Hi
I am new to study DSP, and I would like to ask the following questions:
I have a test wav file, i use wavread to read the file as well as getting its sampling frequency, however I don't know how to plot the wav in FFT, the annoying thing is the frequency axis, I already know the sampling frequency is 8kHz, but I have no idea how can I plot the magnitude spectrum against its frequency.
Hope someone can explain to me the steps.
Many thanks
