     double max = Double.MIN_VALUE;

     do

        framesRead = wavFile.readFrames(buffer, 100);

        // Loop through frames and look for minimum and maximum value
        for (int s=0 ; s<framesRead * numChannels ; s++)
        {

You need to download the java files from HERE and add them to the same package as your code.

then change this line:

WavFile wavFile = WavFile.openWavFile(new File(args[0]));

to:

WavFile wavFile = WavFile.openWavFile(new File("D:/p.wav"));
