The Eiosis Air & Earth EQ Plug-In from Slate Digital brings the heart of musicality of the Eiosis AirEQ plug-in into the Virtual Mix Rack. In addition to the actual Air and Earth filters themselves, both modules feature resonant filters (high-cut for the Air and low-cut for the Earth), with slopes from 6 to 36 dB/oct.
Air is a new type of filter that allows you to add or restore brightness to a signal without ever sounding unnatural. You can gently add high frequencies without adding harshness or unpleasant digital artifacts, allowing you to bring an instrument to the front of a mix, make a vocal track breathe, or add subtle brilliance to an entire mix.
The Earth circuit was inspired by real transformer behavior, and it allows you to control deep and solid low frequencies. You can use it to add real girth to kick drums and bass, but it is also useful for any sub-bass tasks, like low-frequency sound effects for postproduction.
The design of both the high-cut filter (on the Virtual Mix Rack AirEQ module) and the low-cut filter (on the Virtual Mix Rack Earth module) allow frequencies to be rolled off naturally.
