Multiple conversion mp3 to wav ?

Hi, I'd like to know how can I convert many mp3 songs into wav ones taken from a path in my computer. (here there's also a mono conversion)

The simple code for a single conversion is:

[audio,fs,nbits] = mp3read('BrainDamage.mp3');

wavwrite(audio,fs, nbits,'BrainDamage.wav');

[audioMono,fs,nbits] = wavread('BrainDamage.wav');

Mono = (audioMono(:,1)+audioMono(:,2))/2;

wavwrite(Mono,fs, nbits, 'BrainDamageMONO.wav');

I know that with:

songs =dir('C:\myPath\*.mp3');

for ii=1:size(songs,1)
...

i can select all the mp3 files in my folder but how can I change their extension together?

thank you for your help

sorry but I can't find the part where it's explained the multiple type-conversion. It only says how to select and import many file of the extension ".jpg".

I'd like to know how to convert many files from mp3 into wav (mono) with a loop for. How can i keep the name of the file, apply the conversion and give it to the new file with extension ".wav" ? thanks
