LÖVE

There was no school to day and to kill some time, I made a waveform visualizer (it also plays the corresponding tone). It uses lines and a table of y positions. I was going to try and make one out of GLSL, but GLSL confuses me deeply .

This makes a cool song. I like it.

Neat little demo!

I noticed you draw all the lines individually, in a for loop. It works well and doesn't really matter much, but you might want to know that love.graphics.line can take a table as arguments as well. So if you'd save the y AND the x values into the wave table, you could simply call:
love.graphics.line(wave).

But it doesn't really matter...

The problem with using a table of both x and y values is the x value will always stay the same relative to the y value. The for loop uses the iterator for the x while removing the first Y value. When the 1st Y value is removed, all the remaining values shift down one (removed<-1st <- 2nd <- 3rd...). By doing this, the wave looks like it is moving.

I did fix two things though. The first point is know drawn in the right position and the height and width are corrected. need to stop coding things at 2 a.m...

Uh, you're right. My bad, sorry, I didn't think it through...
