Abstract
A PCM signal editing apparatus with functions of storing in memories the edit-point proximate sample data of a first PCM audio signal reproduced from a first recording medium and that of a second PCM audio signal reproduced from a second recording medium, then reading out such sample data of the PCM audio signals at a desired speed from the memories respectively in a manner to attain a coincidence of the edit points, and cross-fading the signals at the edit-in point or edit-out point in a cross-fade time conforming with the read-out speed, thereby performing a short-time insert editing operation with high efficiency and sufficient certainty. Furthermore, the apparatus is so contrived that the editing conditions proximate to the edit points of the PCM audio signals can be aurally perceived with accuracy, and the access states of the memories are displayed by bar graphs to consequently render the editing state visually recognizable.
