Description: PHA-979 is a professional audio AAX, AudioUnit and VST plugin which allows you to apply an arbitrary phase shift to sound material. What is meant by the phase shift here is simultaneous shifting of all frequencies across the active frequency range of the signal by the given value in degrees. This is achieved by linear-phase design.
PHA-979 is useful during mixing sessions, especially when working with the sound material recorded through an array of microphones. In many cases this allows you to solve various phasing problems arising from the microphone placement chosen during the tracking session. In other cases this process may help you to align drums and other instruments to each other bringing punch and time coherence not attainable by the ordinary time-aligning alone.
