Sound may be modeled as sinusoidal functions. Compare the relative frequency and wavelength of musical notes. Use 330m/s as the speed of sound and the following frequencies for the musical scale Note C D E F G A B C
Frequency 264 297 330 352 396 440 495 528
Frequency Difference
Wavelength
Frequency difference C 33 D-33 E-22 F-44 A=55 B-33
wavelength 1.25 1.11 93 83 75 62
Generate all the musical notes in problem 2 with the same amplitudes and phases. Change the N = 10000.
Question:
1. Put all the musical notes in one vector and use function sound(y) to play the sound. Include your code.
2. Play the sound [E, E,F, G,G, F,E, D,C, C,D, E,E, D,D].
