My final Nature of Code project is creating the effect of 3D audio with only two speakers. The process to create the effect of 3D audio is to invert the left channel. Next, is to reduce the amplitude of the left channel and feed into the right channel. This process is done to the right channel but vice versa. Next is to add a delay to each the left and right channel. The last step is to mix the processed audio back into the original audio track. The effect is a binaural 3D sound field.
Here is a demonstration of the 3D effect – 3D Sample
