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);

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

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.

nol = [zeros(size(t))];
unyil = [b,nol,a,nol,g,nol,a,nol,b,nol,a,nol,a,nol,nol,nol,b,nol,a,nol,g,nol,e,nol,g,nol,e,nol,e];
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 It's been replaced by audiowrite().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.
