What is WMA?
Windows 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
What is AU?
The Au file format is a simple audio file format introduced by Sun Microsystems.
The format was common on NeXT systems and on early web pages. Originally it was
headerless, being simply 8-bit u-law encoded data at an 8000 Hz sample rate. Hardware
from other vendors often used sample rates as high as 8192 Hz, often integer factors
of video clock signals. Newer files have a header that consists of six 32-bit
words, an optional information chunk and then the data (in big endian format).
Although the format now supports many audio encoding formats, it remains associated
with the u-law logarithmic encoding. This encoding was native to the SPARCstation
1 hardware, where SunOS exposed the encoding to apps through the /dev/audio interface.
This encoding and interface became a de facto standard for Unix sound.
