HW1, ECE301, Prof. Boutin

In this homework assignment, we were asked to write a Matlab code to play the "Hail Purdue" song with different speeds and pitch.

%Jayanth Athreya
%Home Work 1.1  Hail Purdue Song
%Not very sure. Thought it sounds something like it
 steps = 0.00025;   % Initialising the steps.I think it is very lengthy
 t=0:steps:0.5;     % Setting the interval
soundA = sin(2*pi*330*t);  %First sound
t=0:steps:0.6;             %Break between the previous and the next sound  
soundB = sin(2*pi*338*t);  %Second sound
soundC = sin(2*pi*390*t);  %Third sound
soundD = sin(2*pi*420*t);  %fourth sound
soundE = sin(2*pi*490*t);  %fifth sound
t=0:steps:0.53;            %break 
soundE = sin(2*pi*490*t);  %Repitition of the fifth sound
t=0:steps:0.5;             %break
soundF = sin(2*pi*500*t);  %Ending sound
HailP = [soundA soundB soundC soundD soundE soundF];  %Programming statement
sound(HailP,1/steps);                                 %sound command

sound(HailP,1/steps*2);   %To get the song to play at two times the actual speed.
