What I want to do is create a visual spectrum of a concurrently playing audio file like this
What I’ve gathered is that I need to read in the samples from the wav file and run a Fourier Transform on it to get a frequency spectrum.
I’ve done this with code from scratch but the spectrum I’m getting doesn’t look right and I would like to find a library to help. Android friendly is preferable but I’ll take anything at this point to get me going.
Does anyone know of a library that can do this and possibly something with a basic tutorial?
