Audio to MIDI Converter
Turn melodies, stems, and instrumental ideas into editable MIDI using Spotify Basic Pitch directly in the browser.
Automatic transcription
Upload a file and the page estimates the tempo grid for you before building the MIDI draft.
Browser-first workflow
The instant conversion path runs client-side, so you can audition ideas without waiting on a backend job.
Editor-ready output
The generated draft opens directly in our MIDI editor for cleanup, timing fixes, and arrangement work.
From audio idea to editable MIDI
A cleaner visual story for what the tool does before you ever hit upload.
Upload a phrase
Start with a sung melody, piano line, stem, or short instrumental idea.
Generate note data
The converter analyzes the audio, estimates the tempo grid, and builds a MIDI draft.
Refine the performance
Open the result in the MIDI editor to clean timing, fix pitches, and shape the final arrangement.
Audio to MIDI for real music workflows
This is not just a file converter. It is a faster path from a performance idea to something you can edit, rearrange, and export in your DAW.
Producers and beatmakers
Pull melodic ideas out of demos, stems, and voice memos, then move fast into a piano-roll workflow.
Composers and songwriters
Capture a sung melody, rough piano phrase, or instrumental line and turn it into editable MIDI notes.
Creators and learners
Study melodies, rebuild arrangements, or turn audio references into something you can inspect note by note.
How it works
Upload audio, transcribe it locally, then edit or export MIDI.
Upload audio
Choose a WAV, MP3, OGG, FLAC, or any audio file your browser can decode.
Transcribe notes
Spotify Basic Pitch runs locally in the browser to detect notes and create a MIDI draft.
Edit or download
Open the MIDI draft in the editor for cleanup, or download it directly.
What you can do with the generated MIDI
Use the output as a starting point, not just a finished export. The goal is to get you into an editable note workflow quickly.
Start from audio
Drop in a stem, instrumental phrase, solo line, or melodic voice memo.
Generate a draft
We convert the performance into a MIDI sketch with auto-detected timing and note placement.
Polish the result
Open the draft in the MIDI editor, tighten the rhythm, fix wrong notes, and export the final file.
Fast enough for idea capture, structured enough for cleanup
The page is built for a common pattern: capture a melody, get a usable draft, then refine it. You do not need to tune tempo or quantize just to try the tool. Advanced controls are still there when a specific file needs more help.
- Extract a vocal melody from a demo for reharmonization.
- Turn a piano phrase into editable notes for arrangement.
- Convert a separated stem into MIDI before sending it to a DAW.
- Study a melodic idea by inspecting its note placements.
Clean solo lines, stems, and simplified arrangements usually give the best results. Dense full-mix songs may still need some note cleanup in the editor afterward.
Why this Audio to MIDI page is built this way
A little more context for users comparing tools, workflows, and output quality.
Convert audio to MIDI without leaving the browser
This Audio to MIDI converter is built for quick musical iteration. You can upload a melody, stem, or instrumental phrase, let the page transcribe the notes, and move straight into an editable piano-roll workflow. Instead of stopping at a flat export, the generated MIDI draft becomes the starting point for cleanup, reharmonization, arrangement, or DAW handoff.
Best for melodies, stems, and simplified parts
The tool works especially well when the source audio has a clear lead line or a separated part. Vocal hooks, piano motifs, solo instruments, and extracted stems usually translate into more usable MIDI. Full-mix songs can still be converted, but the result often benefits from a quick pass in the MIDI editor to tighten note timing and remove extra detections.
A faster path from idea capture to arrangement
For many users, the hardest part is not exporting MIDI. It is getting from a rough musical idea to a clean editable sketch quickly enough to stay in the creative flow. This page is designed around that moment: upload, transcribe, inspect, refine, and keep moving. The browser-first flow makes it easy to audition ideas before committing to heavier production work.
