摘要：Early gates were based on an electronic switch that was only turned on or off according to the input signal level. Variety digital noise reductions are in both hardware and software form and these are far more detailed than gates or expanders and generally work by first separating the incoming signal into a large number of split frequency bands. Noise has been usually added to an electrical signal there is no perfect way to remove it, although there are digital process that are effective at significantly reducing the level of random noise. However, it can be good practice to assume that any noise engineer collect along the way is going to be a permanent part of the recording and that all possible ways should be taken to minimize it. This means that engineer should always optimize gain structure, un-route unused mix channels and take all other practical measures to reduce noise at the source. Even though engineers try to do the best efforts, some noise can be remaining in signal. It is physical matter but the best way is to less unwanted noise
