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

Hello list,
I was curious about the following math issue: when defining a waveform using "sinesum 0.8 0.2 0.1", what would be the formula to normalize the wave to 1? 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)?
Best,
