The rate of sampling can be used to convert these two durations (diss-length and fft-length) into a number of samples. Although many fast Fourier transform algorithms can transform data of any number of samples, the fastest execution occurs for lengths that are whole-number powers of two. It is recommended to round the number of samples up to the next power of two.
