节拍器

一款精确的 Web Audio 节拍器，可设置速度、每小节拍数和细分。您的设置会被记住。

This browser does not provide the Web Audio API, so the metronome cannot run.

使用方法

Set the tempo (30–240 BPM) with the slider, or tap the Tap tempo button a few times in rhythm.
Choose beats per bar (2–8) and a subdivision (quarter, eighth, triplet, sixteenth).
Press Start; the first beat of each bar clicks at a higher pitch.

注意事项

Clicks are scheduled ahead of time against the Web Audio clock (a 25 ms scheduler reserving 0.1 s ahead), so the tempo stays stable even when the tab is busy. Your tempo, beats and subdivision are saved in this browser's localStorage and restored on your next visit.

常见问题

What does the triplet subdivision do?: It clicks three evenly spaced notes per beat, for practicing eighth-note triplets and similar patterns.
How accurate is tap tempo?: It averages the intervals of your taps within the last 2 seconds. Four or more taps give a stable result.
