ABSTRACT
To cover each and every processor and effect available for mixing engineers would be exhausting. Mono vinyls utilized lateral groove excursions to encode amplitude variations. When stereo records were introduced in 1958, there needed to be a way to encode both the left and right channels. Pitch shifters provide transposition values in the form of semitones, and often cents. Some provide wet/dry control. Harmonizers differ from pitch shifters in that they produce more than one transposed version of the input signal and are configured around musical intervals and chords. Exciters and enhancers are two terms that can be used interchangeably. Both exciters and enhancers have the role of making instruments, mixes, and masters sound better. Exciters and enhancers often involve very few controls. Transient designers, or transient enhancers, are designed specifically to accent or contain transients. Essentially, most of them are a hybrid of upward expanders and downward compressors.
