## MediaDecoder.java
/* MediaDecoder

   Author: Andrew Stubbs (based on some examples from the docs)

   This class opens a file, reads the first audio channel it finds, and returns raw audio data.

   Usage:
      MediaDecoder decoder = new MediaDecoder("myfile.m4a");
      short[] data;
      while ((data = decoder.readShortData()) != null) {
