A MATLAB script reads the .wav file

A MATLAB script reads the .wav file and generates a DTI plot by ignoring the
synchronization pulses (Left channel) and parsing the video data (right channel) into 100 ms blocks then computing the Fourier transform.
The log magnitude of the result is plotted as a DTI plot, where, for example more than a dozen vehicles traveling at a velocity of up to about 13 m/s are observed (Fig.7)
