節拍器

一款精確的 Web Audio 節拍器，可設定速度、每小節拍數和細分。您的設定會被記住。

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.

注意事項

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.

常見問題

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.
