SoundToMIDI converts a WAV recording into editable MIDI notes in your browser. Preview and download Raw MIDI free without signing up; conversion does not upload your audio. Start with one clear instrument or vocal line.
Free Raw MIDI. Optional paid export for edits & scores.

MP3 · WAV · FLAC · M4A · OGG · AAC · MP4 · WebM · up to 100 MB — stays on your device
Best with one voice or instrument. Try a 15–30-second phrase.
File support & processing time
A short clip may take 30 seconds–2 minutes; longer audio can take several minutes or more. Device speed and the first model download affect timing.
MP4/WebM need a browser-readable audio track. If a video will not open, export MP3 or WAV. For files over 100 MB, shorten the recording or extract its audio.
Profiles adjust detection, pitch bends and cleanup. You can fine-tune them in Advanced settings.
Or record a solo voice or instrument · up to 60 seconds.

Refines detected notes; does not improve the transcription model.
Your sheet music draft
Automatic draft. Review notes and rhythm before export.
Score settings & limitations
Bar offset adds leading rests to align a pickup; it must be smaller than one bar. Notes below the split go to the bass staff. Empty staves are omitted. Tempo comes from your MIDI timing controls.
PDF and MusicXML use this score; MIDI keeps your edited timing.
Automatic draft · Fixed tempo · Sixteenth-note grid · Suggested hand split. Review notes and rhythm; tuplets, pedal, fingering and tempo changes are not inferred. Swipe sideways inside the paper on small screens.

Which recordings work best?
An isolated piano, guitar, bass or vocal part is a better starting point than a finished mix. Use a dry take with clear note attacks, trim long silence and select a short phrase before converting the whole recording. If the original MIDI exists, use it instead of transcribing the audio.
WAV preserves the source audio without the lossy compression used by MP3, but it cannot fix noise, clipping or overlapping instruments. Re-saving an MP3 as WAV does not restore lost detail. Keep your original 44.1 or 48 kHz recording; upsampling is not a transcription shortcut.
Solo melody or stem: compare the detected pitches and note lengths with the recording.
Piano chords: check the inner notes as well as the highest and lowest notes.
Full mix or heavy reverb: expect more correction; isolate the part first if you can.
Unpitched drums: this converter does not create kick, snare and hi-hat MIDI lanes.
Choose a profile for your recording
Profiles change note-detection and cleanup settings; they do not separate instruments into stems. Choose the part you want to transcribe, then listen to the result.
General: a balanced starting point when the source does not fit another profile.
Voice: a solo sung or hummed melody, including pitch slides.
Piano & Guitar: shorter attacks and chords, with pitch bends off.
Bass: a low-pitched line, with cleanup that favors the lowest notes.
How do I fix extra or missing notes?
Compare Original audio with Raw MIDI before editing. For many tiny false notes, try increasing Onset confidence or Min note length in Advanced settings. For missing quiet notes, lower Note confidence slightly. Change one setting at a time and reconvert the same passage. Changing Tempo does not improve pitch detection.
Import the free Raw MIDI onto an instrument track in your DAW and keep the WAV beside it. Assign an instrument so you can hear the notes, remove obvious extras, correct wrong octaves and note lengths, then adjust timing. MIDI contains estimated note instructions, not the original voice, instrument sound, lyrics or studio tracks.
You can also preview cleanup and edit notes here. The optional Music Export Pack exports your edited result and notation drafts; it does not run a stronger transcription model. On-page edits do not change the free Raw MIDI file.
A WAV example with two extra notes
This original eight-second synthesized melody contains eight source notes. In our September 28, 2026 browser test, Raw MIDI contained ten notes: all eight source pitches had a matching event, plus two extra high notes. This is a controlled example, not an accuracy score for real songs.
Listen to the source WAV
The test used General settings: onset confidence 0.5, note confidence 0.3, minimum note length 130 ms, 120 BPM and pitch bends off. Open the example in the converter to hear its Raw MIDI preview.
Check the two extra D5 notes against the source D4 notes. Removing those extras is a manual correction you can make in your DAW with the free file.
The saved test result. Matching pitch and start time does not measure note length or expression.
Keep the original recording beside the MIDI so you can compare pitch and timing. If you use Logic, the Logic Pro audio to MIDI guide explains Flex Pitch and how to check the resulting notes. For NewTone and Piano Roll steps, follow the FL Studio audio to MIDI guide.
WAV to MIDI — FAQ
Is WAV to MIDI free, and do I need an account?
Conversion, preview and Raw MIDI downloads are free without an account or a daily conversion count limit. Processing uses your device. On-page editing is free to preview; exporting those edits uses the optional Music Export Pack. Cloud project backup is optional and requires sign-in.
Does the downloaded MIDI have a watermark?
No. The free Raw MIDI contains the detected notes without an added watermark. It is a standard .mid file you can edit in a DAW; it does not contain the sound of the original recording.
How long does conversion take?
There is no fixed completion time. It depends on the selected audio length, your device and the browser; the first run also needs to load the model. Start with a short phrase and follow the progress shown in the tool rather than expecting an instant result.
Which WAV recordings and file sizes are supported?
Choose one browser-decodable WAV file up to the displayed 100 MB limit (104,857,600 bytes). Ordinary 44.1 or 48 kHz recordings are suitable. Isolated piano, guitar, bass and vocal parts are useful inputs. Decoding a long recording still uses device memory even if you select only a short passage.
What do I download, and how do I use it?
The free output is a standard .mid file containing estimated pitches, note starts, durations and velocities, with pitch bends when enabled. Import it onto an instrument track in your DAW, choose a sound and compare it with the WAV. The optional export pack adds Edited MIDI, notation drafts and other practice files; MIDI itself has no audio sample rate or image dimensions.
Can it turn a full song into separate MIDI tracks?
No. This tool does not separate a mixed song into vocal, bass, drum and instrument tracks. Dense mixes, distortion and reverb can produce extra or missing notes. Use an isolated stem or a cleaner recording, and check the transcription by ear before relying on it.
