Dear Mehdi Ir: If you are a computer software student, learning MATLAB is a valuable task for you. It is very likely that your professor thought, that this projects helps you to learn.

Reading the Getting Started sections of the documentation is a good point to start from. Afterwards write the solution as far as possible and ask specific questions, when problems occur.

It would be counterproductive to post a solution here, because it would impede your learning.

BTW, "Emergency" is a bad subject. 1. it does not contain any useful information, 2. your problem is not an "emergency" and 3. the readers of this forum have read such "urgent" and "HELP!!!" subjects too often and they are bored by these exaggerations.

I like the questions with emergency, urgent and help as subjects. It makes me want to see how ridiculous the question is. It decreases the quality of my answer. +1 for your answer though.

I was 15 at that time, first times at a disco, first emergencies with grrls.

My parents told me when I was able to speak: "Never shout "help" if it is not _urgent_. _Urgent_ means: The sox your are wearing are burning and severe harm is imminent. If you do not wear the sox currently, it is not _urgent_, such that there is enough time to shout <<my sox are burning in the cupboard>> instead of <<help>>."

The first step is to read your file into MATLAB

doc fread

The next step is to write the data you read in to a wav file

doc wavwrite
