Why Turning Audio into MIDI by Hand Takes So Long
You hear a riff you love, but rebuilding it note by note in a piano roll means replaying the same two seconds dozens of times. A converter listens for you and writes the pitches, start times and lengths into a file your DAW understands, so you start from real notes instead of an empty grid.
- Working out a melody by ear can eat an entire session before you write a single new idea.
- Chords are harder still: picking three or four notes out of one sound is slow, even for trained ears.
- A hummed idea on your phone is easy to lose when there is no quick way to convert voice to MIDI.
- Most tools want an account, an upload and a long wait before you see a single note.
- Retyping notes by hand introduces timing slips that you then spend more time fixing.
What You Get With This Free Audio to MIDI Converter
Everything happens on your own device, from the first file you drop in to the finished download.
Polyphonic Note Detection
Chords, bass lines and melodies are detected together, so piano to MIDI and guitar parts come out as full voicings rather than a single thin line.
Private by Design
The model runs inside your browser. Unreleased demos and personal recordings never leave your computer or phone.
Free With No Sign-in
Open the page and start. There is no account, no credit system and no watermark on the file you download.
Controls That Matter
Adjust sensitivity, minimum note length and pitch range, then watch the piano roll redraw before you export anything.
Hear It Before You Download
Play the original recording and the detected notes side by side to check that every note sits where it should.
A .mid File for Any DAW
Export a standard MIDI file that opens in Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, Reaper and notation apps.
How to Convert MP3 to MIDI in Three Steps
The whole MP3 to MIDI file conversion takes a few clicks and nothing to install, whether you turn MP3 into MIDI on a laptop or a phone.
- 1
Add your recording
Drop an MP3, WAV, M4A, FLAC or OGG file onto the upload box, or pick one from your device to convert the MP3 file to MIDI. Short, clean recordings of one instrument or one voice give the most accurate notes.
- 2
Let the AI find the notes
The model listens to the whole clip and marks every pitch, onset and note length. A progress bar shows how far it has got, and nothing is uploaded while it works.
- 3
Preview and download
Check the result on the piano roll, play it back, fine tune the settings if needed and save the .mid file to your device.
Features of the EzTranscriber MP3 to MIDI Converter
Built for musicians who want usable notes, not a page of guesses.
Polyphonic Conversion Powered by Basic Pitch
Under the hood is Basic Pitch, the open source note detection model released by Spotify. It handles several notes at once, holds a note steady through vibrato, and keeps each note on its own key, which is why a strummed chord or a two hand piano passage becomes proper MIDI chords. If you have been looking for Spotify Basic Pitch audio to MIDI without installing Python or a plugin, this is it, running in a browser tab. The AI audio to MIDI step happens on your graphics chip when one is available, so longer clips finish faster on a modern laptop. Think of it as a sound to MIDI converter for any pitched instrument.
Try Basic Pitch OnlineVoice to MIDI: Hum or Sing a Melody
Record a hook on your phone, upload the voice memo and get the melody back as notes. Turning a sung idea into MIDI is the fastest way to move it from your head into a synth, and vocal to MIDI works just as well on a finished stem: convert vocals to MIDI when you want to double the line with an instrument or build a harmony around it. You can turn your voice to MIDI free as often as you like. Sing with a steady volume and leave a short gap between phrases for the cleanest result. Want the words as well as the notes? Run the same file through the lyrics transcriber.
Convert My VoicePiano Roll Preview and Playback
Every detected note appears on a scrollable piano roll with a playhead that follows the recording. Zoom in on a bar, play the notes with the built in synth, switch back to the original and compare the two by ear. Seeing the music to MIDI result before you download saves a round trip to your DAW, and it makes it easy to spot a wrong octave or a stray note before it ends up in your project.
Open the Piano RollFine Tune Sensitivity, Note Length and Pitch Range
Noisy room? Raise the threshold so only confident notes survive. Fast runs? Lower the minimum note length. Bass only? Narrow the pitch range to the low register. Each control redraws the piano roll instantly, so you can shape the audio to MIDI AI output without converting the file again, and you can set the tempo of the exported file so the notes line up with the bar grid in your session.
Fine Tune My NotesAudio to MIDI Example: A Melody on the Piano Roll
An eight second piano clip of a well known nursery melody, converted with the default settings.
The top line is the melody and the lower notes are the left hand bass, both detected from the same recording. Note lengths follow how long each key was held, so the long notes at the end of each phrase come out twice as long as the rest. Piano audio to MIDI is the cleanest case, so it is a good first test: drop your own recording into the tool above to create MIDI from audio of your own playing.
What to Do With Your MIDI File
An online audio to MIDI converter is only step one: once the conversion is done, the notes are yours to reshape in any music software.
Drag the .mid into a DAW and assign any instrument: turn a hummed line into a synth lead, swap a piano loop for strings, or layer a bass under a guitar riff. Quantize the timing, transpose to a new key you found with the BPM and key finder, or open the file in notation software and print it with MIDI to sheet music.
Which Recordings Convert Best to MIDI
How clean the notes come out depends on how clearly each one can be heard. Use this as a quick guide before you convert a song to MIDI.
| Which Recordings Convert Best to MIDI | Result | Tip for cleaner notes |
|---|---|---|
| Solo piano | Excellent | Close mics and little sustain pedal blur give the cleanest MP3 to MIDI piano notes and chords. |
| Singing or humming | Very good | Sing one clear line without backing music for a tidy melody. |
| Acoustic or electric guitar | Good | A dry DI signal works better than a heavily distorted amp. |
| Bass line | Good | Narrow the pitch range to the low register to ignore stray harmonics. |
| Full band mix | Mixed | Isolate the part first, then convert the stem instead of the whole song. |
| Drums | Not suited | The model tracks pitched notes, so drum hits are best programmed by hand. |

Audio to MIDI Converter FAQs
Answers to the questions musicians ask most before their first conversion.
How to convert audio to MIDI online?
Drop your file into the upload box at the top of this page. The tool detects the notes, shows them on a piano roll and lets you download a .mid file. There is nothing to install and no account to create, so the whole process takes about a minute for a short clip.
How do I convert MP3 to MIDI for free?
Upload the MP3 here and turn MP3 to MIDI in one step. This MP3 to MIDI converter online is free with no sign-in, no watermark and no daily quota, because the work happens on your own device instead of a paid server.
Is this the best online MP3 MIDI converter for privacy?
It is one of the few that never uploads your file: a MIDI converter online that works offline once the page has loaded. The model runs inside the browser tab, so your recording stays on your computer or phone from start to finish.
Can I convert WAV to MIDI as well?
Yes. WAV, MP3, M4A, FLAC, OGG and other formats your browser can play all work, so you can use it as a WAV to MIDI converter free of charge. Quality depends on how clean the recording is, not on the file type.
How to extract MIDI from audio of a full song?
It detects several notes at once, so chords and two hand piano parts convert well. A full band mix is harder because instruments overlap; for notes you can actually edit, convert one isolated instrument at a time.
Can I convert my voice to MIDI?
Yes. Singing or humming one clear line converts very well, and you can convert audio to MIDI free as often as you like. The melody becomes notes you can play with any instrument in your DAW.
Does it work as a guitar to MIDI converter?
It does. Record the guitar as dry as you can, convert it, and the notes and chords land on the piano roll ready for any instrument or for tablature.
What is Basic Pitch?
Basic Pitch is an open source note detection model from Spotify that finds pitches, note starts and note lengths. EzTranscriber runs it in the browser so you do not need Python, a command line or a plugin.
How do I get the MIDI into my DAW?
Download the .mid file and drag it onto a track in Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, Reaper or any other DAW, then choose the instrument you want to hear.
Why are some notes missing or extra?
Reverb, background noise and overlapping instruments confuse any detection model. Raise the sensitivity threshold to drop ghost notes, lower the minimum note length to keep fast passages, or narrow the pitch range to the instrument you want.
Can I turn the result into sheet music or tabs?
Yes. Open the file with MIDI to sheet music for notation or use the guitar tab generator for tablature.
Can I create MIDI from a YouTube video?
Save the audio of a video you have the rights to use, then convert the file here.
