ABSTRACT
Few audio tools are as useful or abused as effects processors. A professional studio have thousands of dollars invested in these units or equivalent plug-ins. They use them to change the tonal balance of a sound, change its dynamics, manipulate its apparent environment, or even change the sound into something totally different. Somewhere, inside virtually any effects processor, the signal level has to get boosted. If it boosts things too high, the system will distort by adding fuzziness to an analog signal, or crackling to a digital one. The re-recording mixer and assistants are the only people who should adjust equalizers or processors. This is the most practical and efficient way to do things when have got an army of people working on postproduction. Processing Can Take Time The downside of non-destructive processing is that a lot of simultaneous effects can load down the CPU. This can cause problems with playback during previews, either as stuttering sound or warning beeps.
