I want to make a Microsoft media player clone. It will only play audio files more specifically mp3 and wav files. I want some help on how to make visualizations, like in the image I attached. I don't know much of allegro audio functions. Sorry for that. Thanks for help

I attached a zipfile that has source to something similar, meant to tune a guitar by finding the highest value of an FFT for a given note. It doesn't even compile anymore but it might give you some ideas.

They all watch too much MSNBC... they get ideas.

FFT is definitely what's used to make that. Read up on FFT.

ex_mixer_pp which comes with Allegro also could be useful.
