Abstract
A method for processing a media signal, comprising: receiving, by an audio processing apparatus, an audio signal including a first channel signal and a second channel signal; estimating center sound by applying a band-pass filter to the first channel signal and the second channel signal; obtaining a first ambient sound by subtracting the center sound from the first channel signal; obtaining a second ambient sound by subtracting the center sound from the second channel signal; applying at least one of delay and reverberation filter to at least one of the first ambient sound and the second ambient sound to generate a processed ambient sound; and, generating pseudo surround signal using the center sound and the processed ambient sound is provided.
