EQuivocate from Eventide
EQuivocate from Eventide is free for a limited time. Powerful & Precise Human Ear EQ
EQuivocate’s auditory filters and match EQ functionality make it incredibly powerful, simple to use, and natural sounding.
EQuivocate uses filters that are modeled on the human ear. Each of the 26 critical bands tickles a different part of your inner ear, making any combination of settings sound as natural as possible. Combining this with a linear-phase filter shape that reduces pre-echo makes EQuivocate an EQ with a difference you can hear.
The price will be raised to 99 USD on October 31, 2017. (MSRP $99).
