- WAV files have been in existence for almost 15 years, and are certainly the most reliable of the various audio formats. Since they are a native Windows format, all standard players, even on older machines, will support this file type. However, WAV files are a lot bigger than MP3 files and are not optimized for streaming, but are best for keeping your personal music collection in top-form on a personal computer.
- MP3 Files are a relatively new file type and are optimized for Web streaming and sharing. The MP3 files are at least 33 percent smaller, and achieve this petite size by "cutting" out the upper and lower 1 percent of sound. Generally, the sounds that are skimmed by the format are inaudible. MP3s are also very easy to use with personal audio devices, and are the most widely-used formats.
- Because the MP3 file only takes the middle range of audio pitches, some of the original audible integrity is lost. However, because 99 percent of the sounds come from this middle range, it is generally only noticeable to music enthusiasts or those with an especially trained ear.
