Hi Joao, you need to find the peak amplitude, max(abs(x)), and divide all samples by that.

I tried adding all the values (=1.1 in this case), getting the inverse value and multiplying the list with that. Although the sum of the values is 1, the resulting wave isn't normalized to 1 the same way the "normalize 1" command would do it. So I imagine some higher math is required? Also, is the process the same if the wave components are harmonic or not (that is, multiples of the base frequency)?
