audio-lab

Audio-lab is a sound design & music ideas sharing application.

Use cases

• Save a melodic motive, in abstract form (dependless of specific sound). To share it later or to use in a track.
• Export/import midi-files
• Save/load projects, ideally as a github repo. Because each project may consist of multiple lab files, like grooves, synth preset etc.
• Import/export web-audio code setup
• Share musical pieces easily

Principles

• Keep blocks atomic, in that separate midi/piano blocks are better than single compound one. Ideally, scheme of generated sound should be clear from the bird’s eye view.
• No modes of blocks (consequence of previous principle).
• No time concept. Everything sounds just as project loads. There is no trigger in reality.
• Any block can be based off a script processor block, putting calculations to any stream/async mode.
• Any block can be "rendered" to audio-buffer block to enhance performance.
• Fx-es, gain and stats should be available on blocks and on connections.
• Touch-oriented interface.
• Lab manages blocks, blocks manages connections. Though connections and blocks are self-sufficient units. Blocks and connections know nothing about lab (as people about god).

Docs

Init lab

var Lab = require('audio-lab');
 
var lab = new Lab({
    element: document.querySelector('.lab-container'),
    context: audioContext,
    channels: 2,
    autosave: false
});

Create block plugin

var Lab = require('audio-lab');
 
class Piano extends Lab.Block {
    constructor (options) {
        super(options);
 
        //init here
 
        this.state = 'ready';
    }
}
 
//name to use as a node name
Piano.displayName = 'Piano';
 
Piano.prototype.numberOfInputs = 0;
Piano.prototype.numberOfOutputs = 1;

Use plugin

var Lab = require('audio-lab');
var Piano = require('audio-lab-piano');
 
var lab = new Lab();
lab.use(Piano);
