The Formula: Beat Frequency = Frequency 1 - Frequency 2

By "panning" (directing the sound) one frequency to your left ear, and then panning another frequency to the right ear, we can modulate certain brainwave activity (assuming you're wearing headphones in the first place). In other words, your brain will distinguish the different frequencies in each ear and will process a beat of its own that matches the difference between the two frequencies.

Below we have some examples of binaural beats. The shapes you see are shapes of the binaural beats audio wave form. This is how it looks on a tool called a goniometer. In music production, a goniometer is a display that shows the relationship between the phase of two or more signals. In this case, the two frequencies making the binaural beat. We use these beat frequencies in many of our tracks at low volumes.
