Now we begin our journey into the actual maths of the Fourier Transform. Throughout the course, we'll be using sound to demonstrate one of the many uses of Fourier's theory, so in this lecture, we look at what sound actually is, how Fourier's theory applies to sound, and we even get to see a sound wave propagating through the air.
This is the fourth in this series of videos which take a new and visual look at the maths behind the magic of how the Fourier Transform works.
