Frequently Asked Questions
How does the Online Metronome work?
The metronome uses the Web Audio API to create short oscillator bursts on each beat, scheduled ahead of time with AudioContext.currentTime for sample-accurate timing. A lookahead scheduler queues beats into the audio pipeline so the click stays rock-solid even when the browser is busy rendering or running JavaScript.
How accurate is the online metronome?
The metronome uses the Web Audio API for sample-accurate scheduling, the same technology used in professional audio applications. It maintains precise timing even if the browser is under load.
Can I change the time signature?
Yes. Set any time signature including common ones like 4/4, 3/4, 6/8, and custom values. The accent pattern adjusts automatically to match your time signature.
Does it work on my phone?
Yes. The metronome works on mobile browsers. Make sure your phone is not in silent mode, as some mobile browsers respect the hardware mute switch.
