Abstract
The disclosure relates to a digital delay line especially suitable for broadcasting live audio programs. The memory of the digital delay line is of sufficient extent to produce a delay of about 6 seconds or more. The device is provided with a Dump button whereby one who is monitoring the program can, upon hearing an obscenity or a libellous remark, press the Dump button and change the program to real time eliminating the libellous or obscene remark. The device is provided with means to return the program to the full delay time without any or without substantial glitches.
