Why is a WebAudio metronome more accurate than standard JavaScript setInterval?

Standard setInterval/setTimeout timers in JavaScript are subject to event-loop jitter, garbage collection pauses, and aggressive background tab throttling. The WebAudio API uses the browser's dedicated real-time audio thread (audioContext.currentTime) for sample-accurate scheduling.

How many taps are needed for an accurate BPM measurement?

While 4 taps provide a rough estimate, tapping steadily for 8 to 16 beats produces an accuracy within 0.1 BPM, compensating for human motor timing variation.

What are delay milliseconds used for in audio production?

Producers use delay times (e.g. 1/4 note ms = 60,000 / BPM) to synchronize stereo delay effects, compressor release times, and synthesizer LFO rates to the groove of the track.

Can I adjust the tempo manually without tapping?

Yes, you can fine-tune the BPM slider or type an exact tempo value to test custom speeds instantly.
