Third part of the ISO/IEC MPEG-4 standard
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. The first version of ISO/IEC 14496-3 was published in 1999.[ 2]
The MPEG-4 Part 3 consists of a variety of audio coding technologies – from lossy speech coding (HVXC , CELP ), general audio coding (AAC , TwinVQ , BSAC), lossless audio compression (MPEG-4 SLS , Audio Lossless Coding , MPEG-4 DST ), a Text-To-Speech Interface (TTSI), Structured Audio (using SAOL , SASL, MIDI ) and many additional audio synthesis and coding techniques.[ 3] [ 4] [ 5] [ 6] [ 7] [ 8] [ 9] [ 10] [ 11]
MPEG-4 Audio does not target a single application such as real-time telephony or high-quality audio compression. It applies to every application which requires the use of advanced sound compression, synthesis, manipulation, or playback.
MPEG-4 Audio is a new type of audio standard that integrates numerous different types of audio coding: natural sound and synthetic sound, low bitrate delivery and high-quality delivery, speech and music, complex soundtracks and simple ones, traditional content and interactive content.[ 7]
