Tatvik’s HE-AAC
Audio Decoder implementation is one of the fastest fixed-point
implementations for Mobile and PC Platform. The implementation is
efficient in terms of low MIPS and small memory footprint. Tatvik HE-AAC
decoder supports decoding of HE-AAC v1 (AacPlus or AAC-SBR) and HE-AAC
v2 (Enhanced AACPlus or AAC-PS) bitstreams.
