I'll show you a typical application of FFT, a simple FFT analyzer. You can see what sort of frequencies exist in a music.
(1) See the movie of dsPIC FFT
  • 64-point FFT on a microcontroller
  • Shows spectrum from 0 to 4kHz on the LCD.
  • Anyway, see these (Youtube) movies.
(2) Source code of dsPIC FFT
  • C and header files of MPLAB+C30 projet.
  • Use wav files to inject test signals.
