Is it possible to pre-generate an array from Spectrum Data?

Unity Engine

I’d like to implement something similar to. this in my game. While browsing through Unity’s documentation I noticed it says:
Returns a block of the currently playing source’s spectrum data

GetSpectrumData(samples: float[], channel: int, window: FFTWindow): void;
[B]Description[/B]
Returns a block of the currently playing source's spectrum data.

Would it be possible to pre-analyze a song’s spectrum data and then map the floats as an array to later iterate through a procedural mesh?

something along the lines of

foreach (float in spectrumdata)
{
terrain.setHeight(xPosition,yPosition, BaseHeight * spectrumdata[i]);
}

should get the job done but I’m developing for mobile so analyzing in real-time seems very expensive. Pre-analyzing would also allow me to smooth/average out the floats from the beginning to the end of the song, for a smoother experience.

Hello,

Have you found any solution to this? I have a game that uses getSpectrumData to set up lights, but in mobile (tested on android) seems to be very expensive.

thought of reducing sample size or pre calculate the array…
