How Humonica works
A hum is just pitch over time. Humonica measures that pitch, turns it into notes you can edit, and plays those notes back on a real instrument sound — without ever sending your voice anywhere.
STEP 01
You record or upload
Hum, sing or whistle into the mic, or drop in a voice memo (WAV, MP3, M4A, AAC, OGG, Opus, FLAC, WebM, AMR, 3GP). A live level meter and one-tap room calibration help you land in the right volume range before you commit to a take.
STEP 02
Humonica hears the notes
The clip is cleaned up — DC removal, high-pass, noise gate, automatic gain — then pitch-tracked frame by frame. You get a colourful waveform of your take plus the detected key, tempo and note count, stated plainly.
STEP 03
You choose the sound
Pick from fourteen instruments — piano, electric piano, guitar, strings, violin, cello, trumpet, sax, flute, music box, synth lead, marimba, steel drums or a drum kit — then set key, tempo, transpose and snap-to-key to taste.
STEP 04
You play it and take it
Preview the rendered arrangement, then download WAV or MP3 audio, or a MIDI file for your DAW.
STEP 05
Advanced Mode — coming soon
The deeper tools live in Advanced Mode: the pitch-detection graph, confidence readouts for key, tempo and notes, the piano roll and note editor with undo, redo and A/B loop, noise-reduction presets with before/after diagnostics, five-minute takes, and MusicXML plus printable PDF score exports.
Your voice never leaves the device
Recording, pitch detection, rendering and every export run inside your browser. There is no upload, no account and no stored audio.
Works best with
- One note at a time — a hummed, sung or whistled line
- A steady "la" or "doo", or a clear whistle tone
- 8–30 seconds, roughly a hand's width from the mic
- A quiet room with no backing track or chatter
Struggles with
- Chords, harmonies or two people at once
- Singing over a track playing in the background
- Very breathy, whispered or distorted takes
