sox-play

node module to play sound files via sox's play command

You will need to install sox before use.

If you want to use MP3 files, you will also need libsox-fmt-mp3

Usage

var AudioPlayer = require('sox-play');
 
var player = new AudioPlayer({file:'/home/pixnbits/Music/birds.ogg'}); // http://www.portal2sounds.com/2265
 
player.on('start', function(filePath){
  console.log('started playing', filePath);
});
 
player.on('status', function(status){
  console.log('status! ', status.position);
  /*
  status: {
    loaded: 0-1 (%)
    position: PlayerPosition instance (see below)
    remaining: PlayerPosition  instance
    dataPlayed: strings like '14k'
  }
  PlayerPosition : {
    hours
    minutes
    seconds
    frac
  }
  */
});
 
player.on('stop', function(filePath){
  console.log('stopped playing', filePath);
});
 
player.play();

In addition, you can use an interpolated position whenever you want:

console.log('guessing position:', player.guessPosition());

The guess is simply the last reported position plus whatever time has transpired since then.

You can also stop easily:

player.stop(); // SIGINT
// or
player.stopHard(); // SIGKILL

Due to the nature of the spawned process, .stop() will not end immediately. However, .stopHard() is done via SIGKILL so it is not without fault.
