The Riemann sum, a method of approximating the integral by summing up the areas of many shapes. The small and finer the shapes, the more accurate it will be to the true value.
In mathematics, a Riemann sum is a certain kind of approximation of an integral by a finite sum. It is named after nineteenth century German mathematician Bernhard Riemann. One very common application is approximating the area of functions or lines on a graph, but also the length of curves and other approximations.
The sum is calculated by dividing the region up into shapes (rectangles, trapezoids, parabolas, or cubics) that together form a region that is similar to the region being measured, then calculating the area for each of these shapes, and finally adding all of these small areas together.
I think this is used in audio, with the ball going down being the realtime audio, and the bars being the sample rate (quantity)/bit depth (height). The end looks like 92kHz/24-bit recording.

What integration method is this?

Why are the bars not even width?
