DIVX to MPA: Extract Audio from DIVX(DivX Video) Video to MPA(MPEG Audio) with River Past Audio Converter, DIVX2MPA converter, conversion
What is
DIVX?
DivX is a brand name of products created by DivX, Inc. (formerly DivXNetworks, Inc.),
including the DivX Codec
which has become popular due to its ability to compress lengthy video segments into small
sizes while maintaining relatively high visual quality. The DivX codec uses lossy MPEG-4 Part 2 compression, also known as MPEG-4
ASP, where quality is balanced against file size for utility. It is one of several codecs
commonly associated with "ripping", whereby audio and video multimedia are transferred to a hard disk and transcoded.
Many newer "DivX Certified" DVD players are able to play DivX encoded movies,
although the Qpel and global motion compensation features
are often omitted to reduce processing requirements. They are also excluded from
the base DivX encoding profiles for compatibility reasons.
To convert from DivX video, you will need to either get the DivX codec from
www.divx.com, or use a compatible decoder
like ffdShow, which is part of CCCP.
What is
MPA?
There are three "layers" in the MPEG-1
Audio specification.
In MPEG Audio Layer-1, a simple 32-subband audio compressor using a floating
point representation for subband samples. Resolution and scale factor are stored
for groups of 12 subsamples. MP1 is only used for Philips DCC Digital Compact
cassette with data rates of 384 kbps.
Both MPEG-1 and MPEG-2 files use MPEG-1
Audio Layer-2.
MPEG-1 Audio Layer-3 becomes
the widely popular MP3.
MPEG.ORG is an excellent source for additional
information on MPEG format and usage.
To encode MPEG Audio, you will need River
Past MPEG-2 Booster Pack in addition to your audio software.
