speaker

node-speaker

Output raw PCM audio data to the speakers

A Writable stream instance that accepts raw PCM audio data and outputs it to the speakers. The output is backed by mpg123's audio output modules, which in turn use any number of audio backends commonly found on Operating Systems these days.

Installation

Simply compile and install node-speaker using npm:

$ npm install speaker

Example

var Speaker = require('speaker')

// Create the Speaker instance
var speaker = new Speaker({
  channels: 2,          // 2 channels
  bitDepth: 16,         // 16-bit samples
  sampleRate: 44100     // 44,100 Hz sample rate
});

// Raw PCM data from stdin gets piped into the speaker
process.stdin.pipe(speaker);
