I'm working in Audacity. What I need to do is to move the entire waveform graph up by a certain value. So for example all points with a value of 0 are supposed to become 10, every 10 is supposed to become 20, every -10 should become 0 and so on, for every point and every value. What I'm trying to do is the opposite of removing DC offset. I want to introduce an offset, and not just any offset. A specific value.
I'm aware that the graph will not be centered after the operation, that's exactly what I'm going for. (I need to misalign it by a very specific value, so it cancels out very specific portions of the other track. Reasons are unimportant.)
