ABSTRACT:
A method is disclosed for the joining or mixing-in or fading of two program segments which appear in the form of digital pulse sequences, free of interfering signals, particularly audio signals digitally stored on magnetic tape, whereby code word sequences which are present in both signal segments in the region of an editing location or fading location are scanned, together with their associated time codes, and are fed to respective intermediate memories. Then, by an acoustically-monitored cyclical circulation of the contents of the intermediate memories, controlled in frequency and direction, an editing location of comparable information for each program segment is determined which is free of interfering signals. A transition, controlled by the time codes is then occasioned from the first signal segment to the second signal segment or a fading of the second signal segment is occasioned relative to the first signal segment. The two time codes which are associated with the editing locations are read for carrying out a mechanical and/or electrical connection of two signal program segments which are acoustically free of interfering signals at the proper time corresponding to a common edit point identified by the two time codes.
