How sharp are your ears?
Sound Game plays a tone, then challenges you to recreate it from memory using a frequency slider. No notation. No multiple choice. Just
you, a sound, and your perception.
Each round, a tone between 80 Hz and 1400 Hz plays for 3 seconds. When it stops, slide to match what you heard. Your score is calculated
using psychoacoustic distance — the closer you come on the ERB scale (how your ears actually perceive pitch), the higher you score.
It's a pure, honest test of your hearing. No tricks, no fake difficulty curves, no pay-to-win. Five tones, one score, shareable. That's
it.
WHY IT'S DIFFERENT
• No multiple choice — guess anywhere on the spectrum
• Psychoacoustic scoring, not raw Hertz math
• Layered synth with detuned pairs, fifths, octaves, and a sub for real tonal warmth
• Haptics + sound design tuned for flow
• Minimalist, dark-only interface with animated waveform visuals
MODES
• 5-round game with cumulative scoring and personal-best tracking
• 1-round quick game for fast practice
• Easy (80–1200 Hz) and Hard (60–1400 Hz) difficulty
WHO IT'S FOR
• Musicians doing ear training
• Audio engineers checking their frequency recognition
• Curious listeners who want to know how good their ears really are
• Anyone who enjoys beautifully crafted, focused games
PRIVACY
• No accounts, no tracking, no analytics
• Works 100% offline
• No ads, no in-app purchases
• Local-only high-score tracking
Headphones strongly recommended — the synth's harmonic layers get lost on phone speakers.
