14. Definition
WMA
Short for Windows Media Audio, WMA is Microsoft's digital music format. WMA is
probably the most widely used format, universally supported by almost every online
music service and digital music player (except Apple).
WMA comes in both a copy-protected and non-protected version.
MP3
Short for Moving Pictures Experts Group-1, Layer 3, MP3 is still used as general
terminology for any type of digital music file. In reality, MP3 is not the default format
for most online stores and digital music players. Most online stores automatically
convert MP3 files to their default format (WMA or AAC) before transferring the files
to a digital music player.
