VAAC

Advanced Audio Coding is part of MPEG-2 (13818-7) and MPEG-4 (14496-3) standards from MPEG group. AAC has been tested to allow ITU-R indistinguishable quality at data rates of 320 kbps for five full bandwidth audio channels.

VAAC is VINJEY's implementation of MPEG 2/4 Low Complexity Profile decoder. VAAC was developed from scratch in accordance with MIPS and Memory requirements ` of resource constrained embedded solutions. VAAC meets full accuracy specification set by ISO for the decoder implementations. VAAC doesn't have any limitation on number channels it supports. Also, the number of channels that can be decoded depends only on the availability of Memory and MIPS.
