Fourier sine transform

A Fourier Sine Transform (FST) is a way of taking a complex signal and breaking it down into its basic components. It allows us to see how the signal is made up of different frequencies and how they combine to create the original signal. This can be useful when we want to see how something sounds in different ways, or if we want to identify the individual components of a signal. FSTs help us understand how sound works and can be used to analyze audio signals.
