The synthesis algorithm for Wigout

Let's suppose you have the following waveform:

In this waveform, there are four elements: e1, e2, e3, and e4. These four elements are iterated (repeated) four times. At each iteration, each element remains the same: neither its amplitude nor its duration changes.

Now let's suppose that on every iteration, each element got progressively higher (or lower), and got longer (or shorter). Then the four iterations might look like this:

Elements e1 and e2 keep getting higher, and elements e3 and e4 keep getting lower. All four elements get longer.

Acoustically, this means that the sound will get louder (since the maximum displacement of the waveform is increasing) and lower in pitch (since the overall duration of the waveform is increasing).
