How to specify the folder for wavwrite?

below are my code that i have written for wavwrite in the last line, the folder for the "x_Low_.wav" file is saved inside this folder.

          C:\Users\user\Documents\MATLAB

the question is, how can i change the placement of the "x_Low_.wav" file into another folder at other location that i want. Let say i want to put it on my desktop.

second question, can i rename the "x_Low_.wav" file into "seiska_filtered.wav" by itself? what is the proper function that i have to use?

[y,Fs,bits] = wavread('C:\Users\user\seiska.wav');
x = y(:,1);
clear y;
N = length(x);
time = [1:N].*(1/Fs);

fc = 2000;
fNorm = fc / ( Fs/2);
[b,a] = butter(10, fNorm, 'low');   
x_Low = filtfilt(b, a, x);          

sound(x_Low,Fs,bits);    
wavwrite(x_Low,Fs,bits,'x_Low_.wav');

hi,

you can put your file in directory you choose by the filename ,lets say you want save it the Desktop then :

filename='C:\Users\user\Desktop\x_Low.wav';
wavwrite(data,Fs,bits,filename);

to rename the file , i do not know if you can rename it with a command , just go to the directory and select the file , press F2 and put your new name ,

i tried your code. which my full code is

[y,Fs,bits] = wavread('C:\Users\user\seiska');
x = y(:,1);
clear y;
N = length(x);
time = [1:N].*(1/Fs);

fc = 2000;
fNorm = fc / ( Fs/2);
[b,a] = butter(10, fNorm, 'low');   
x_Low = filtfilt(b, a, x);          

sound(x_Low,Fs,bits);    
filename='C:\Users\user\Desktop\FYP2\x_Low.wav';
wavwrite(data,Fs,bits,filename);

however it gives error below

??? Undefined function or variable 'data'.

Error in ==> SaveFileToFolder at 14

wavwrite(data,Fs,bits,filename);

why is that?

hi Nadia, no i tried to explain generally saying that data is vector ,no it must work in your code try :

 wavwrite(x_low,Fs,bits,filename); % data  in general as vector

[Nadiah]

oh sorry. i forgot to rename it. thank you.

You can use uigetdir() to get the folder, then use fullfile() to build up the full filename. You can use copyfile() to rename a file.

[Youssef Khmou]

ok that is good way .

sound(unyil,Fs);

wavwrite(unyil,Fs,t,'unyil.wav');

Undefined function or variable 'wavwrite'.

why?

wavwrite() is an obsolete function that has been removed. It's been replaced by audiowrite().

Use audiowrite() instead.
