HE-AAC version 2 primarily consists of three encoders: AAC, Spectral Band Replication (SBR) and Parametric Stereo Coding (PS). In the past, we have considered several modules in the three encoders. This paper defines other design issues and considers the associated solutions related to the HE-AAC version 2. The subjective and objective tests will be used to check the quality improvement.
