Media Audio (WMA)
is an audio data compression technology developed by Microsoft.
The name can be used to refer to its audio file format
or its audio codecs. It is a proprietary technology that
forms part of the Windows Media framework. WMA consists
of four distinct codecs. The original WMA codec, known
simply as WMA, was conceived as a competitor to the popular
MP3 and RealAudio codecs. WMA Pro, a newer and more advanced
codec, supports multichannel and high resolution audio.
A lossless codec, WMA Lossless, compresses audio data
without loss of audio fidelity. And WMA Voice, targeted
at voice content, applies compression using a range of
low bit rates.
A WMA file is in most circumstances encapsulated, or contained,
in the Advanced Systems Format (ASF) container format,
featuring a single audio track in one of following codecs:
WMA, WMA Pro, WMA Lossless, or WMA Voice. These codecs
are technically distinct and mutually incompatible. The
ASF container format specifies how metadata about the
file is to be encoded, similar to the ID3 tags used by
MP3 files. Metadata may include song name, track number,
artist name, and also audio normalization values.
This container can optionally support digital rights management
(DRM) using a combination of elliptic curve cryptography
key exchange, DES block cipher, a custom block cipher,
RC4 stream cipher and the SHA-1 hashing function. See
Windows Media DRM for further information.
