DesignWare® ARC™ Audio MPEG-4 aacPlus v2 Decoder for the DesignWare ARC AS211SFX and AD221BD audio processors decode up to 7.1 channel audio content. The MPEG-4 aacPlus v2 (also known as HE AAC and AAC+) decoder processes audio streams according to ISO/IEC 14496-3 standard: the AAC profile (levels 1 through 5), the HE-AAC profile (levels 2 through 5) and the HE-AAC v2 profile (levels 2 through 4). Applications include devices like MP3 players, picture frames, media players and other portable media. The DesignWare ARC Audio MPEG-4 aacPlus v2 Decoder is optimized for low processor load and small memory footprint.
