Also, implementing a phase control for each harmonic would also be interesting for visualization.
Finally, why not add a wavetable synth to allow you to hear the resulting waveform?
Nice visualization! A few improvement suggestions -- I noticed that it is easy to clip the 'master' output, a 'master fader' to control its output (or a checkbox to rescale visualization based on maximum value). Also, implementing a phase control for each harmonic would also be interesting for visualization. Finally, why not add a wavetable synth to allow you to hear the resulting waveform?
This is really cool. I used to do a lot of overtone ("harmonic") throat singing and playing with this tool reminded me of those days. For anyone curious, vowels are mostly just how we perceive different harmonic distributions. Put differently, harmonics are the basis of what it means to pronounce a different vowel. The human voice is basically just a harmonic chord, with different distributions of the 2nd, 3rd, 4th,…
Lots of different notes present. Perfect 5th, major 2nd, major 3rd, major 7th are all found in the harmonic series. In addition there's some beautiful non-piano intervals, notably the 7th harmonic (slightly flat minor 7th) and the 11th harmonic (flat tri-tone)

Yes phase information is really important. Try this: 1. Fourier Transform an Image 2. Set all magnitues the the spectrum to 1.0, but do not change the phase 3. Inverse Transform and look at the result 4. Now try the same, but this time keep the maginutes unchanged but change all phases to 0° Spoiler: When changing all amplitudes the image is still regocognizable, when changing all phases, it is not. See example: [1]…
Phase information is important, but as far as I understand it, it is not important in audio: our ears are insensitive to phase. (Phase is important when combining different sinuses of the same frequency, because the sum of those will be different depending on their relative phase, but that's a different matter and not relevant here.) Changing the phases of the different frequencies will result in a waveform that look…

That reminds me, I saw a video recently of a choir practice where they sang "brighter" and "darker" based on the conductor's hand position. It was fascinating how the singers could control the brightness of their voice while holding the same note and frequency. When they went bright, it sounded closer to "eee" or "iii". When they went dark, it sounded like "uuu" and "ooo". From that, I learned that the lyrics of a so…
All it might need is the ability to manually enter the base frequency yourself or do an automatic sweep. But I could probably bodge that into the source myself.
Lovely!
