delay

public void delay()

readAUFile

public void readAUFile(java.lang.String fileName)

Open the fileName and read in the data as if it were u-law encoded. Then turn it into linear PCM data.

main

public static void main(java.lang.String[] args)

readData

public static byte[] readData(java.io.InputStream is)
                       throws java.io.IOException

Reads in all the data affineTransform once, from any inputstream. Remember to close the InputStream when you are done.

Returns:

Array of data

Throws:

java.io.IOException
