Reading and saving wave files as .txt

Question

I am a highschool senior working on a musical analysis problem. I am afraid my Java isn't all that great. The nitty-gritty is I need a squential representation of the ampiltudes of a sound file( .wav of course) at the frequency at which is was recorded. If I am not mistaken the advantage of the wave format is that it is just that a list of integers corresponding to the ampiltude of the sound file at the recording frequency. So my job is read the array of bytes in the sound file and write them to a .txt file so that I can run other programs which I have already gotten.
I am currently trying to work with the Javax.sound.sampled API.
My code sorta goes like this:
public class analyse
public analyse()
AudioInputStream stream = AudioSystem.getAudioInputStream(new File("audiofile"));
DataLine.Info info = new DataLine.Info(Clip.class, stream.getFormat(), ((int)stream.getFrameLength()*format.getFrameSize()));
Clip clip = (Clip) AudioSystem.getLine(info);
WriteArray();
readArray();
line.drain().stop();
public writeArray() {
int numRead = 0;
byte[] buf = new byte[line.getBufferSize()];
while ((numRead = stream.read(buf, 0, buf.length)) >= 0) {
int offset = 0;
while (offset < numRead) {
offset += line.write(buf, offset, numRead-offset);
I had a friend suggest something like that and That wa just the bare bones of the program. readArray() would of course take the array and, using an iterator, write it to a text file.
However, I've also come across this code while looking thru the API
AudioInputStream stream = AudioSystem.getAudioInputStream(new File("audiofile"));
stream.read(byte[] b, int 0, int stream.frameLength()*stream.frameSize());
this I actually understand better, but I cannot get it to work.
If anyone could help me with this, I would sorely appreciate it.

Do you have QuickTime Pro? What "audio file" types are you referring to - MP3, WAV?
