converting 16bit int to 32bit float

Hello everyone

I know this topic is kindof old, but I've been trying to do the exact same thing with a java library I found and got stuck in the byte to float conversion. I've never worked with bytes before, my experience with coding is mostly trough web...

Volker's description in the first post describes raughly the steps to follow, and I get the big picture, but when trying to implement it the confusion comes.

The original code is part of an ogg decoding library ( by Tor-Einar Jarnbjo ). This belongs to a class that converts the ogg data into pcm and saves to a wav file, so I'm trying to get the transformed bytes and pass them to the mxj object output.
This is the code that gets the converted bytes and saves them to the file:
    try {
// read pcm data from the vorbis channel and
// write the data to the wav file

while(true) {
int read=vs.readPcm(buffer, 0, buffer.length);
// fuffer size here = 65536 and vs is a VorbisStream object
//returning the amount of bytes written to the buffer

for(int i=0; i
    // swap from big endian to little endian
byte tB=buffer[i];
buffer[i]=buffer[i+1];
buffer[i+1]=tB;
}
outFile.write(buffer, 0, read);
len+=read;
}
}
catch(EndOfOggStreamException e) {
// not really an error, but we've
// reached the end of the vorbis stream
// and so exit the loop
}

So if I understand correctly...the bytes we are writing to the buffer (65536) are 16 but pcm data, which means that if I take the buffer where we are writing it to a file, that's what it will contain, is this the byte[] data that I should wrap into a byteBuffer in order to call its getShort?
Should I take all the data in the buffer at once and get its short value to convert afterwards?
Should I put this code this inside the perform loop in my mxj object?

I know it's a lot of questions, and that's because I'm slightly confused with this, so any direction in what should I be looking into or understanding better would be very much appreciated.

Thanks in advance
