ABSTRACT:
An analog signal which forms part of a digital audio recording system is split into at least two signal paths in one of which it is delayed slightly before being recombined with each signal of the other signal path or paths. The delay can be effected by using a multistage filter in the delay line, which causes the signal in the delay line to be delayed for a period of time equal to a fraction of one cycle of the sampling frequency of the associated digital recording system. The slight delay eliminates or minimizes undesirable phase shifting which is created in the analog signal by the sampling frequency.
