Hi William,


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

I'm not sure: if I use the amplitudes 1 0.5 0.25, the peak amplitude is 1, and the wave is clearly outside of the 1/-1 boundaries.

Basically what I'm trying to do is to find out what is the formula that does the "normalize" function.

Best,

Joao

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)?
