Midterm project

There are six buttons in my screen which stand for six kind of music.

(1)   Normal.ver [00:00]←Start time

I make a song which stand for a people’s whole lifetime like a story. The song consists of twelve different chants.

Here is the order:

Heartbeat(A person was born.)→Infant’babble→Little star(A song people usually sing for baby.) →Bell ring(He become a teenager,and go to school.) →People cheer(He graduate from school.) →Train sound(He leave his hometown to find work.) →Kiss sound(He meet a person he like.) →Wedding song(They get married.) →Baby cry(They have a chid.) →Happy song(He have a great late adulthood) →Electrocardiogram sound(He die.) →I will remember you(People come to cherish him.)

(2)Cartoon.ver [02:35] ←Start time

I changed the amplitude of every note ,include the sampling frequency,in order to make it sound like a cartoon.

(3)Fast.ver [05:05] ←Start time

I turn b=audioplayer(y,fs) into b=audioplayer(y, 3*fs) to change the speed of the audio signal ,and make the song sounds faster.

(4)Slow.ver [06:06] ←Start time

I turn b=audioplayer(y,fs) into b=audioplayer(y, 2/3*fs) to change the speed of the audio signal ,and make the song sounds slower.

(5)Loud.ver [09:46] ←Start time

I turn b=audioplayer(y,fs) into b=audioplayer(20*y,fs) to change the amplitude of the audio signal ,and make the song sounds louder.

(6)Whisper.ver [12:18] ←Start time

I turn b=audioplayer(y,fs) into b=audioplayer(1/20*y,fs) to change the amplitude of the audio signal ,and make the song sounds like whisper.

(7)Close

Click it can end the program.

The following is my code:

function varargout = untitled(varargin)

% UNTITLED MATLAB code for untitled.fig

%      UNTITLED, by itself, creates a new UNTITLED or raises the existing

%      singleton*.

%      H = UNTITLED returns the handle to a new UNTITLED or the handle to

%      the existing singleton*.

%      UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in UNTITLED.M with the given input arguments.

%      UNTITLED('Property','Value',...) creates a new UNTITLED or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before untitled_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to untitled_OpeningFcn via varargin.

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".
