how can i play sounds in specific order with specific durations

i need to let matlab play the happy birthday song. i already downloaded all the notes as wav files and i also put them in order in a list with the order of the duration.

duration=[0.5, 0.5, 1, 1, 1, 2, 0.5, 0.5, 1, 1, 1, 2, 0.5, 0.5, 1, 1, 1, 1, 3, 0.5, 0.5, 1, 1, 1, 2];

song=[si,si,do,si,mi,re,si,si,do,si,fa,mi,si,si,si,sol,mi,re,do,la,la,sol,mi,fa];

for exemple i need to play the note (si) first with a duration of (0.5 sec).

can anyone help?

Use a forcycle to run through all the notes with the appropriate durations using audioread. Also adjust each sound vector in dependence on the duration. See the idea below:

for i = 1:length(song)

% Load the note

[y, fs] = audioread('yourNote.wav');

% Example of y2 for halft the duration (0.5)

n = length(y);

y2 = y(1:fix(n*0.5), :);

% Play it

soundsc(y2, fs);

end

but like this you put only one sound in audio read with one duration. band my for loop should switch from 7 sounds wav in the specific order(like presented in the list with a specific duration for it.

[Giovanni Azar]

the duration should change each time according to the note that is playing from the list

The code was just a clue to lead you on. In that loop, you have to load the specific note in each iteration and adjust its playing duration. It's playing with the indexes. You already have an example for 0.5.
