/wave-generator

Generates Sine, Triangle, Sawtooth and Square waveforms

Primary LanguageJavaScriptMIT LicenseMIT

Installation

npm install wave-generator --save

API

All

Parameters

  • size: Generated array size
  • f: wave frequency
  • fs: sample frequency
  • [amplitude = 1]
  • [useCounter = true]: If false all calls will start from the beginning of the array, true (default) will give continuous data

Sawtoothwave

Extra Parameters

  • [inverted = false]: Sawtooth direction |\|\ or /|/|

Usage

// import constructors
const { Sinewave, Squarewave, Trianglewave, Sawtoothwave } = require('wave-generator')

const sine440 = Sinewave(2048, 440, 44100, 30)

console.log(sine440(100)) // Array with 100 points
console.log(sine440(100)) // Array with the next 100 points

const square220 = Sinewave(2048, 220, 44100, 20, false)

console.log(square220(100)) // Array with 100 points
console.log(square220(100)) // Array with the same 100 points
