Convert MPEG to AC3
MPEG to AC3 Conversion Software converts MPEG
files to AC3 fast. The converter is a multiple channels encoder. The software
supports 2.1, 4.0, 4.1, 5.1, 6.1, and 7.1 channels encoding for AAC, AC3, AIFF,
AU, FLAC, OGG, and WAV files. The software also supports common file format such
as MP3, M4R (iPhone ringtone), M4B (MPEG-4 audiobook), MMF, MP2, WMA, FLAC, AAC, etc. It could convert EAC3 to AAC, EVO to AAC, AU to MP3, MLP to MMF, TS to MMF, AU to OGG, and so on.
The MPEG to AC3 Conversion Software is very easy
to use and supports batch conversion. It is full compatible
with 32-bit and 64-bit Windows 10/8/7/Vista/XP/2000.
What is MPEG?
The Moving Picture Experts Group (MPEG) was formed by the ISO to set standards
for audio and video compression and transmission. Its first meeting was in May
1988 in Ottawa, Canada. As of late 2005, MPEG has grown to include approximately
350 members per meeting from various industries, universities, and research institutions.
MPEG's official designation is ISO/IEC JTC1/SC29 WG11.
The MPEG standards consist of different Parts. Each part covers a certain aspect
of the whole specification. The standards also specify Profiles and Levels. Profiles
are intended to define a set of tools that are available, and Levels define the
range of appropriate values for the properties associated with them. MPEG has
standardized the following compression formats and ancillary standards:
- MPEG-1: The first compression standard for audio and video. It was
basically designed to allow moving pictures and sound to be encoded into the bitrate
of a Compact Disc. To meet the low bit requirement, MPEG-1 downsamples the images,
as well as uses picture rates of only 24-30 Hz, resulting in a moderate quality.
It includes the popular Layer 3 (MP3) audio compression format.
- MPEG-2: Transport, video and audio standards for broadcast-quality
television. MPEG-2 standard was considerably broader in scope and of wider appeal
- supporting interlacing and high definition. MPEG-2 is considered important
because it has been chosen as the compression scheme for over-the-air digital
television ATSC, DVB and ISDB, digital satellite TV services like Dish Network,
digital cable television signals, SVCD, and DVD.
- MPEG-3: Developments in standardizing scalable and multi-resolution
compression which would have become MPEG-3 were ready by the time MPEG-2 was to
be standardized; hence, these were incorporated into MPEG-2 and as a result there
is no MPEG-3 standard. MPEG-3 is not to be confused with MP3, which is MPEG-1
Audio Layer 3.
- MPEG-4: MPEG-4 uses further coding tools with additional complexity
to achieve higher compression factors than MPEG-2. In addition to more efficient
coding of video, MPEG-4 moves closer to computer graphics applications. In more
complex profiles, the MPEG-4 decoder effectively becomes a rendering processor
and the compressed bitstream describes three-dimensional shapes and surface texture.
MPEG-4 also provides Intellectual Property Management and Protection (IPMP) which
provides the facility to use proprietary technologies to manage and protect content
like digital rights management. Several new higher-efficiency video standards
(newer than MPEG-2 Video) are included (an alternative to MPEG-2 Video), notably:
- MPEG-4 Part 2 (or Simple and Advanced Simple Profile) and
- MPEG-4 AVC (or MPEG-4 Part 10 or H.264). MPEG-4 AVC may be used on
HD DVD and Blu-ray discs, along with VC-1 and MPEG-2.
In addition, the following standards, while not sequential advances to the
video encoding standard as with MPEG-1 through MPEG-4, are referred to by similar
- MPEG-7: A multimedia content description standard.
- MPEG-21: MPEG describes this standard as a multimedia framework.
Moreover, relatively more recently than other standards above, MPEG has started
following international standards; each of the standards holds multiple MPEG technologies
for a way of application. For example, MPEG-A includes a number of technologies
on multimedia application format.
- MPEG-A: Multimedia application format.
- MPEG-B: MPEG systems technologies.
- MPEG-C: MPEG video technologies.
- MPEG-D: MPEG audio technologies.
- MPEG-E: Multimedia Middleware.
What is AC3?
Dolby Digital, or AC-3, is the common version containing up to six discrete channels
of sound. The most elaborate mode in common usage involves five channels for normal-range
speakers (20 Hz - 20,000 Hz) (right front, center, left front, right rear and
left rear) and one channel (20 Hz - 120 Hz) for the subwoofer driven low-frequency
effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates
up to 48kHz. Batman Returns was the first film to use Dolby Digital technology
when it premiered in theaters in Summer 1992. The LaserDisc version of Clear and
Present Danger featured the first Home theater Dolby Digital mix in 1995.
