What Method can be used in DR java for sound assuming the clip was not centered on neutral point zero but instead over. The wave should have plenty of room to be amplified because it has shifted. multiplying by any significant amount would almost immediately trigger clipping. So, what's the solution? To amplify and shift the sample values.

1) Method to find the highest and lowest value?

2)method to calculate intermediate values? (span between highest and lowest) ?

3)You'll need a second pass to do the shifting and amplifying (From a math point of view, It is easier to treat it as shifting then amplifying).

the program should calculate and normalize any WAV file.
