is possible to make sound spectrum thing like this (in real-time rendering)?

You might be able to do it with a fourier transform.

Luau FFT About Luau FFT is a module which can be used to perform discrete Fourier transforms on Roblox. Features Bundled with an easy-to-use complex number module Calculate fast Fourier transforms Calculate discrete Fourier transforms What is a Fourier transform? In simple terms, a Fourier transform can be used to find out the intensity of sine waves of various frequencies that can be used to construct virtually any function. A common use for this is to calculate the frequency spectrum …

Edit:
@OP What you might be interested in is something called a spectrogram, which can be created using the resource above.

its a bit different, but I will try to experiment with it.

For real-time purposes, using AudioAnalyzer:GetSpectrum and somehow visualizing the spectrum on an EditableImage might be your best bet. My FFT library that @x86_architecture linked can work in theory, but it can’t get a full 20-20,000 Hz spectrum in real time because you won’t be able to sample it at the ~40,000 Hz required to get the full audible spectrum.
