In comparison, by using stereo width VST/AU/AAX plug-ins, the output audio will be much wider than if an audio mastering limiter is unlinked.
However,
@Sadzandiuraye is right in saying that stereo enhancers (e.g. Waves Audio, Ltd. S1 Stereo Imager, iZotope, Inc. Ozone Imager, etc) are best left to mixing engineers and record producers.
Audio mastering shouldn't be creative. It should always be aligned towards a corrective approach unless the aforementioned happens to be what is required and has been asked for. Doing otherwise will in most cases ruin a mix.
In addition, there's this widespread misconception that you should always use a mid-side equalizer to filter everything below either 50 Hz, 80 Hz, 130 Hz, or even 200 Hz with a high-pass filter or use iZotope, Inc. Ozone Imager to narrow down your vertical signal.
People need to come to terms with reality and accept the fact that MONO IS DEAD.
All the mono-compatibility talk about this and that just needs to stop. Furthermore, if anyone is using a dynamic processor it sure must be unlinked completely.
