ToneBoosters Equalizer 4 provides up to 16, non-linear, dynamic filter sections supporting over 30 different filter types. Each filter type can run in static or dynamic mode with external side chain support. Dynamic equalization includes upward and downward compression as well as upward expansion for transient equalization. Each filter can run with digital purity for pristine results, or using advanced analog circuit simulation for character and warmth. Last but not least, the integrated spectrum analyzer allows for quick and informed EQ decisions, and the unique AI assistant can provide content-type dependent EQ suggestions.
