我如何用声音读取信号（）在Matlab中 [英] How I read a signal with sound() In Matlab

问题描述

嗨



我有两个信号首先是输入信号，其他是噪声信号我混合了两个信号并得到了一个信号，现在我想用声音播放这个信号（）函数，我需要它的频率，我怎样才能获得混合信号的最后一个信号的频率？



作为更多信息，我的代码就像下面：



[mainsigal，fs] = wavread（'mainsignal.wav'）;

[noisesignal，fs1] = wavread（' noisesignal.wav'）;％交通信号

s =主信号（：，1）;

n = noisesignal（：，1）;

l_s =长度;

，I = 1：l_s

h（I）= s（I）+ n（I）;

结束

声音（h，?????）;

现在我需要为h信号计算fs。









谢谢

hi

I have two signals first is input signal and others is noise signal I mixed two signals and got a signal, now I want play this signal with sound() function and I need frequency of it to play, how can I get the frequency of last signal that is a mixed signal?

as more information my code is like below:

[mainsigal, fs]=wavread('mainsignal.wav');
[noisesignal, fs1]=wavread('noisesignal.wav');%traffic signal
s=mainsignal(:,1);
n=noisesignal(:,1);
l_s=length(s);
for I=1:l_s
h(I)=s(I)+n(I);
end
sound(h,?????);
now I need compute fs for h signal.




thanks

你只需要采样原始信号的频率。

You just need the sampling frequency of the original signal.
