Overview

XSound gives Web Developers Powerful Audio Features Easily !
In concrete, XSound is useful to implement the following features.

• Create Sound
• Play the One-Shot Audio
• Play the Audio
• Play the Media
• Streaming (by WebRTC)
• MIDI (by Web MIDI API)
• MML (Music Macro Language)
• Effectors (Compressor / Wah / Equalizer / Tremolo / Phaser / Chorus / Delay / Reverb ... etc)
• Visualization (Overview in Time Domain / Time Domain / Spectrum)
• Multi-Track Recording (Create WAVE file)
• Session (by WebSocket)
• Audio Streaming
• Visual Audio Sprite

XSound don't depend on other libraries or frameworks (For example, jQuery, React).

Getting Started

In case of using as full stack (For example, use oscillator) ...

X('oscillator').setup([true, true, false, false]).ready(2, 5).start([440, 880]).stop();

or, in case of using as module base (For example, use chorus effector) ...

// The instance of `AudioContext`
const context = X.get();

// Create the instance of `Chorus` that is defined by XSound
const chorus = new X.Chorus(context);

const oscillator = context.createOscillator();

// The instance that is defined by XSound has connectors for input and output
oscillator.connect(chorus.INPUT);
chorus.OUTPUT.connect(context.destination);

// Set parameters for chorus
chorus.param({
  time : 0.025,
  depth: 0.5,
  rate : 2.5,
  mix  : 0.5
});

// Activate
chorus.activate();

oscillator.start(0);

XSound enable to using the following classes (Refer to API Documentation for details).

// These type aliases are defined by XSound
type BufferSize = 0 | 256 | 512 | 1024 | 2048 | 4096 | 8192 | 16384;
type RecordType = 1 | 2;  // Monaural | Stereo

X.Analyser(context: AudioContext);
X.Recorder(context: AudioContext, bufferSize: BufferSize, numberOfInputs: RecordType, numberOfOutputs: RecordType);
X.Session(context: AudioContext);

// Effectors
X.Autopanner(context: AudioContext);
X.Chorus(context: AudioContext);
X.Compressor(context: AudioContext);
X.Delay(context: AudioContext);
X.Distortion(context: AudioContext);
X.Equalizer(context: AudioContext);
X.Filter(context: AudioContext);
X.Flanger(context: AudioContext);
X.Listener(context: AudioContext);
X.NoiseGate(context: AudioContext);
X.NoiseSuppressor(context: AudioContext, size: BufferSize);
X.Panner(context: AudioContext);
X.Phaser(context: AudioContext);
X.PitchShifter(context: AudioContext, size: BufferSize);
X.Reverb(context: AudioContext);
X.Ringmodulator(context: AudioContext);
X.Stereo(context: AudioContext, size, size: BufferSize);
X.Tremolo(context: AudioContext);
X.VocalCanceler(context: AudioContext, size: BufferSize);
X.Wah(context: AudioContext);

Demo

XSound.app uses this library.

Now, I'm creating website for Web Audio API. Please refer to the following site for understanding API Documentation.

WEB SOUNDER

Installation

$ npm install --save xsound

or,

$ yarn add xsound

Usage

In case of using CDN,

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/xsound@latest/build/xsound.min.js"></script>

In case of using ES Modules (for SSR ... etc),

import { XSound, X } from 'xsound';

Connect to WebSocket Server

const roomId = 'test-room-id-001';  // Any string

// for `ScriptProcessorNode`
const bufferSize             = 2048;
const numberOfInputChannels  = 2;
const numberOfOutputChannels = 2;

const analyser = X('stream').module('analyser');

// for connecting to WebSocket server
const tls  = true;  // Use `wss:`
const host = 'xsound-websocket-server.herokuapp.com/';
const port = 8000;
const path = '/app';

const setupParams = {
  roomId,
  bufferSize,
  numberOfInputChannels,
  numberOfOutputChannels,
  analyser
};

const connectionParams = {
  roomId,
  tls,
  host,
  port,
  path
};

// For example, sound source is `StreamModule`
X('stream')
  .module('session')
  .setup(setupParams)
  .ready(connectionParams);

Setup

Use Webpack Dev Server

$ git clone [email protected]:Korilakkuma/XSound.git
$ cd XSound
$ npm install
$ npm run dev
$ open http://localhost:8080/playground/

Use Docker

$ git clone [email protected]:Korilakkuma/XSound.git
$ cd XSound
$ npm install
$ npm run watch
$ docker compose up -d --build
$ open http://localhost:8080/playground/

API Documentation

XSound API Documentation

Playground

XSound Playground (Watch by YouTube).

Migration to v3

Please refer to API Documentation for details.

Case sensitive

// Bad (v2 or earlier)
X('audio').module('panner').param({ coneinnerangle: 240 });

// Good (v3)
X('audio').module('panner').param({ coneInnerAngle: 240 });

Use plain object if parameters setter

// Bad (v2 or earlier)
X('oscillator').get(0).param('type', 'sawtooth');

// Good (v3)
X('oscillator').get(0).param({ type: 'sawtooth' });

Validate parameters on the application side

if ((type === 'sine') || (type === 'square') || (type === 'sawtooth') || (type === 'triangle')) {
  X('oscillator').get(0).param({ type });
}
