Working with multiband compression

Remember how I said a De-Esser was a frequency-specific compressor, working only…on the sibilant sounds within a track or mix?…Well a multiband compressor follows the same idea, but works across the…entire frequency range.…By splitting up the compression into multiple parts or bands, an engineer can…focus dynamic control within a specified frequency range, leaving other…frequencies untouched or being compressed separately.…An example in mastering where I would use a multiband compressor would be, let's…say, the finished mix had a bit too much dynamics in the low-end, but the rest of…the mix sounded fine, so that is to say, maybe not enough compression was added…to the bass guitar or the kick drum, that note for note, the level of the…low-end is kind of floating around.…

Now typically, we'd want to address this at the mix stage by adding more…compression to the bass instrument,…but if we've gotten to mastering and we have no other choice, we can take and…use a multiband compressor and simply focus on the low frequencies of the…
