AAC, HE-AAC, HE-AAC V2 audio encoder and decoder optimized for ARM platform
AAC, HE-AAC, HE-AAC V2 audio encoder and decoder optimized for ARM9 platform
Overview
High Efficiency Advanced Audio Coding technology (HE-AAC also known as AAC+) was standardized as Part 3 of the MPEG-4 international standard. The Advanced Audio Coding (AAC) in MPEG-4 Part 3 was enhanced relative to specifications of MPEG-2 Part 7 (AAC LC and Main profiles), in order to provide better sound quality in terms of the bit rate used for encoding. HE-AAC technology combines Advanced Audio Coding (AAC) and Spectral Band Replication (SBR) algorithms. HE-AAC technology can also be advanced to HE-AAC V2 or AAC++, which features Parametric Stereo (PS) technique. The codec can operate at very low bitrates and generally outperforms other popular codecs in the 32-64 Kbps range.
