Focusrite has the Green 3 Voicebox full-function microphone processor with Focusrite EQ, compressor, de-esser, and noise-reduction/ expander.

This one-space unit combines several common studio processors in one, easy-to-use system. The three-band equalizer follows the microphone pre-amplifier and has variable high and low-stage filters to shape the overall frequency response. There is a bell-shape filter to boost presence or to "notch" out unwanted frequencies. The dynamic section has a compressor and de-esser to musically control both dynamic range and excessive sibilance at the same time. If extra noise is apparent after extreme equalization and/or compression, then the noise-reduction section may be used.
