What is EAC3?
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:
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 AAC?
AAC has been standardized by ISO and IEC, as part of the MPEG-2 & MPEG-4 specifications. The MPEG-2 standard contains several audio coding methods, including the MP3 coding scheme. AAC is able to include 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 15 low frequency enhancement (LFE, limited to 120 Hz) channels and up to 15 data streams. AAC is able to achieve indistinguishable audio quality at data rates of 320 kbit/s (64kbit/s/channel) for five channels. The quality is close to CD also at 96 kbit/s (48kbit/s/channel) for stereo.
AAC's best known use is as the default audio format of Apple's iPhone, iPod, iTunes, and the format used for all iTunes Store audio (with extensions for proprietary digital rights management).
AAC is also the standard audio format for Sony's PlayStation 3 and is supported by Sony's Playstation Portable, latest generation of Sony Walkman, Sony Ericsson Walkman Phone, Nintendo's Wii (with the Photo Channel 1.1 update installed for Wii consoles purchased before late 2007) and the MPEG-4 video standard. HE-AAC is part of digital radio standards like DAB+ and Digital Radio Mondiale.
