Section 7: Discrete Fourier Transform

This direct DFT MATLAB program is of academic interest only as MATLAB has an efficient fft procedure in its 'signal processing tool-box'. To illustrate its use, Table 4 is a MATLAB program which reads music from a 'wav' file, splits it up into 512 sample sections and performs a DFT analysis on each section. 7.4.
