PURPOSE:To produce the optional fading properties and to attain free edition of the digital sound, by varying manually the fading properties of a reproduced signal to store the properties in a memory and controlling the level of the reproduced signal with the memory output of perform the editing the recording. CONSTITUTION:The reproduced signal of a tape 1 is fed through a terminal P1, and a part A is recorded on a tape 3 via a terminal R. The signal of a tape 2 is fed at a point L1 and through a terminal P2. The tapes 1 and 2 are driven synchronously with each other, and the head of B is switched to D of the tape 2 to produce the tape 3. The input signal is circularly recorded in a memory 12. An operation is carried out at the boundary between A and D and by means of the digital signal of A and the fader digital signal to have the fading-out. In the same way, the fading-in is carried out for D. Then the output is delivered to a switch 17 after an addition. This process is carried out by the function of a cross fade processing circuit 15. In other words, a manual fader setting mode is obtained through a control input part 9. Thus the optional fading properties can be obtained. |
