wave to raw conversion

hey --
i needed a quick app to take wave files and make them into raw data files i could read in c++. i am using these files for granular synthesis, and it is much more straightforward to do it in java/processing then to go through the trouble of loading files in in the c++ framework when i don't want to do it in real time anyway. this is what rules about having this type of prototyping, etc. environment around -- i tooled for hours in c++ trying to load in a dumb wave file with a framework that wasn't compatible with the one i had already been programming in. processing was the first thing i thought of when i considered an outside tool to generate the raw files for me. i may write a small "header" for these files which contains the length, etc., but for now this is good enough.

Code:
BSound samp;
void setup()
{
samp = loadSound("dre.wav");
byte[] samps = new byte[samp.length];
println(samp.length);
for (int i=0; i<samp.length; i++) {
byte a;
a = (byte)((samp.samples[i])+127);
samps[i] = a;
}
saveBytes("numbers.txt", samps);
}
void loop() {
repeat(samp);
}
