Question

<p>I need to write a program that generates notes c-cleff. The function should output a vector of samples of a note at the specified sampling rate and for the specified duration. Typical duration value for a quarter note is 0.15 seconds and an acceptable sampling rate is 10,000 samples per second. The function should be called "mytone." i must write the main program that calls on mytone for notes in a song so that my program plays "Mary had a little lamb".

Explanation / Answer

I need to write a program that generates notes c-cleff. The function should output a vector of samples of a note at the specified sampling rate and for the specified duration. Typical duration value for a quarter note is 0.15 seconds and an acceptable sampling rate is 10,000 samples per second. The function should be called "mytone." i must write the main program that calls on mytone for notes in a song so that my program plays "Mary had a little lamb". BELOW IS WHAT I HAVE DONE SO FAR AND WHERE I AM STUCK.

This is the tone function that i have come up with.

function [x] = Tone (fo, tduration)

fs=5000;
ts=1/fs;
t=0:ts:tduration;
x=sin(2*pi*fo*t);

end

Now I need to call "mytone" function so i can play the notes, this is what i have so far but it is not working and i cant hear any sounds.

fs=8000
a = Tone(4000,.1)
x=[x a]

soundsc(x,fs)

my version goes as follows

% pure tones

clear

freqs = 5000;
duration = 0.1;

for i = 1:length(freqs)

sampleFreq = 44100;
dt = 1/sampleFreq;

t = [0:dt:duration];

s=sin(2*pi*freqs(i)*t);
sound(s,sampleFreq);
