Förfarande och anordning för kodning/avkodning av bakgrundsljud |
摘要 |
A method and apparatus for encoding/decoding of background sounds. The background sounds are encoded/decoded in a digital frame based speech encoder/decoder. First, it is determined whether the signal that is directed to the encoder/decoder represents primarily speech or background sounds. When the signal directed to the encoder/decoder represents primarily background sounds, the temporal variation between consecutive frames and/or the domain of at least one filter defining parameter is restricted. |
