01 — Your recording, as notes
Free online audio to MIDI converter
Turn a voice note, guitar riff or piano recording into notes you can arrange. Loudness.ai offers free audio to MIDI with playback, editing and .mid download. This online MIDI converter captures note pitches, timing, lengths and velocities. AI audio to MIDI makes automatic music transcription a starting point for your next song.
MP3 to MIDI, WAV to MIDI and other formats
Use the MP3 to MIDI converter for saved songs and samples, or the WAV to MIDI converter for original instrument takes. M4A to MIDI suits phone recordings; FLAC to MIDI works with lossless audio. AAC to MIDI, OGG to MIDI, Opus to MIDI and WebM to MIDI are also supported for recordings in those audio formats.
Use your clearest recording. Changing an MP3 into WAV first will not recover lost detail. For a long song, trim the passage you want to reuse before uploading.
02 — How it works
How to convert audio to MIDI online
Upload your recording
Choose a supported audio file up to 50 MB and five minutes long. Keep the tab open during conversion.

Play the piano preview, compare it with the original and edit MIDI notes in the piano roll. Add missing notes or remove unwanted ones.
Download MIDI
Choose the export tempo, save your MIDI file and open it in your music software. Select an instrument to play the notes.
03 — Voice and instruments
Bring your musical ideas into MIDI
Voice to MIDI: singing, vocals and humming
A voice recording to MIDI workflow lets you save a tune before an instrument is nearby. For singing to MIDI or humming to MIDI, record one steady melodic line with short gaps between phrases. You can then play the idea with a piano or synth.
For vocal to MIDI from a finished song, isolate the lead vocal first. A clear voice makes the melody easier to check; breath sounds and vibrato may need a few note edits.
Piano to MIDI, guitar to MIDI and bass to MIDI
Piano
Recover a melody or chord idea. Clear attacks and less reverb make overlapping notes easier to review.
Guitar
Capture a picked melody or clean riff. Check slides, bends and vibrato, then choose the notes for your new instrument.
Bass
Double a recorded bass line with a synth. Use an isolated take and check long, overlapping low notes.
04 — Edit and arrange
From a recording to your next arrangement
Melody to MIDI and song to MIDI
For music to MIDI, choose the part you want: a lead melody, bass line or piano phrase. To convert a song to MIDI with a clearer focus, isolate that instrument first. Separate stems help you extract notes from audio for individual parts of an arrangement.
Polyphonic audio to MIDI captures notes sounding together, such as chords. Review those overlapping notes as a group. The download contains one editable sequence; convert stems individually to arrange them on separate tracks.
Preview, edit MIDI notes and export MIDI
The MIDI note editor lets you change pitch, start time, length and velocity. Longer piano-roll blocks mean longer notes; stacked blocks play together. Start with Balanced detection, then compare More notes or Fewer notes if the result needs adjusting.
When you export MIDI, BPM sets the beat grid while preserving the original note timing. To change the groove, quantize the notes in your music software after importing.
Use your MIDI in music software
Save the edited .mid file and bring the melody into your project. Assign a virtual instrument, then review the tempo and note placement.
MIDI for FL Studio
Drag the file into a channel's piano roll or use MIDI import.
MIDI for Ableton Live
Drag the file onto a MIDI track and load an instrument.
MIDI for Logic Pro
Import the file or drag it into the Tracks area.
MIDI for Cubase
Use Import MIDI File and choose the destination tracks.
MIDI for Studio One
Drag the file into the arrangement and assign an instrument.
05 — FAQ
Audio to MIDI FAQs
Is audio to MIDI free, with no signup?
Yes. Upload a supported recording, preview and edit the notes, then download the MIDI. No account is required.
How do I choose the best audio to MIDI converter?
Compare the detected melody with your original recording. Look for correct pitches, useful note lengths, editable results and an export that opens in your music software.
Can I convert MP3 to MIDI online?
Yes. Upload the MP3 and review the detected notes. Conversion transcribes the music; renaming the file extension does not create MIDI notes.
Can I convert WAV to MIDI online?
Yes. Use a clear instrument take or isolated stem. Review sustained and overlapping notes before exporting.
Why does my voice or guitar sound like piano?
The piano preview plays the detected melody. Musical audio transcription creates note instructions; the original tone and lyrics remain in the audio. Choose another instrument after importing the MIDI.
Can I use audio to MIDI for sheet music?
Open the exported MIDI in notation software such as MuseScore Studio. Review the time signature, note values, rests and overlapping parts there.
Can I use audio to MIDI on mobile?
Yes. Open the page in your mobile browser, select a saved recording and download the MIDI after reviewing it.
Can I use audio to MIDI without installing software?
Yes. Conversion, piano playback and note editing are available on this page. Download the result whenever you are ready to use it in another project.
How long does conversion take?
Processing time depends on the recording's length and current demand. Keep the tab open until the notes appear; you can cancel an ongoing conversion.
How do I fix extra or missing notes?
Compare the preview with your recording, try a different detection setting, then add or remove notes in the editor. An isolated instrument and less reverb make the part easier to review.
