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.
