How music works, using Ruby

That strange phenomenon where air molecules bounce against each other in a way that somehow comforts you, makes you cry, or makes you dance all night: music.

Sound engineers have found many ways of making music sound good when played from a record. Some of their methods have become industry staples used on every recording released today.

Let's look at what they do and reproduce some of their methods in Ruby!
