In order to improve the transmission quality of block-coded audio signals in audio communications systems (e.g. in DECT cordless telephones) when transmission errors occur, with a view to reducing to a minimum the computer processing effort and thus the cost involved and preventing any additional lag in the transmitted signal, breaks in the audio signal resulting from transmission errors are replaced with a previously generated substitution signal specific to the break in question. The substitution signal is generated, in the simplest case, by temporarily storing a signal segment which immediately precedes a current signal segment and inserting it in the gap created when the current signal segment is disrupted.
