First load data from file using e.g. importdata:

And then save it using wavwrite function:

i tried the foll lines it worked but i still dont understand the y in the syntax

load handel.mat

hfile='handel1.wav';

wavwrite(y, Fs, hfile);

where i handel.mat was an existing file.

That depends totally on the format of the TXT file. Step 1 is to read it into MATLAB and step 2 to maybe bring it into a format that is easy to export into WAV, which maybe fairly easy, see the doc for WAVWRITE:

Write WAVE (.wav) sound file 
Syntax
wavwrite(y,filename)
wavwrite(y,Fs,filename)
wavwrite(y,Fs,N,filename)

For reading the TXT file, I ssuggest starting it interactively:

File -> Import Data

Make sure you click on "Genererate MATLAB Code" in the Import Wizard. That will create reusable code and you don't have to think a lot about learning syntax of the many import commands.

hello ,

I tried using the import wizard to import the data into the workspace which worked. But in the syntax of wavwrite -

Write WAVE (.wav) sound file

Syntax

wavwrite(y,filename)

wavwrite(y,Fs,filename)

wavwrite(y,Fs,N,filename)

y is supposed to be a variable who's value is stored into the file 'filename'. I could'nt make out the connection between the variable 'y' and the data which is imported into the workspace . I'd be glad if you could help me out wit this .
