De-essing is important in podcast mixing to reduce harsh sibilance and excessive "ess" and "shh" sounds, which, when left unaddressed, can be distracting and make the listening experience more comfortable and pleasant for your audience.

The Lindell De-esser is your go-to tool for taming those sharp, hissing esses that can plague vocal tracks. Other de-essers may have a more clinical design to them, but Lindell’s has a sound all its own that one can only describe as musical. It responds to sibilances in a much more analog way than its digital peers, and sometimes that’s exactly what you need for taming the human voice.

Even though it comes from a musical lineage, Lindell's De-esser allows you to precisely target sibilances and reduce them with the clarity befitting modern podcast productions. It’s also dead simple to use, making it the perfect tool for anyone looking to achieve a polished, professional vocal sound.
