PHA-979 is a professional audio plug AU and VST allows you to apply an arbitrary phase shift to sound material. What is meant by the phase shift here is the simultaneous movement of all frequencies across the range of active signal frequency at a given value in degrees. This is achieved by designing linear phase.
In addition, CurveEQ implements spectrum matching technology that allows you to transfer the shape of the spectrum of a recording to another. In other words, this allows you to “copy” the frequency balance of proven by the existing for other mixtures are still in the process may have the opportunity to mix sound better time. This technology also helps a lot in the domain of music, as it easily diminishes any dramatic difference in the area of frequency balance between various tracks.
CurveEQ filters can be switched between modes linear and minimum phase. CurveEQ also features a customizable spectrum analyzer deeply as the one found in Voxengo plugins GlissEQ and SPAN. You can also view, save and load diagrams static spectrum for comparison and coincidence.
