As binaural beats are the consequence of two tones at specific frequencies I used an oscillator to make them. Based on my research into the relationship of binaurul beats and brain wave states, I created a left and right channel for each.

“When a sinusoidal pure tone of 250 Hz is presented to the left ear and a 256 Hz is simultaneously presented to the right ear, amplitude modulation with a frequency rate of 6 Hz is perceived by the brain (Figure 1)”(Jirakittayakorn, N., Wongsawat, Y. 2)

I found this quote and figure from Jirakittayakorn and Wongsawat to be the best explanation of binaural beats, it is now clear to me the process to create effective binaural beats with the ablitity to stimulate specific brain waves.

Using this logic I can create binaural beats, and by researching the frequency of certain brainwaves, I can encourage physiological effects such as enhanced mood, concentration, and creativity. Providing amplitude modulation with a frequency rate is no greater than 35 Hz as this is the highest perciavable difference to the human brain.

For my audio paper, I used the same carrier tone for all binaural beats, similar to the study mentioned within the text by Jirakittayakorn and Wongsawat. This scientific approach to variables within sound apposes my usual process of working, I tend to work based on intuition over logic
