How it works
Your voice is the stick
Hum a higher note and the plane climbs. Hum lower and it dives. Stop humming and it glides gently down. Once you are flying, your hands are free.
Tuned to your range
A ten-second warm-up finds your lowest and highest comfortable notes. Deep or high, the whole sky fits your voice, and every gap sits on a real note in it.
Listening stays on your device
Pitch is worked out in your browser, 60 times a second. No sound is recorded, uploaded or saved.
Works best with headphones or speakers turned down, in a quiet room. A fan right next to the microphone makes the plane glide more, because it can hear you less.
What testing changed
Every version of the pitch tracker was scored on synthetic hums from four voices (deep to high), every note in their range, clean and with room noise. A frame counts as a wrong note when the pitch steering the plane is more than half a semitone off the note being hummed.
