AAC level controller on bitstream domain
Unggul Joo, Hochong Park · 2009
In digital broadcasting services, a difference in audio level among channels and contents causes users to modify audio output level whenever they change the channels or contents. To solve this problem, a novel method to control audio level of MPEG-2/4 AAC on the bitstream domain is proposed. It is verified that the proposed method has better performance than the level control in waveform domain.
