A click that keeps time: BPM, bar length and subdivision from eighth notes to sixteenths, with a lookahead scheduler so the tempo never drifts with the frame rate. 120 BPM is a beat every 500 ms exactly, and each eighth is 250 ms.
Clicks are scheduled ahead of time against the AudioContext clock, so the tempo does not drift with the frame rate. The downbeat is a higher, louder tick than the rest.
