(Vertical leaf conversion is widely used in communication, optics and geography. The research based on PC platform is now appropriately sophisticated, with more tools and libraries available (such as MATLAB and FFTW source library). However, it is difficult to find relevant libraries and analysis tools on embedded systems, especially on Android systems. However, Fourier transform has an indispensable effect in the fields of audio analysis and game development, so it can be used in embedded systems)
