Hello. You can get the semisine (repeated parabola) by integrating a sawtooth function. Note the difference between the amplitude spectrum and the power spectrum.
sawtooth: 1, 1/2, 1/3, ... in amplitude but 1, 1/4, 1/9, ... in power, and described as -12 dB/oct.
semisine: 1, 1/4, 1/9, ... in amplitude but 1, 1/16, 1/81, ... in power, and described as -24 dB/oct.
Your additive synthesis is interesting. I too sometimes experiment with separating sawtooth waves into odd and even harmonics and shifting the frequencies of each.
440Hz sawtooth = 440Hz square + 880Hz sawtooth = 440Hz square + 880Hz square + 1760Hz sawtooth = ... --Dummy index (talk) 14:49, 12 April 2022 (UTC)
