摘要

The present invention relates to an apparatus that process framed audio data to add fade-in and/or fade-out effect with low computing speed and small memory. According to the invention, the apparatus includes deframer (10) for taking an original value of a first gain parameter from an input audio frame, first gain parameter adjuster (12) for adjusting the first gain parameter based on the original value for preset duration, and framer (14) for generating an output audio frame, which has the adjusted value for the first gain parameter.
