About Metronome – Free Interactive Online Tempo & Beat Generator
Free online metronome for musicians, producers, and practice. Features precise Web Audio API timing, visual beat LEDs, animated pendulum, custom time signatures, tap tempo, sound synthesis, and zero captcha requirements.
What is an Online Metronome?
An online metronome is a precision timekeeping tool used by musicians, drummers, and producers to maintain a steady tempo during practice. It generates audible click pulses at exact Beats Per Minute (BPM) intervals.
Why use Web Audio API for Metronome Timing?
Traditional JavaScript timers (like setInterval or setTimeout) suffer from timing jitter when browser tabs background or handle main thread tasks. Our online metronome uses the Web Audio API hardware clock scheduler for microsecond-accurate click timing without drift.
How to use Tap Tempo & Beat Accents
Use the BPM slider or +/- buttons to dial in exact speeds from 20 to 300 BPM. Click "Tap Tempo" to match any live rhythm automatically, select time signatures (2/4, 3/4, 4/4, 6/8, 5/4), and watch the animated visual pendulum swing in real time.
📐 Methodology & Reference Accuracy:
Calculations, formulas, and conversions execute locally in your web browser. Output models are benchmarked against official reference standards and updated for 2026.
