HUMMED MELODY WORKFLOW

Convert Humming to MIDI

Hum one clear note at a time, leave a definite change between notes, and record in a quiet place. Use the microphone button below or upload a saved recording. The converter detects one pitch at each analysis moment, so harmony, backing music, strong echo, and continuous pitch slides can create unwanted or broken notes.

Four-step humming-to-MIDI capture and testing workflow
Record a clean single-note melody first; use controls to refine a repeatable result, not to repair overlapping sounds.

PROCESS ON THIS DEVICE

Record or upload a hummed melody

Use one short phrase for the baseline, then repeat that same phrase when testing a control.

SOURCE

Hum one pitch at a time

The detector estimates one frequency or no frequency for each analysis frame. Chords and doubled voices do not become separate simultaneous MIDI tracks here.

TRANSITIONS

Clean attacks make clearer boundaries

A long glide passes through many intermediate pitches. Hold the vowel steady, then make a deliberate change when the next note begins.

NOISE TEST

Separate breath from duration

Threshold filters quieter frames; Minimum note filters short detected events. Test them separately so the result shows which change mattered.

EVIDENCE

Compare the same phrase

Keep the melody, distance, room, and device fixed. Compare note blocks and audible preview before keeping any control change.

QUICK ANSWERS

Humming-to-MIDI questions

Can I convert humming to MIDI?

Yes. Record or upload a clear single-note hummed melody, convert it in the browser, preview the detected notes, and download the result as a .mid file.

Does the page upload my voice?

No. The recording or selected file is decoded and analyzed in this browser and is not uploaded to a server.

Why does a smooth pitch slide create extra MIDI notes?

A slide contains changing pitch over time. Re-record with steadier target notes and clearer transitions before changing the detection controls.

How do I remove breath sounds from the MIDI?

Hold the recording fixed and raise Silence threshold one step. If the unwanted notes are brief rather than quiet, revert and test Minimum note separately.

Can it convert harmonized humming?

This page estimates one pitch at each analysis moment, so use one melodic line without harmony or backing music for a result that matches the tool's design.
