Abstract: A variable speed reproduction of speech from memory depending on the indication of a jog dial, is accomplished by buffer memory (23) for speech sound and a jog dial (17) for controlling a read speed from this memory. Speech sound data is read out from the buffer memory (23) at a speed corresponding to the indication of the jog dial (17). The speech sound data is reproduced, independent of the jog dial (17), from a tape (13) and is written into the memory (23). A capstan motor drive circuit (18) detects the difference between the read address and the write address of the memory (23) and controls the reproduction speed of the sound speech data from the tape (13) in accordance with this difference. Since the read speed is directly controlled for the memory (23), no time delay exists between the speed command and the actual variable-speed reproduction.

Abstract: A method and an apparatus for automatically editing audio signals by determining an editing section on a recording medium having the signals recorded thereon. A first editing point is searched for on the recording medium, and the location of that point is stored in a memory. A second editing point is searched for on the recording medium. The location of the first editing point is compared with that of the second editing point. One of the two locations is set as an in-point and the other location as an out-point in accordance with the result of the comparison. The editing section determined by the in- and out-points is displayed on a screen.
