Elementary is a JavaScript/C++ library for building audio applications.
The @elemaudio/web-renderer package provides a specific Renderer implementation
for running Elementary applications in web environments using WASM and Web Audio. You'll
need to use this package alongside @elemaudio/core to build your application.
Please see the full documentation at https://www.elementary.audio/
npm install --save @elemaudio/web-rendererimport { el } from '@elemaudio/core';
import WebRenderer from '@elemaudio/web-renderer';
// Note that many browsers won't let you start an AudioContext before
// some corresponding user gesture. We're ignoring that in this example for brevity,
// but typically you would add an event callback to make or resume your
// AudioContext instance in order to start making noise.
const ctx = new AudioContext();
const core = new WebRenderer();
(async function main() {
// Here we initialize our WebRenderer instance, returning a promise which resolves
// to the WebAudio node containing the runtime
let node = await core.initialize(ctx, {
numberOfInputs: 0,
numberOfOutputs: 1,
outputChannelCount: [2],
});
// And connect the resolved node to the AudioContext destination
node.connect(ctx.destination);
// Then finally we can render
core.render(el.cycle(440), el.cycle(441));
})();MIT
