How do I do operations on audio signal sampled data? For ex. I want to double the amplitude of audio data(multiply the data by 2)

Double to relative amplitude? Or double the pressure?

double the pressure

The back of my memory is saying that pressure is proportional to amplitude squared; if so then multiply by sqrt(2). I could easily be wrong on the relationship.
