An MP3 encoder is a program that allows you to convert wav-files into mp3 format. You can
compress the file size down to 10% of the original size, almost without reducing the quality
of the sound. In other words, a 40Mb wav-soundtrack would only be 4Mb if you convert it into MP3.
This is a great way to store soundtracks on your computer or a public server.
