Aac Codec He
Evolution from MPEG-2 AAC LC (Low Complexity) Profile and MPEG-4 AAC LC to HE-AACv2 Profile.High-Efficiency Advanced Audio Coding ( HE-AAC) is an for of defined as an profile in / 14496-3. It is an extension of Low Complexity (AAC LC) optimized for low- applications such as. HE-AAC version 1 profile (HE-AAC v1) uses (SBR) to enhance the (MDCT) compression efficiency in the. HE-AAC version 2 profile (HE-AAC v2) couples SBR with (PS) to enhance the compression efficiency of stereo signals.
It is a standardized and improved version of the AACplus.HE-AAC is used in standards like,. Contents.History The progenitor of HE-AAC was developed by under the trade name CT-aacPlus.
CT-aacPlus combined MPEG-2 AAC LC with the Coding Technologies invented (SBR). CT-aacPlus is the codec used by for their satellite radio service. Subsequently, Coding Technologies submitted their SBR to MPEG as a basis of HE-AAC.HE-AAC version 1 was standardized as a profile of MPEG-4 Audio in 2003 by and published as part of MPEG-4 in document ISO/IEC 14496-3:2001/Amd 1:2003.
The HE-AAC version 2 profile was standardized in 2006 as ISO/IEC 14496-3:2005/Amd 2:2006.A parametric stereo coding tool used in HE-AAC v2 was standardized in 2004 by MPEG and published in document ISO/IEC 14496-3:2001/Amd 2:2004.HE-AAC version 2 was also standardized under the name Enhanced aacPlus by for multimedia services in September 2004 (3GPP TS 26.401). It is based on the AAC LC, SBR and Parametric Stereo coding tools defined in the MPEG-4 Audio standard (and it refers to ISO/IEC 14496-3:2001/Amd.1:2003 - Bandwidth Extension, ISO/IEC 14496-3:2001/Amd.2:2004 - Parametric Coding for High Quality Audio, ISO/IEC 14496-3:2001 and ISO/IEC 14496-3:2001/Amd.1:2003/DCOR1). In addition it includes further tools such as error concealment, spline resampler, and stereo-to-mono downmix. It was also published by as TS 126 401 V6.1.0 in December 2004.Prior to the standardization of HE AAC v2 by MPEG, Coding Technologies submitted the combination of HE-AAC v1 coupled with under the name Enhanced AAC+. As a result, aacPlus v2 and eAAC+ are now common trade names that refer to HE-AAC v2. AAC+ and aacPlus are common trade names that refer to HE-AAC v1.Perceived quality Testing indicates that material decoded from 64 kbit/s HE-AAC does not yet have similar audio quality to material decoded from MP3 at 128 kbit/s using high quality encoders.
