About Sound Memory Trainer

Audio version of the classic Simon — four pads play tones in a sequence and you must repeat the order. Pick from three sound packs: Piano (sine waves), Pixel (square waves), and Sci-Fi (saw waves). Built with the Web Audio API, so you can play with your eyes closed and rely on hearing alone.

How to Use

  1. 1Pick a sound pack.
  2. 2Click Start. Listen to the tone sequence as the pads light up.
  3. 3Repeat the sequence by clicking the pads in the same order.
  4. 4Each correct round adds one tone to the sequence.
  5. 5Try playing with your eyes closed — pure ear training.

Frequently Asked Questions

What are the sound packs?
Piano uses pure sine tones for a soft sound. Pixel uses square waves for a retro 8-bit feel. Sci-Fi uses sawtooth waves for a sharper, futuristic timbre.
Can I play without looking?
Yes. Each pad has a unique pitch, so once you learn the four tones you can repeat sequences entirely by ear. Great for training auditory working memory.
Why does my browser need to load before sound plays?
Browsers require a user gesture before audio can start. The first click on Start unlocks the AudioContext.
