An MP3 (Moving Pictures Expert Group Audio Layer 3) is a file format of compressed digital audio. In a nutshell, MP3s are akin to the audio tracks on your CDs, only they take up much less space. For example, with an uncompressed CD file, each minute eats up 10MB (megabytes) of memory. With MP3s, each minute only uses 1 MB. The one-minute, one-megabyte rule is a good reference to use in the world of MP3s, especially when considering how much memory you will need.
