This metronome uses the Web Audio API with a lookahead scheduling mechanism. Traditional setInterval loops in JavaScript can suffer from timing drift due to the single-threaded nature of the event loop. By scheduling future notes ahead of time directly on the audio context, we achieve sample-accurate timing regardless of main thread blockage.
