Summary:
This project is a real time pitch recognition tuner with the LPCXpresso54608 micro-controller. Our algorithm relies heavily on Fast Fourier Transforms and harmonic power spectrum analysis. An electric guitar or bass will be input through an auxiliary cord. The LCD screen on the micro-controller will output the frequency response, as well as lines indicating the closest ideal frequency and actual frequency. The value of the actual and ideal frequency are displayed, along with an indicator for the nearest pitch to the note played.
