A waveform audio file, also known as a wave file, or simply .wav after its extension, is a common type of sound file. Microsoft and IBM introduced the wav file in 1991 for use on the Microsoft Windows 3.1 operation system (OS). Long before digital audio became a staple, computer users were exposed to the wav file as an embedded sound file that played a chime-like sound at boot up of the Windows operating system.

The wav file had two very big things going for it when introduced. Firstly, it could digitize sounds 100% faithful to the original source because it is a lossless format. “Lossless” means that the wav file format does not compromise audio quality even when it holds compressed data. Secondly, the wav file is very easy to edit and manipulate with software. Luckily for audiophiles, free wav file editing software has been available nearly as long as wav files themselves.

While the wav file format was ideal for sound effects, it had a drawback when it came to music files. One four-minute song could easily consume over 35 megabytes (MB) of space when saved as a wav file. Though the cost of hard drives dropped over the years, the wav file format was still too large for portable players with limited flash memory, which would become ubiquitous by the new millennium. Additionally, wav files were not the most practical format to transfer online, especially over slow dial-up connections.

Today the wav file format is still widely used to archive music files in a lossless format where space is not an issue. Some CD and DVD players can also read wav files copied directly to a compact disk. More often, software that burns the files to CD will convert them in the process to the Compact Disk Audio (.cda) format, making the audio CD compatible with all players.

If you want to convert your WAV files to MP3, Windows Media Player is a good program to help you finish it. The following instructions will guide you through all these steps.

Step 1

To import your CD as a WAV, launch Windows Media Player (WMP), click Tools, then select Options. Click the Rip toolbar and select WAV as your rip format setting. Once you insert your CD, simply rip your files to WMP.

Step 2

Now, with that album ripped, start up the Switch program and get, well, a blank window:

Click on Add Folder and you can select the newly ripped CD by looking in My Documents\My Music:

Step 3

The last step, one that's not obvious when you first start working with Switch, is to pick the output format of your choice, as shown here:

You can see the program supports a wide range of options. Choose .mp3.

With the audio input files selected, the output format selected, and the destination disk specified, all that's left to do is select all the files to convert and click on the " Convert button on the top right. You'll get a progress window like this:

When it indicates that the conversion is complete, and you now have MP3 audio files from your WMA format files.

Short for Waveform Audio File Format, WAV is a widely used audio file type originally developed for use on PCs. Now compatible with Macintosh and Linux operating systems as well, WAV most commonly stores audio data in an uncompressed manner that ensures maximum quality. All modern audio players support the WAV format, including the popular Winamp, Windows Media Player and Apple QuickTime applications. All three are available for the PC and can be downloaded and installed at no cost.
