How to open .wav as .raw in python, or other languages?

First, I will list my process:

1. -Open .wav as .raw in Photoshop (with set px dimensions)
2. -Place a composition over the canvas
3. -export as .wav
4. -edit/alter the audio in Audition
5. -open back up in photoshop with the same set px dimension to see results

example: Piece:So, what I want to do is perform step 4 with a live feed of the effects happening to the image in a frame. This is how I assume I'll have to go about it:

1. Figure out the mathematics behind .wav and .raw files to be able to open .wav as .raw
2. Install an audio effect package and create an audio effects chain
3. Create on/off buttons or sliders for different fx
4. Create frame with specifc px dimensions to view changes to audio/image.

The goal here is to be able to have audience members interact with live pieces in an exhibition, showing the relationship between digital sound and image.

Any help about references, where to start, etc. would be much appreciated!
