Package Exports

node-web-audio-api
node-web-audio-api/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (node-web-audio-api) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

`node-web-audio-api`

Nodejs bindings for orottier/web-audio-api-rs using napi-rs

Install

npm install [--save] node-web-audio-api

Example

import { AudioContext, OscillatorNode, GainNode } from 'node-web-audio-api';

const audioContext = new AudioContext();

setInterval(() => {
  const now = audioContext.currentTime;

  const env = new GainNode(audioContext);
  env.connect(audioContext.destination);
  env.gain.value = 0;
  env.gain.setValueAtTime(0, now);
  env.gain.linearRampToValueAtTime(1, now + 0.02);
  env.gain.exponentialRampToValueAtTime(0.0001, now + 1);

  const osc = new OscillatorNode(audioContext);
  osc.frequency.value = 200 + Math.random() * 2800;
  osc.connect(env);
  osc.start(now);
  osc.stop(now + 1);
}, 50);

Build manually

If prebuilt binaries are not shippped for your platform, you will need to install the rust toolchain and install and build the package from github.

Install rust toolchain

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Install from github

npm install --save git+https://github.com/b-ma/node-web-audio-api.git

Note that the package will be built on your machine, so the install process might be a bit long

Roadmap

Make a few nodes work properly with clean and predictable code
Generate bindings from IDL https://webaudio.github.io/web-audio-api/#idl-index
Publish on npm with binaries
Implement prototype chain (?)
Follow developments of web-audio-api-rs
