Not exactly a Java.Sound.* problem...

Question

Hello folks! I am writing a piece of code that takes a .wav file, encoded with 16 bits/sample, and has to perform a "thersholding" operation in these samples. That is, that groups of samples that don't have enough mean energy, shall not be included in the new .wav file that will contain the thresholded sample (the whole process is a short of compression).
The problem is, that for some reason I haven't discovered yet, only half of the bytes of the original file are found in the final file! (But, the thresholding mechanism works well in these half samples :P)
Could you please check on my code? 15 javies for the one who gives me a solution! :)
Here goes my code
// 16bits/sample
// line 47 -> input .wav file
import java.io.*;
import javax.sound.sampled.*;
public class thresholding16 {
public thresholding16() {
try {
jbInit();
} catch (Exception ex) {
ex.printStackTrace();
AudioFormat audioFormat;
AudioInputStream audioInputStream;
//initial samples from File
byte buffer[] = new byte[10000000];
//thresholded samples ->to be written in a new File
byte newBuffer[] = new byte[10000000];
//the initial 2-byte samples will be represented as an integer (by merging the MSB,LSB of the sample)
int intArray[]=new int[5000000];
//mean energy of samples for every one of the 200000 groups of 25 samples
double energyArray[] = new double[200000];
public static void main(String args[]){

How do i merge all the XSL's..... can i use something
like a master XSL that calls the other 4 documenst
one after the other.
Something like <XSL:Import> or <XSL:Include>
You can import other stylesheets and use the templates they contain. You can also import one or more stylesheets and then optionally redefine any templates that they define.
<xsl:stylesheet      version="1.0"      
                                   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                                   xmlns:java="http://xml.apache.org/xslt/java" exclude-result-prefixes="java">
     <!-- import the core functionality -->
     <xsl:import href="../common/generic_csv.xslt"/>
Some other templating code...
</xsl:stylesheet>Is this what you are after?
