The fastest way to capture a melody is to hum it. A humming to MIDI converter turns that quick vocal idea into real notes you can drop into any instrument — no need to play it on a keyboard first.

Record a hummed idea without leaving the page
Press Record a melody and allow microphone access when your browser asks. Hum one phrase, then press Stop recording. Recording stops automatically after 60 seconds. Cancel recording discards the take and releases the microphone; leaving the page also stops recording.
If access is denied or recording is unavailable, use a voice memo from your phone instead. Save it as an audio file and choose it here. Microphone permission is only needed for recording on this page, not for converting an existing file.
Check the phrase before converting
Use the waveform to locate your melody, then set Start and End in seconds. Listen to selection before converting. Keep the start of the first note and the end of the last note inside the range. Use full recording restores the whole take if you cut too much.
The selection does not remove gaps between notes. Those pauses may be part of your rhythm. MIDI note times are measured from the start of your selection: a note at 13 seconds in a selection starting at 12 seconds appears at about one second. The MIDI may end before the selection does if there is silence after the last detected note.
Listen, adjust, and try the same take again
Compare Original audio and Raw MIDI after conversion. Both refer to the same selected phrase. Listen for the shape of the melody and repeated notes before fixing every small difference. The synthesized preview uses a simple instrument sound; it does not reproduce your voice.
Choose Adjust & re-convert if notes are missing or there are too many extra notes. Your recording stays loaded, and the settings are available again. Lower Note confidence slightly for a quiet phrase; raise it for unwanted background pitches. If short notes disappear, reduce Min note length. Change one setting at a time so you can hear what helped.
Use Record a melody to capture up to 60 seconds here, or choose a saved voice memo. The Voice profile is already selected. Listen to your take, choose the phrase you want, then convert it to MIDI. One clear hummed line is easier to transcribe than a voice over a backing track.
Record the idea here
Start a short microphone recording without leaving the converter. Stop and listen before deciding which phrase to turn into notes.
Work on one phrase
Select the part you need. The converter keeps pauses inside the phrase, and you can return to adjust the selection after hearing the MIDI.
Clean up with settings
Hummed takes can be breathy — raise the thresholds and minimum note length in Advanced settings for a tidy single-line melody.

Humming to MIDI — FAQ
How do I use a humming to MIDI converter?
Record a melody here or choose an M4A, MP3 or WAV voice memo. Select and listen to a phrase, press Convert selection to MIDI, then preview and download the free Raw MIDI.
Can I record with my microphone?
Yes, in a browser that supports microphone recording. Press Record a melody and grant permission. Takes stop after 60 seconds. If recording is unavailable, choose a saved voice memo instead.
Why are there wrong or extra notes?
Sliding between pitches and breath noise can add stray notes. Hum more deliberately, and increase onset/note confidence and minimum note length in Advanced settings.
Can I hum chords?
Humming is one note at a time, so you get a single-line melody. For chords, record an instrument like piano or guitar instead.
