Sound Radix Announce SurferEQ 2 – Significant Update For Ground-breaking EQ Plug-in

Sound Radix SurferEQ 2

SurferEQ 2 is a ground-breaking pitch-tracking equalizer plug-in that tracks a monophonic instrument or vocal and moves the selected bands with the music. SurferEQ 2 can adapt its bands' frequencies relative to the music in real-time, maintaining the natural harmonic balance of the sound source and making it possible to shape the source's timbre relative to the notes being played.

SurferEQ 2 is built using a morphing filter bank comprised from unique “circuit” structures we’ve custom-built. We’ve optimized the circuits to achieve minimal group delays for excellent transient response and vibrant sound (No cookbook EQs here!)

SurferEQ's analog-like, asymmetric filters sound natural even when pushed to extremes. In addition to the High-Pass, Low-Pass, Shelf and Bell-shaped filters, we've developed a unique, eight-mode Harmonic Filter which enables to control the entire harmonic series of an instrument using just a single band of EQ.
