製品概要
The MPEG-4 HE-AAC v2 decoder is the combination of Advanced Audio Coding (AAC), Spectral Band Replication (SBR) and Parametric Stereo (PS), standardized as the High-Efficiency v2 profile in MPEG-4 (HE-AAC v2). The MPEG-4 HE-AAC v2 is backward compatible with AAC-LC.
This version of the HE-ACC v2 decoder implements the High Quality (HQ) SBR tool and baseline PS tool. This library for the SHARC processor is an implementation of the MPEG-4 HE-AAC v2 decoder, which is conformant to the standard defined by ISO/IEC in MPEG-4 Audio. This version will support multi-channel audio (up to 6 output channels).
