MP3 and WMA files

MP3 (MPEG Audio LAYER 3) is a standard audio compression format.

Files can be compressed to approximately 1/10 of their original size using
MP3 compression.

WMA (Windows Media

TM

Audio) is a Microsoft audio compression format.

This format compresses audio data to a size smaller than that of the MP3

There is a limit to the MP3 and WMA file standards that can be used and to
the media/formats on which the files are recorded.
