HE-AAC v2 Decoder on ARM9E
AAC is a popular
audio coding technique recommended by MPEG committee. SBR and PS are the tools used in combination with the AAC general audio codec resulting in HE-AAC v2 (also known as Enhanced aacPlus). It provides significant increase in coding gain. In SBR, the high-band, i.e. the high frequency part of the spectrum is replicated using the low-band. The bit-rate is by far below the bit-rate required when using conventional AAC coding. This translates into better quality at lower bit-rates.It can be used in several consumer applications, like mobile streaming and download, digital terrestrial, cable & satellite television broadcasting and Internet Video on demand service....view full
