Write sinusoidal mathematical equations in MATLAB to play your favorite song Solution Fs = 1000; %# Samples per second toneFreq = 50; %# Tone frequency, in Hertz nSeconds = 2; %# Duration of the sound y = sin(linspace(0, nSeconds*toneFreq*2*pi, round(nSeconds*Fs))); or sound(y,FS); %# play sound at sampling rate or soundsc(y,Fs); or wavread() sound() soundsc() flipud() wavwrite().
