	Advanced Audio Coding - Wikipedia, the free encyclopedia
		AAC was designed as an improved-performance codec relative to MP3 (which was specified in MPEG-1) and MPEG-2 Part 3 (which is also known as "MPEG-2 Audio" or ISO/IEC 13818-3).
		AAC is a wideband audio coding algorithm that exploits two primary coding strategies to dramatically reduce the amount of data needed to convey high-quality digital audio.
		AAC, which was first specified in the standard known formally as ISO/IEC 13818-7, was published in 1997 as a new "part" (distinct from ISO/IEC 13818-3) in the MPEG-2 family of international standards.

	American Adoption Congress (AAC) - Adoption Encyclopedia
		Formed in 1978, the American Adoption Congress is a nonprofit national organization of search groups and individuals interested in changing legislation, attitudes and policies in order to guarantee access to identifying information to all adopted individuals and their birthparents and adoptive families.
		The organization comprises 11 regions, and according to the AAC, its 1,500 members include agencies, search/support groups and individuals, such as adopted adults, birthparents, adoptive parents, siblings, and adoption mental health, medical and legal professionals, throughout the United States, Canada, Europe, Mexico, Australia and New Zealand.
		The AAC holds one national conference each year; regional and local conferences are also held.

	Apple - QuickTime - Technologies - AAC Audio
		AAC was developed by the MPEG group that includes Dolby, Fraunhofer (FhG), ATandT, Sony and Nokia—companies that have also been involved in the development of audio codecs such as MP3 and AC3 (also known as Dolby Digital).
		AAC compressed audio at 128 Kbps (stereo) has been judged by expert listeners to be “indistinguishable” from the original uncompressed audio source.*
		AAC compressed audio at 96 Kbps generally exceeded the quality of MP3 compressed audio at 128 Kbps.

	OVOLAB - About AAC
		AAC, which stands for Advanced Audio Coding, part of the MPEG-4 specification, is a powerful, high-quality audio codec designed to compress audio files to smaller sizes than MP3, while delivering a better quality.
		According to Apple, expert listeners have judged AAC audio files compressed at 128 kbps (stereo) to be virtually indistinguishable from the original uncompressed audio source, whereas MP3 files at the same bitrate (taking up the same amount of space on your disk) contain audible artifacts.
		AAC audio files are supported by iTunes 4 and the iPod.

	AudioCoding.com - Knowledge Base (Site not responding. Last check: 2007-10-21)
		AAC means "Advanced Audio Coding", and in the beginning it was also called MPEG-2 NBC for "Non-Backwards Compatible" as opposed to the MPEG-1 and MPEG-2 BC (with 5.1 channels) standards.
		This became more obvious with the standardization and implementation of HE AAC / aacPlus, as the older extensions were also aiming at a higher coding efficiency for low bitrates, but mostly for special purposes like speech coding.
		Transparent quality is possible which means that most of the test samples are indistinguishable from the original for most of the listeners (term defined by the EBU in 1991 and statistically implemented in their formal listening tests since then).

		AAC (Advanced Audio Coding) is one of the audio compression formats defined by the MPEG-2 standard.
		AAC used to be called NBC (Non-Backward-Compatible), because it is not compatible with the MPEG-1 audio formats.
		AAC is more efficient than MP3 (MPEG-1 Layer 3) and is the state of the art in audio compression technology.

	Fraunhofer IIS - Audio & Multimedia - MPEG-2 AAC
		It is called MPEG-2 Advanced Audio Coding (AAC) and was declared international standard by MPEG by the end of April 1997.
		The driving force to develop AAC was the quest for an efficient coding method for surround signals, like 5-channel signals (left, right, center, left-surround, right-surround; see Fig.
		MPEG-2 AAC is the consequent continuation of the truly successful coding method ISO/MPEG Audio Layer-3 developed in Erlangen.

		Advanced Audio Coding (AAC) is a wideband audio coding algorithm that exploits two primary coding strategies to dramatically reduce the amount of data needed to convey high-quality digital audio.
		Efficient audio compression is achieved by a variety of perceptual audio coding and data compression tools, which are combined in the MPEG-4 AAC specification.
		The MPEG-4 AAC standard incorporates MPEG-2 AAC, forming the basis of the MPEG-4 audio compression technology for data rates above 32 kbps per channel.

		Many teachers report having difficulty integrating AAC technology into the literacy development process and/or identifying strategies for teaching reading and spelling to a child who cannot sound out or physically write words.
		Furthermore, because of time demands of activities of daily living, therapies, and development of self-help skills, children, who use AAC and are at risk for reading problems, frequently receive less reading instruction than their normal peers (Koppenhaver, Evans, and Yoder, 1991).
		Positive attitudes of AAC users, parents, and teachers towards literacy are important.
