Sing any note and the AI will name it — like a super-ear! It works by measuring the frequency of your voice (how fast it wiggles) and matching it to a musical note. This is how tuning apps and auto-tune work.
Turn on your mic and hum or sing a steady note. The big letter is the note you're singing; the needle shows if you're a little flat (left) or sharp (right). Try to slide up and down!
The AI shows a target note. Sing it (or tap the test note) and hold it steady until the bar fills. Hit 3 targets to win!
You built a super-ear that names any pitch — just by measuring frequency. Now you understand tuners, auto-tune, and how AI finds the melody in a sound.
