求助 希望帮忙啊xiexiexiexie
界面为右图 程序代码如下 怎么运行不了啊 求助function playsound(soundtype,frequency,amp,phase)
Fs=41000;%设置采样频率
x=;
switch soundtype=input_1
case 1 %正弦波
y=amp*sin(2*pi*x*frequency+phase);
case 2 %方波
y=amp*sign(sin(2*pi*x*frequency+phase));
case 3 %三角波
y=amp*sawtooth(2*pi*x*frequency+phase,0.5);
otherwise
errordlg('Illegal wave type','Choose errer');
end
plot(x,y);%显示波形
axis();
wavplay(y,Fs,'async'); %播放声音，使用async(异步)模式可以实现发声的混迭
