Quick Start

This is the minimal graph to synthesize a tone:

ts

import { AudioContext } from '@nativescript/audio-context';

const ctx = new AudioContext({ latencyHint: 'interactive' });

const osc = ctx.createOscillator({ type: 'sine', frequency: 440 });
const gain = ctx.createGain({ gain: 0.12 });

osc.connect(gain);
gain.connect(ctx.destination);

await ctx.resume();
osc.start();

setTimeout(async () => {
  osc.stop();
  await ctx.close();
}, 1200);

Lifecycle notes

Call resume() before playback.
Stop sources when done.
Call close() to release resources.
