDI from Flex Pitch data, which is monophonic only, so it handles single lines rather than chords. Included with Logic (check current pricing). Output is MIDI from a single melodic part, in-session.
- Songscription. AI that turns a recording into readable sheet music plus MIDI, MusicXML, and guitar tabs in one pass, in the browser. Its models are trained on real recorded performances, so on an actual recording it is the most accurate of these tools at the transcription itself, the notes, the rhythm, and the split between the hands. Free tier covers unlimited 30-second transcriptions, with paid plans for longer files and all export formats (check current pricing). Output is a readable score and the note data together, so a person can read it and a DAW can use it.
How to choose
Match the tool to what you are actually trying to end up with.
- The most accurate transcription of a recording: Songscription, whose models are trained on real recorded music, which tells most on dense, real-world audio rather than clean test tones.
- A free, quick MIDI: Basic Pitch. Nothing to pay, runs in the browser, scriptable if you need it.
- Work inside your DAW: Ableton Live 12 or Logic Pro, since the conversion is built in and never leaves your session.
- Surgical, note-by-note control: Melodyne, for the deepest editing of pitch and timing before you export MIDI.
- Readable notation, not just note data: Songscription, AnthemScore, or Klangio, all of which produce a score you can read rather than raw MIDI.
If your decision really comes down to free-MIDI versus readable-notation, that exact trade-off gets its own head-to-head in Songscription vs Basic Pitch.
From MIDI to sheet music
A reminder worth repeating: MIDI is not notation. If a converter only gives you MIDI and you want a score, you still have to open that MIDI in notation software, which has to quantize the timing to clean rhythmic values and lay the notes out on staves before it reads well. That conversion is real work, and we walk through it in MIDI to sheet music. The alternative is to skip the round trip: tools that produce notation directly from the recording, like Songscription, fold the quantization and layout into one pass, so you go from audio to a readable score without the separate MIDI cleanup. Which route is right depends on whether you want the MIDI for production work or the notation for reading and playing, and for many people the answer is both at once.
Frequently Asked Questions
What is the best audio to MIDI converter?
There is no single best one; it depends on the job. For the most accurate transcription of a real recording, Songscription leads, since its models are trained on recorded music. For a free, quick MIDI, Spotify Basic Pitch is the standard pick. For surgical, note-by-note control, Melodyne is the strongest. For in-session work, your DAW's built-in conversion (Ableton Live 12 or Logic Pro) is the least friction. And if you want readable notation alongside the MIDI, Songscription, AnthemScore, or Klangio produce a score, not just note data.
Is there a free audio to MIDI converter?
Yes. Spotify Basic Pitch is free and open-source, with a browser demo and pip and npm libraries, and it is the most common free choice. Several other tools have free tiers or trials: AnthemScore offers a 30-day trial, and Klangio has a free short demo. If you want readable notation rather than raw MIDI for free, Songscription offers unlimited 30-second transcriptions on its free tier.
Can you convert audio to MIDI and then to sheet music?
Yes, but it is two steps if your converter only outputs MIDI. You first get MIDI from the audio, then open that MIDI in notation software, which has to quantize the timing to clean rhythmic values and lay it out on staves before it reads well. Some tools collapse this into one pass: Songscription, AnthemScore, and Klangio produce readable notation directly from the recording, so you skip the separate MIDI-to-notation cleanup.
How accurate is audio to MIDI?
Accuracy depends mostly on the source. A clean solo line, one instrument with little reverb, transcribes far better than a dense mix where instruments overlap and mask each other. The tool matters too: a model trained specifically on recorded music, like Songscription, reads a real recording more accurately than a lightweight general converter, a gap you notice most on dense audio. Even then, the raw MIDI output usually needs some cleanup: a wrong octave, a clipped note, timing that wants rounding. Feeding the tool the best recording you have is the single biggest thing you control.
