WMV to M4A: Extract Audio from WMV(Windows Media Video) Video to M4A(MPEG-4 Audio) with River Past Audio Converter, WMV2M4A converter, conversion
What is
WMV?
WMV stands for Windows
Media Video -- developed and controlled by Microsoft. WMV is a generic name
of Microsoft's video encoding solutions and doesn't necessarily define the technology
what it uses -- since version 7 (WMV7) Microsoft has used its own flavour of
MPEG-4 video encoding technology.
DivX video format is originally based on hacked
WMV codec.
Windows Media Format 11 adds support for HD video up to 1080P. WMF 11 runs
only on Windows XP and Vista.
Additional information is available on Microsoft
Windows Media page.
What is
M4A?
Because of its exceptional performance and quality, Advanced
Audio Coding (AAC) is at the core of the MPEG-4,
3GPP and 3GPP2
specifications and is the audio codec of choice for Internet, wireless and digital
broadcast arenas. AAC provides audio encoding that compresses much more efficiently
than older formats, such as MP3,
yet delivers quality rivaling that of uncompressed CD audio.
To encode MPEG-4 audio, you need to have River
Past MPEG-4 Booster Pack in addition to your audio software.
