Abstract

A system for producing an edited PCM voice signal comprises means for smoothly connecting first and second signals 1, 2, e.g. on a tape, whereby to prevent the occurrence of a click sound produced by the sudden level change (Figure 3) of the reproduced sound at the interconnection of the signals. The first and second signals 1, 2 are written into a memory (8 Figure 6 not shown), the writing-in of the second signal 2 being delayed until a parameter of the signal 2 reaches a predetermined condition e.g. the levels are equal as illustrated by signals 1, 4 (Figure 4). The invention can be applied either to hand cutting editor systems or electronic cutting editor systems. <IMAGE>
