《MATLAB ADVANCE》用Matlab生成音乐

1.采样率：
采样频率是指将模拟声音波形进行数字化时,每秒钟抽取声波幅度样本的次数。
在Matlab中，默认采样率是8192，Matlab的采样率的范围是1000Hz ~ 384000Hz.
2.写如下程序：

clc;clear;
Fs = 8192; %设置Matlab默认采样率。
x = linspace(0,2*pi,Fs); %用采样率对横坐标取点。
y = sin(x);
plot(x,y); %画出声波图。
sound(y,Fs); %播放声音。

发现此时无任何效果，是因为声波只有一个周期，一秒钟的时间内只完成了一次震动，频率为1Hz，是次声波，人耳听不到。因此需要对正弦函数的频率做一些变化。比如将频率设置成440Hz：

clc;clear;
Fs = 8192; %设置Matlab默认采样率。
x = linspace(0,2*pi,Fs); %用采样率对横坐标取点。
y = sin(400*x);
plot(x,y); %画出声波图。
sound(y,Fs); %播放声音。

此时可以听到电脑按照440Hz频率发出“嘟”的声音。
3.比较不同采样率对声音的影响：

clc;clear;
Fs1 = 8192;
Fs2 = 20000;
x1 = linspace(0,2*pi,Fs1);
x2 = linspace(0,2*pi,Fs2);
y1 = sin(440*x1);
y2 = sin(400*x2);
sound(y1,Fs1); 
sound(y2,Fs2);

发现两者的声音没有任何差别，说明声音的采样率对音色没有影响，只有频率才对声音的音色有影响。
4.十二平均律：

以小三度?为do，一个八度音为：

编写程序，播放整个八度音：

clc;clear;
Fs = 8192;
x = linspace(0,2*pi,Fs);
fullKey = [523 587 659 698 783 880 988 1047]; %存储全音频率。
semiKey = [555 623 741 832 938]; %存储半音频率。
soundTest = [];
soundTest = [soundTest,sin(fullKey(1)*x)];
soundTest = [soundTest,sin(semiKey(1)*x)];
soundTest = [soundTest,sin(fullKey(2)*x)];
soundTest = [soundTest,sin(semiKey(2)*x)];
soundTest = [soundTest,sin(fullKey(3)*x)];
soundTest = [soundTest,sin(fullKey(4)*x)];
soundTest = [soundTest,sin(semiKey(3)*x)];
soundTest = [soundTest,sin(fullKey(5)*x)];
soundTest = [soundTest,sin(semiKey(4)*x)];
soundTest = [soundTest,sin(fullKey(6)*x)];
soundTest = [soundTest,sin(semiKey(5)*x)];
soundTest = [soundTest,sin(fullKey(7)*x)];
soundTest = [soundTest,sin(fullKey(8)*x)];
sound(soundTest,Fs);

发现现在的声音是没有强弱之分的。
5.调整声音的强弱：
用以下函数叠加原理，可以进行声波强度渐弱处理：

clc;clear;
Fs = 8192;
x = linspace(0,2*pi,Fs);
fullKey = [523 587 659 698 783 880 988 1047]; %存储全音频率。
semiKey = [555 623 741 832 938]; %存储半音频率。
soundTest = [];
soundTest = [soundTest,sin(fullKey(1)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(semiKey(1)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(fullKey(2)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(semiKey(2)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(fullKey(3)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(fullKey(4)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(semiKey(3)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(fullKey(5)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(semiKey(4)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(fullKey(6)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(semiKey(5)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(fullKey(7)*x).*(1-x/(2*pi))];
soundTest = [soundTest,sin(fullKey(8)*x).*(1-x/(2*pi))];
sound(soundTest,Fs);

现在听起来就有了减弱音效的效果。
声音渐强处理的原理也是一样的：

clc;clear;
Fs = 8192;
x = linspace(0,2*pi,Fs);
fullKey = [523 587 659 698 783 880 988 1047]; %存储全音频率。
semiKey = [555 623 741 832 938]; %存储半音频率。
soundTest = [];
soundTest = [soundTest,sin(fullKey(1)*x).*x/(2*pi)];
soundTest = [soundTest,sin(semiKey(1)*x).*x/(2*pi)];
soundTest = [soundTest,sin(fullKey(2)*x).*x/(2*pi)];
soundTest = [soundTest,sin(semiKey(2)*x).*x/(2*pi)];
soundTest = [soundTest,sin(fullKey(3)*x).*x/(2*pi)];
soundTest = [soundTest,sin(fullKey(4)*x).*x/(2*pi)];
soundTest = [soundTest,sin(semiKey(3)*x).*x/(2*pi)];
soundTest = [soundTest,sin(fullKey(5)*x).*x/(2*pi)];
soundTest = [soundTest,sin(semiKey(4)*x).*x/(2*pi)];
soundTest = [soundTest,sin(fullKey(6)*x).*x/(2*pi)];
soundTest = [soundTest,sin(semiKey(5)*x).*x/(2*pi)];
soundTest = [soundTest,sin(fullKey(7)*x).*x/(2*pi)];
soundTest = [soundTest,sin(fullKey(8)*x).*x/(2*pi)];
sound(soundTest,Fs);
plot(soundTest);

如果想要声音减弱或加强随时间变化更明显，可以用指数函数来叠加！
6.延长声音震动的时间：
写如下代码，感受x长度不同带来的声音的不同：

clc;clear;
Fs = 8192;
x1 = linspace(0,2*pi,Fs);
x2 = linspace(0,4*pi,Fs*2);
fullKey = [523 587 659 698 783 880 988 1047]; %存储全音频率。
y1 = sin(fullKey(1)*x1).*(1-x1/(2*pi));
y2 = sin(fullKey(1)*x2).*(1-x2/(4*pi));
sound(y1,Fs);
pause(1);
sound(y2,Fs); %声音采样率要设成一致。
subplot(1,2,1)
plot(y1);
subplot(1,2,2)
plot(y2);

7.创建一个简单的产生用户所需音调、强度(一般想要的都是减弱，所以以减弱为例)、延音大小(几分音符)的函数：

%半音：tone为输入两个音对应的数字的平均数。
%高八度：tone为输入的数字要乘以十。
%低八度：tone为输入的数字要除以十。
%两个高八度：tone为输入的数字乘以一百。
%两个低八度：tone为输入的数字除以100。
%rhythm代表几分音符，1代表全音符，0.25代表1/4音符，以此类推。
function y = note(tone,rhythm)
Fs = 8192;
fullKey = [131 147 165 174 196 220 246 261 293 329 349 392 440 494 523 587 659 698 784 880 987 1046 1174 1318 1396 1567 1759 1975 2092 2348 2636 2792 3134 3518 3949]; %存储三个八度的全音频率。
semiKey = [138 155 185 207 233 277 311 370 415 466 554 622 740 830 932 1108 1244 1479 1660 1864 2216 2488 2959 3321 3728]; %存储三个八度的半音频率。
x = linspace(0,2*pi*rhythm,floor(Fs*rhythm));

end
y = sin(tone*x).*(exp(-0.6*x));
end
