What mathematical function could be used to simulate this sound effect?

I have this sound effect which by the way if anyone could give me its name, I would really appreciate it. And after loading it into matlab/octave (don't worry this isn't a programming question) using the following commands:

[x, fs] = audioread("Path To File");
plot(length(x(:,1)),x)
sound(x,fs) % To hear the sound


I get the following: Could anyone tell me what mathematical function I could use to simulate this?

• So you have a recording of a sound, you don't know what it is called or how to model it, but you want to do some simulation with it? I'm not following this Commented Jan 24, 2021 at 19:35
• I think you should be clearer about what you mean when you ask how to simulate it. Do you wish to generate the same sound? a similar sound? If it is the same sound just take this one. If you want a similar sound you have to specify how similar. you can only define how similar if can define the sound. If you do not know how it is called or what it is, how can you generate something similar? Commented Jan 25, 2021 at 6:38
• @havakok I want to generate one as similar to this one as possible. I got it off free from the internet but I want to be able to know how to generate one as similar as possible. It's a mere curiosity. Commented Feb 18, 2021 at 13:26
• @daviddavid this is not a sound. this is a drawing of a function that could be a sound. It could also be any other signal. You do not know what is the sound, all you know is that you have it. Generating a sound could be a complex task involving understanding that sound's features which you don't. No one can help you if you don't know what you want to generate.

• @havakok I want to find a mathematical function that closely simulates the drawing of the sound. I do not plan on using regression of whatever sort or similar. I can then play the sound using the function using a similar version of the program mentioned above. I plan on recreating it synthetically not in real life Commented Feb 21, 2021 at 21:11
