Hi! I am doing a research paper over this concept in my high school IB class and want to understand how I can create a patch using only 1 frequency and not 2 in order to create different patterns that correspond with different frequencies. Using this, I want to create a visual universal sound alphabet. Do you know any way I could do this? I have no experience with max and sadly don’t have time to learn it completely by when the paper is due. I saw your other comment that ties with making a ratio of M and N but can’t implement it into Max. Thank you so much for making this video. Anything helps! 😁
What you describe is very, very tricky - it would require you to model the actual physics that make the phenomenon possible. Maybe you can find a way to take a frequency and derive two numbers (or one ratio) from them?
love this, thank you for such a detailed explanation. i'm wondering how we could determine this ratio is between N and M? as typically our source would be either one frequency, a collection of frequencies/an audio source? (lets call this F). to determine N and M from F we could express this as N = F * R1 M = F * R2 where R1 and R2 are ratios of F, so we could rewrite your equation as force = (sin(pi*(f * R2)x) * sin(pi(f * R1)y)) + (sin(pi(f * R1)x) * sin(pi(f * R2)*y)) * v would it be correct in assuming (as a non mathematician) that R1 and R2 are integer values representing the order of the harmonics? where if R1 = 1 and R2 = 2, N would represent the fundamental frequency, and M would represent the second harmonic (which is twice the frequency of the fundamental) ?
This is definitely one way of doing it - you would get the R1 & R2, derive a ratio from them, and apply it to your sound generation process. I also applied this by working with harmonic intervals. Using a MIDI keyboard, slicing out the two simultaneous notes played, and getting their ratio as the basis for the N & M values.
Hey, im fairly new to this programm and im still learning. Excellent tutorial btw. I have a question, how can i connect my song to this project and make it vizualise my song?
There are a lot of ways you can turn audio signals into numbers, to be used as a frequency for the cymatics in this patch. Check out [peakamp~] for an example.
Hi thanks a lot for this tutorial, I tried to patch a midi keyboard however Im getting the same shapes and patterns throughout different keys from the piano keyboard regardless of how much force I am applying to press the keys. Is any how this can be solved ? Would be kind to provide the tutorial concerning this ? I am looking forward to hearing from you. thanks
For those of us who can understand formulaic expressions, it would be great to have a video explanation of how cymatic maths work. Thank you for your help 🎉
Absolutely! Check out the [mix] operator in [jit.gen] which will interpolate between two matrices. Try and see how you can change it from its position to a random place.
