This version of the HE-ACC v2 decoder implements the baseline version of the PS tool. For streams not containing Parametric Stereo data, this decoder uses the High Quality (HQ) SBR tool. It also supports the ETSI DAB standard, which specifies a Digital Audio Broadcasting system requiring a HE-AAC v2 decoder that can handle 960 samples per frame within the core AAC-LC codec, and implementation of error concealment to handle corrupted audio frames.
In addition, this decoder provides optional processing of Dynamic Range Control (DRC) to make use of any DRC information signaled in the bitstream. The library can also be configured to decode AAC-LC input streams as such that resource usage is optimal. The HE-ACC v2 decoder module is supported with CrossCore® Embedded Studio development environment.
Each module supports the Analog Devices, Inc. (ADI) Blackfin or SHARC Processor family and is a licensed product that is available in object code format. Recipients must sign or accept a license agreement with ADI prior to being shipped or downloading the modules identified in the license agreement.
