High-Efficiency AAC (HE AAC) has achieved good quality at low bit rates by reconstructing the high frequency signals through replicating the low frequency parts. The bit reservoir that decides the bit budget between the AAC for the low frequency part and the side information used to reconstruct the high frequency part will be an important module. This paper will propose a bit reservoir design for the HE AAC.
