Convert EAC3 to AC3
|
EAC3 to AC3 Conversion Software converts EAC3
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 OGG, MKA, AIFF, M4A (MPEG-4 audio), M4B (MPEG-4 audiobook), MPA, AC3, AAC for iPod/iPhone/iPad/iTunes/DSi, etc. It could convert TS to MP2, THD to AIFF, CAF to AC3, APE to M4B (MPEG-4 audiobook), DTS to MMF, MOV to VOC, and so on.
The EAC3 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 EAC3?
Dolby Digital Plus (DD+ or E-AC-3 (Enhanced AC-3), and sometimes incorrectly as
EC-3) is a digital audio compression scheme. It is an incompatible[1] development
of the technologies used in the earlier Dolby Digital system. E-AC-3 has a number
of improvements aimed at increasing quality at a given bitrate compared with legacy
Dolby Digital (AC-3). While legacy AC-3 supports up to 5 full-range audio channels
at a coded bitrate of 0.640 Mbit/s, E-AC-3 supports up to 13 full range audio
channels at a coded bitrate of 6.144 Mbit/s peak.
Dolby Digital Plus bitstreams are not backward compatible with legacy Dolby
Digital decoders, and decoders that output audio over legacy S/PDIF connections
must transcode the bitstreams to an older format such as PCM, AC-3, or DTS.
The codec used by Dolby Digital Plus is based on the original Dolby Digital
codec, but with several enhancements to improve coding efficiency:
- Transient pre-noise processing - to reduce "pre-noise" artifacts
before sharp transients.
- Enhanced channel coupling - which maintains phase relationships between channels,
and improves performance of matrix decoders.
- Adaptive hybrid transform processing - an improved bit allocation and quantization
algorithm.
Dolby claims that these changes can result in bitrate improvements of up to
50% while still allowing for the signal to be efficiently converted to Dolby Digital
for backwards compatibility.
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.
