I use a free utility, FormatFactory, for converting many different file types, including converting .WAV audio files to .MP3.
When you record your songs, many pieces of recording software do not save natively as mp3 files. But even when they do, it is often not the most desirable format.
Typically, .WAV files are uncompressed and of higher quality than mp3 files. So when you want to burn a CD of your songs, save the file as a .WAV file. When you want to upload the file to the Internet, convert it to an mp3 file.
After converting it to mp3 file, you will want to “tag” that file as well. I will have another tutorial and utility for doing that.
For now, take a look at how to use FormatFactory to convert .WAV files to MP3.
