How can I get the spectrum out of a 2048 float32Array

I've looked at your documentation and couldn't find a real situation example where the array is filled with data.So my question is how can I get the Spectrum values of a float32array filled with audio values.

Thanks in advance

Start with the project documentation and the FFT API entry point to find how input Float32Array audio samples are passed and how output values are read. Add a real 2048-sample audio example showing how to obtain spectrum values, and verify that the documented example matches the public API.
