Lightweight sound synthesizer designed for real-time user interaction using the Web Audio API
Example
const context = new AudioContext({latencyHint: 'interactive'});
const synth = new Synth(context, context.destination);
synth.maxPolyphony = 6;
synth.voiceParams = defaultParams();
const noteOffs = new Map<string, () => void>();
window.addEventListener('keydown', (event: KeyboardEvent) => {
const pitch = parseInt(event.key, 36) % 24;
const frequency = 440 * 2 ** (pitch / 12);
const velocity = 0.2;
noteOffs.set(event.key, synth.noteOn(frequency, velocity));
});
window.addEventListener('keyup', (event: KeyboardEvent) => {
if (noteOffs.has(event.key)) {
noteOffs.get(event.key)!();
}
});
