Elementary is a JavaScript/C++ library for building audio applications.
The @elemaudio/offline-renderer package provides a specific Renderer implementation
for running Elementary applications in Node.js and web environments using WASM. Offline
rendering is intended for processing data with no associated real-time audio driver, such
as file processing. 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/offline-rendererimport { el } from '@elemaudio/core';
import OfflineRenderer from '@elemaudio/offline-renderer';
(async function main() {
let core = new OfflineRenderer();
await core.initialize({
numInputChannels: 0,
numOutputChannels: 1,
sampleRate: 44100,
});
// Our sample data for processing: an empty input and a silent 10s of
// output data to be written into.
let inps = [];
let outs = [new Float32Array(44100 * 10)]; // 10 seconds of output data
// Render our processing graph
core.render(el.cycle(440));
// Pushing samples through the graph. After this call, the buffer in `outs` will
// have the desired output data which can then be saved to file if you like.
core.process(inps, outs);
})();MIT
