Frequently asked questions
General questions
What is MP3?
MPEG-1 Audio Layer 3, one of most
popular audio formats. It compresses
standard audio tracks into much smaller
sizes without significantly compromising
sound quality. Since the MP3 file format
has no mechanism for copyright
protection, it is not widely used by
commercial music data distribution sites.
What is WMA?
Windows Media Audio is an audio format
developed by Microsoft Corporation in
order to distribute CD-quality music even
via low-speed communication lines such
as ISDN. WMA employs a more efficient
compression method than MP3, and has
the advantage of reducing the bit rate with
the least loss of sound quality (80 kbps
encoding results in almost the same sound
quality as MP3 encoded at 128 kbps).
WMA is a format suitable for portable
players with limited memory. WMA also
provides the mechanism that allows music
files to contain encrypted data such as
copyright-protection information in them
in combination with Windows Media Rights
Manager.
