ActionScript 3.0 :: MP3 Loading Into Movie With Low Volume

I have this rather large movie file that I'm working on and unfortunately the mp3s that I'm loading into the movie are all at a very low volume. So I'm using the below code to raise my volume but I'm anticipating on having about 25 instances and I need to create, I believe, either an array or a class that "calls" the idea/objective behind code below.

Code:
var channel:SoundChannel = new SoundChannel();
var volumeControl:SoundTransform = new SoundTransform();
volumeControl.volume = 4;
var audioURL:URLRequest = new URLRequest("Scary Stories To Tell In The Dark/01 The Big Toe George S. Irving.mp3");
var bigToe:Sound = new Sound(audioURL);
channel = bigToe.play();
channel.soundTransform = volumeControl;
