Hum to MIDI review
A free browser tool for capturing single-line melodies as MIDI, not generating full songs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Hum to MIDI is a free browser utility for turning a hummed, sung, or whistled single-line melody into MIDI notes as it is performed. It suits solo musicians and small teams who want to capture a melodic idea without first entering it by hand. The piano-roll display shows detected notes in real time, and the tool includes playback and a demo mode. This is a focused melody-capture tool, not a generator for complete songs or arrangements.
Its useful controls center on pitch capture and export. Notes can be snapped chromatically or to a detected key, and detection sensitivity is adjustable. Export tempo can also be set before downloading a standard .mid file, which can be brought into DAWs or notation software. That MIDI handoff makes the tool relevant when the next step is arranging or editing elsewhere; it does not itself provide notation export or finished audio output. Choose it when a vocal idea needs to become editable MIDI, rather than when the goal is an automatically produced track.
The browser-based workflow avoids installing a desktop app, and the site says microphone audio is processed locally and never uploaded. It uses autocorrelation for pitch detection, with no AI model involved, so the “AI Hum-to-Song” category label should not be read as a claim that this tool generates music with AI. Its narrow scope and basic pitch controls are the main tradeoffs. Hum to MIDI is a sensible fit for quick, privacy-conscious melody capture; creators seeking full-song generation, richer production tools, or notation output should look elsewhere.
