Sing higher to steer up. Sing lower to steer down. Dodge the roadblocks, collect music notes, and chase a place on the leaderboard.
Pitch Racer is a fully free voice game that turns your microphone into a game controller. It estimates the fundamental frequency of your voice directly in the browser, then maps higher and lower notes to the car’s position on the track.
You do not need to be a singer. Humming, whistling, or holding a vowel all work—as long as the sound has a clear, steady pitch.
Your browser needs permission to hear live pitch. Nothing is recorded or uploaded.
Start with a comfortable “oooh” or hum. Your first stable note becomes the center of the track.
Raise your pitch to move toward the top and lower it to move toward the bottom.
Avoid barriers, collect notes for bonus points, then save your score and retry.
Smooth changes in pitch make the car easier to control than sudden octave jumps.
The game follows frequency rather than volume. A relaxed, consistent sound works best.
Use a quiet room or headset microphone so music and other voices do not confuse detection.
It uses the Web Audio API to analyze short audio frames and estimate their repeating waveform frequency. That frequency is converted into a smooth vertical position for the car.
It is pitch controlled. Singing louder will not move the car higher; singing a higher musical note will.
No. This game analyzes the microphone stream locally in your browser. It does not create an audio recording or send your voice to the server.
Use a sustained “oooh,” hum, or whistle rather than speech. Check microphone permission, reduce background noise, and keep a consistent distance from your microphone.
Yes. Modern mobile browsers support microphone controls. You can also drag vertically on the game area if microphone access is unavailable.
