Currently,
There are many popular audio file formats and they
own respective advantages and disadvantages. The following
introduction is just brief comparison.
WAV
This is a standard audio format of ripping data sound
in Windows. Due to the Microsoft's influence, it has
been a universal digital sound file format and almost
all audio processig softwares supporting WAV. Because
WAV is an uncompressed audio format, so, WAV files
is large and not suitable to spread in internet.
MP3
MP3
(MPEG Layer III) developed by Fraunhofer Research
(the leading MPEG research institute at Germany and
also the people who build the MP3 codec for Internet
Explorer), the algorithm is open and free for anyone
to use. MP3 has become a source of great controversy
as it facilitates the transfer of CD quality music
on portable media and the internet. Despite the complains
of commercial entertainers MP3 has become a standard
in music broadcasting. Supported in popular packages
like Winamp and Internet Explorer, MP3 only requires
a 486 to play on average bitrates.
OGG
Vorbis
OGG Vorbis is another porpual audio formats on the Internet.
OGG Vorbis is an open source digital audio technology
designed to compete with MP3. Unlike MP3, OGG Vorbis
is royalty free for developers and end users. OGG Vorbis
claims a superior psychoacoustic model that yields better
sounding files than MP3 at comparable bitrates.
VQF
VQF is an audio compression format developed by NTT
company and bought by Japanese YAMAHA company. This
technolody is a sharp competition with MP3. Its major
advantage is higher compression rate and better sound
quality than MP3. YAMAHA said so to its proponents.
Because VQF is an exclusive format of YAMAHA company
and get limited support broadcaster, so its influence
is not so good as MP3. VQF is dependent on the broadcaster
of YAMAHA. Ohters, such as WinAMP need to install
support software.
RAM
The two extensive names mean a file format suitable
for digital audio technology in internet developed
by Real company. For its oriented goal is instant
spread in internet£¬so it is far below than
MP3 in Hi-Fi, whereas,it is outstanding and transcendent
in low-Fi.To air RA, the Real Player is necessary.
WMA
WMA (Windows Media Audio) You may have encountered
Windows Media Audio under the name of "ASF".
ASF is Microsoft's specification for streaming, essentially
a wrapper format. WMA is a lossy audio compression
algorithm which works only as part of the Windows
media player and not as a standard Windows codec (so
that you may not convert WMA files to other formats). |
