rePhase A loudspeaker phase linearization, EQ and FIR filtering tool

rePhase is a free FIR generation tool for building fully linear-phase active crossovers with arbitrary slopes.
It also let you manually compensate for the phase shifts of your loudspeakers and existing crossovers, be it active or passive.
Once generated, the FIR can be applied using any hardware (eg openDRC, BSS BLU, ...) or software (eg CamillaDSP, Equalizer APO, Foobar, ...), stereo or multi-way convolution engine.
