an audio file from my usb stick.
That is hard because you need a USB host shield and a whole heap of software to talk to it.
Use an SD card, it is much simpler. I would use an Adafruit wav shield as it has all the components you need. Other options include using a DFplayer board as that can handle MP3 files as well.

What ever you choose there will be example code that shows you how to program it.
