FM SYNTH

simple frequency modulation synthesizer

Installation

Node.js

npm install @mohayonao/fm-synth

Browser

• fm-synth.js

API

Operator

• constructor(algorithm: number|string, operators: any[])

Instance attribute

• context: AudioContext
• operators: any[]
• algorithm: string
• onended: function

Instance methods

• connect(destination: AudioNode): void
• disconnect(): void
• start(when: number): void
• stop(when: number): void

Algorithm Notation

let A = audioContext.createDelay();
let B = new Operator(audioContext);
let C = new Operator(audioContext);
let D = new Operator(audioContext);
let fm = new FMSynth("E-D-C->; B-A->", [ A, B, C, D, 0 ]);

• A, B, C ... Z: index of the operators
• -: connection (connects to a node's frequency or node self if not has frequency)
• >: connection to output
• ;: separator
• 0 in operators mean OFF. Those are ignored in the audio graph.

Now, the instance of FMSynth builds the below graph by the given algorithm "D-C->; B-A->".
