A completely transparent EQ - ideal for mastering.

Linear Phase EQ
Firium builds a complex FIR (Finite Impulse Response) filter to your specifications. See the results of your EQ with the built-in spectrum analyzer. Firium will not color your audio with the introduction of non-linear phase shift.

Meet Your Match
Ever wanted to make one track sound more like another? Need to bring together takes recorded in different spaces? Firium's spectrum matching feature provides you with all this and more. Learn the frequency response of one audio source and apply it to another for technical adjustment or creative effect. (See Match)

All 50 States
Use Firium's 50 States to store EQs for instant recall or automation. Add, delete, copy, and move the EQ states you create or have Firium intelligently "fill" empty states, morphing between selected EQs. Working with States is a snap when you use the States Overview to visualize all 50 available states. (See States Overview)

Features galore
A comprehensive history and two workspaces allow you to easily compare and contrast different EQs. Edit each channel individually or choose from four linking modes to designate how changes to one channel will affect the other. Scale, smooth, or sweep your entire EQ curve. Boost or cut your signal by +/- 18 dB. Customize the spectral display to only show what is of interest to you.

Firium brings creativity to linear phase equalization.

Note: All native versions (Mac RTAS/VST/AU and Win RTAS/VST) are included with purchase.
