Matlab code, lab report and a power point presentation

I need the code for the (Car Horn in The Tone of F). You can find the description in the attachments. Please use the (test_yes_no_ , test_yes_no_for_instructor and yes_no) files to find the code parts for wavread (AudioRead in the updated version) and FFT. The other two files ( car_horn_1 and car_horn_2) are used as in the description. Please explain everything in details in the lab report.
