Our church's website has a multimedia page. We have some sermons posted for listening. It takes 2-4 min. to download to real player. These were created as a .WAV file and then stored on a audio host site. I was told that if they were .MP3 it would make the file smaller and shorten the download time. I converted a file from .WAV to .MP3 and the 50mb file became 72mb. So what is better? .MP3 or .WAV Here is the page.
