Frequently Asked Questions
How accurate is this tap tempo counter?
The tap tempo counter uses the high-precision browser performance.now() API (accurate to fractions of a millisecond) and computes a rolling mathematical average of your last 8 intervals, delivering sub-BPM precision.
Does the metronome require internet access or sound files to work?
No. The metronome synthesizes wooden woodblock and beep sounds mathematically in real time using the native HTML5 Web Audio API, functioning completely offline without loading any external sound files.
