Do I need special hardware?
No. Humming runs entirely in modern browsers. A built-in laptop mic works for pitch tracking, but an audio interface will yield the cleanest harmonies.
Browser-based vocal harmony lab
Humming pairs accurate pitch analysis with a responsive harmony engine so you can test third, fourth, and fifth intervals, rehearse choir parts, or audition background vocals in minutes.

On-device processing
Everything runs in the browser via WebAudio so creative work stays fast, private, and installation-free.
Introducing the interface
Humming's workspace mirrors a DAW timeline without the setup overhead. Visual guidance, responsive controls, and contextual tips keep you in the creative flow whether you're rehearsing choir parts or sketching backing vocals.

Layered workspace
Separate vocal, harmony, and reference lanes keep your edits organized while you experiment with stacked intervals.
