PEAKD

Catch the peak, not the ending.

PEAKD is a listening and timing game. Generated sounds last 3–5 seconds. Daily may also feature a hand-picked audio clip up to 15 seconds long. Unlimited always generates a new sound.

You get exactly one Listen playback, then one Challenge playback. During Challenge, only the part of the waveform already played is visible. Click or tap Stop, or press Space. After finishing, the entire waveform, actual peak and your stop appear. Replay is available only after the result.

What counts as the peak?

The target is the center of the loudest 50-millisecond RMS window, not a single sample spike. Equal windows use the earliest peak. Your signed error is your stop time minus the peak time: negative means early, positive means late.

Your score falls linearly from 1000 at the peak to 0 at 1 second off, rounded to the nearest point. A 100 ms error scores 900; 500 ms scores 500; 750 ms scores 250. Not stopping scores 0. Start at a comfortable volume.

The finish popup shows your score-based tier. Your tier appears above the result waveform. Daily results include a chart counting all completed ranked players in each tier, highlighting your tier; Unlimited shows the score thresholds instead. No stop earns Wood. Tiers do not change rankings.

Share result shares or downloads a spoiler-free PNG; Copy result copies that image where supported. The card includes your score, milliseconds off and tier, but never the real waveform or peak/stop positions.

One chance, wherever you play

Daily results enter the Daily, season and global rankings without signing in. A random browser ID keeps your attempts together; use Player name to choose or change your public name. Linking an account imports non-overlapping guest results. Listen starts your one chance. Reloading, leaving the tab or interrupting audio during a round consumes that chance for zero; it cannot restart the preview. Switch modes before starting or after finishing.

Use your device speakers or wired headphones for the most consistent timing. Bluetooth and device latency can affect results. Set a comfortable volume before starting; do not turn it up to chase a score.
