rePhase is a 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 (openDRC, miniSHARC, Najda, ...) or software (foobar, convolver, JRiver, ...), stereo or multi-way convolution engine.

Excellent funktionality, FIR filters and linear phase corrections are very easy to implement. The manual working mode lets you choose which corrections to make. Improved documentation could be of great help.
Works, very small, no complaints.
simple and straight forward to use
