MPEG-4 Part 3 or MPEG-4 Audio (formally ISO/IEC 14496-3) is the third part of the ISO/IEC MPEG-4 international standard developed by Moving Picture Experts Group. [1] It specifies audio coding methods.
Current research suggests that with direct and explicit reading instruction, AAC users can better develop their reading skills to participate in academic, vocational, and community activities. [ 25 ] [ 26 ] For AAC users, literacy skills facilitate self-expression and social interaction in face-to-face conversation and provide opportunities to ...

The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint.
AAC-LC is supported in all phones beginning with K700, phones beginning with W550 have support of HE-AAC. The latest devices such as the P990, K610, W890i and later support HE-AAC v2. Nokia XpressMusic and other new generation Nokia multimedia phones like N- and E-Series also support AAC format in LC, HE, M4A and HEv2 profiles. These also ...
High-tech systems may be dedicated devices developed solely for AAC, or non-dedicated devices that run additional software to function as AAC devices. [35] [38] These options are typically more affordable than a dedicated device. Examples of AAC applications that function on non-dedicated hardware include Avaz and Spoken.
Fraunhofer FDK AAC is an open-source [5] library for encoding and decoding digital audio in the Advanced Audio Coding (AAC) format. Fraunhofer IIS developed this library for Android 4.1 . [ 6 ] [ 7 ] It supports several Audio Object Types including MPEG-2 and MPEG-4 AAC LC, HE-AAC (AAC LC + SBR ), HE-AACv2 (LC + SBR + PS ) as well AAC-LD (low ...
[53] [62] As AAC devices are designed to be used in all areas of a user's life, there are sensitive legal, social, and technical issues centred on a wide family of personal data management problems that can be found in contexts of AAC use. For example, SGDs may have to be designed so that they support the user's right to delete logs of ...
