ABSTRACT OF THE DISCLOSURE A method and an apparatus for encoding and/or decoding background sounds in a digital frame based speech encoder and/or decoder including a signal source connected to a filter, said filter being defined by a set of filter parameters for each frame, for reproducing the signal that is to be coded and/or decoded, comprises the steps: detecting whether the signal that is directed to said coder/decoder represents primarily speech or background sounds and, when said signal represents primarily background sounds, restricting the temporal variation between consecutive frames and/or the domain of at least some filter parameters in said set.
