Clear Melody
Best for singing, humming, a bass line, a single-note guitar riff, or a simple piano melody.
Clear, single-note recordings are the easiest to convert. Start here when you want a MIDI draft you can edit.

Audio to MIDI
Converter Online
Turn a clear recording, melody, or separated stem into an editable MIDI draft. Upload MP3, WAV, M4A, or FLAC, review the notes, and take the .mid file into your DAW. Start free with no credit card required.
Step 1
What does your audio contain?
Choose the option that best matches the audio you want to convert.
Choose an audio file
Upload one clear recording to create an editable MIDI draft.
MP3, WAV, M4A, FLAC, AAC, and OGG. Support depends on your browser.
Choose Your Source
What Audio Gives You the Best MIDI Result?
Clear sources produce cleaner MIDI. A solo melody, an isolated instrument, and a full mix need different levels of cleanup. Use the guide below to choose the best source for your audio.
Instrument or Stem
Best for an isolated vocal, guitar, piano, bass, or melody stem.
Use an isolated part from a song. With fewer sounds competing, it is easier to detect notes and timing.
Recommended for songsFull Mix (More Editing)
Best for a short song section with several instruments, when a stem is not available.
Overlapping instruments, drums, and effects can create extra or missing notes. Split the song first when you can.
Use only when neededNeed notes from one part of a song? Split the song into stems first, then convert the isolated part.
Before You Export
Review the MIDI Notes Before You Download
When conversion finishes, open the real MIDI preview in the tool above. Check the detected notes and timing, then download one instrument or all available MIDI files.
Preview Detected Notes
The piano roll is created from your converted .mid file. It does not show example or estimated notes.
Download Each Instrument
When the provider detects several pitched instruments, each available MIDI file appears as a separate download.
Continue in Your DAW
Import the standard .mid file into your DAW to change instruments, remove extra notes, and adjust timing.
Clean Up Your MIDI
Clean Up Your MIDI Draft Before You Export
Audio to MIDI gives you a starting point, not a finished part. Check the notes, timing, and note lengths. Then fix the few errors that matter in your DAW or MIDI editor.
Quantize Timing
Align notes to the beat grid. Use a light setting to keep the performance natural.
Fix Pitch and Octaves
Move notes that are too high, too low, or in the wrong octave.
Adjust Note Length
Trim notes that overlap. Extend notes that end too early.
Remove Extra Notes
Delete false notes caused by noise, reverb, or overlapping sounds.
How It Works
How to Convert Audio to MIDI in Four Simple Steps
Turn a clear recording or stem into an editable draft, then keep shaping it in the tools you already use.
Choose a Clear Audio Source
Upload a melody, instrument recording, or separated stem. Clear MP3 and WAV files give the converter a better signal.
Select the Conversion Mode
Choose a single melody, isolated instrument, or fuller mix so the MIDI draft matches your source.
Review the MIDI Notes
Check the piano roll, BPM, key, and timing. Edit busy sections before you export.
Download or Keep Creating
Export a standard .mid file for your DAW, or keep refining the musical idea in MakeBPM.
Formats and Output
Convert MP3, WAV, and Other Audio Files to MIDI
Upload the clearest file you have. WAV and FLAC preserve more detail, but a clean high-bitrate MP3 can work just as well. Recording quality matters more than the file format.
MP3 to MIDI
Upload a clear MP3 recording, demo, sample, or audio export. A high-bitrate MP3 can produce a useful MIDI draft.
WAV to MIDI
Use a clean WAV file when you have one. It is a good choice for DAW bounces, voice recordings, and instrument takes.
M4A, FLAC, AAC, and OGG
These common formats can work in supported browsers. If a file will not open, export it as WAV or MP3 first.
Best Audio Sources
Clear vocals, simple piano melodies, single-note guitar riffs, bass lines, and separated stems usually need less cleanup.
Standard MIDI Output
After conversion, export a .mid file with editable notes and timing. Open it in a MIDI-ready DAW to choose instruments, transpose the part, or adjust the rhythm.
Accuracy and Limits
What Helps You Get a Cleaner Audio to MIDI Result?
Audio to MIDI works best with a clear, isolated part. A full mix has more sounds competing at once, so it usually needs more cleanup.
Works Best
- Clear vocal, humming, or whistled melody
- Single-note piano, guitar, or bass line
- Separated vocal, bass, melody, or instrument stem
- Short recording with low background noise
- High-quality WAV, FLAC, or clear MP3
May Need More Cleanup
- Simple chords or several notes at once
- Full songs with several instruments
- Light reverb or delay
- Very fast phrases or tempo changes
- Phone recordings with background noise
Not Ideal for Note-Based MIDI
- Drum loops and unpitched percussion
- Heavy guitar or synth distortion
- Very noisy or clipped recordings
- Dense sound effects or long reverb tails
Use MIDI as an Editable Starting Point
Audio to MIDI is a faster way to start, not a perfect transcription. Check the notes before using the MIDI in a finished track or live set. If you need one part from a song, split that part first.
Better Results
Five Tips for Better Audio to MIDI Results
Prepare a clearer source before conversion. These tips can reduce note cleanup when you convert an MP3, WAV, or separated stem.
Start with the part you need
Need the bass line? Convert an isolated bass part instead of the whole song.
Use the best file you have
Use WAV or FLAC when available. Saving a low-bitrate MP3 as WAV will not bring back lost detail.
Trim to the useful section
Remove long silence and unrelated sections. A short clip is easier to check and clean up.
Use a cleaner source
Noise, heavy distortion, long reverb, and delay can create extra MIDI notes.
Check a short section first
Listen to the source and inspect the piano roll. If the notes look too busy, try a cleaner stem.
Use Cases
Ways to Use Audio to MIDI in Your Workflow
Use audio to MIDI when you have a melody or part in a recording and want editable notes for your DAW.
Capture a Melody While It Is Fresh
Record a clear hummed or sung melody. Convert it to a MIDI draft, then continue in your DAW.
Rework a Piano or Guitar Idea
Turn your own or licensed piano or guitar phrase into editable notes. Change the instrument, transpose it, or adjust the timing.
Start with a Separate Stem
Need one part from a song? Split audio you own or can use, then convert the vocal, bass, or melody stem.
Build an Arrangement Draft
Use editable notes from your own or licensed audio to sketch a new arrangement or remix idea.
Study Notes and Rhythm
View the detected notes and timing in a piano roll. Clean solo recordings are the easiest to study.

Last updated:
What is an audio to MIDI converter?
An audio to MIDI converter detects notes and timing in a recording, then creates editable MIDI data. MIDI stores musical events, not the original sound.
Is Audio to MIDI free?
New users receive 12 free credits with no credit card required. The tool shows the credit cost before conversion and charges credits only after the MIDI files are ready.
What audio formats can I convert to MIDI?
Use common formats such as MP3, WAV, M4A, FLAC, AAC, or OGG. Format support can vary by browser, so use WAV or MP3 if a file will not open.
What audio gives the best MIDI result?
Clear, isolated parts work best. Try a vocal, hummed melody, piano phrase, guitar riff, bass line, or separated stem. Full mixes usually need more cleanup.
Can I convert voice or humming to MIDI?
Yes. A short, clear sung or hummed melody is a good starting point. Keep background noise low and avoid heavy reverb or delay.
Can I convert a full song, chords, or drums to MIDI?
These sources are harder because several sounds overlap. Start with a separate stem when you need one part. Expect to review and edit results from chords, drums, or a full mix.
What if the MIDI has extra or missing notes?
Try a cleaner source or an isolated stem first. Then check the piano roll, remove extra notes, and adjust timing or note length in your DAW.
Can I use the MIDI file in Ableton, Logic, or FL Studio?
Yes. A standard .mid file opens in MIDI-ready DAWs such as Ableton Live, Logic Pro, FL Studio, Cubase, and GarageBand. You can then change instruments, edit notes, or adjust rhythm.
Do I need rights to the audio I upload?
Yes. Only use recordings, stems, samples, and songs that you own or have permission to use. Converting audio to MIDI does not give you rights to the original music.
What happens to my audio file?
Your audio is uploaded to MakeBPM storage and sent to our processing provider to create the MIDI result. See our Privacy Policy for details about data handling and retention.
