can mp3 music files be used webpage

.wav files are quite large. Is there a way - a plug in perhaps of using mp3 files in webpages instead of .wav files ?

thanks

 

do you mean to automatically play when your site is accessed?? that depends on your webspace provider and on your coding....give us some more info is it free hosting?? give us a link to the page you're talking about and i'll have a look at the code

 

just a standard webpage (provider 50 mb of webspace allowed)
I converted an mp3 file to a wav file and used frontpage as a web creator ( .wav used as background music).
However the .wav file is 11 tiems as large as the mp3 file (40 mb). It is a bit large to upload/play and I thought if it was possible to use the original mp3 file in the webpage rather than the .wav file it would speed things up.
