The Phase module in iZotope RX can balance asymmetric waveforms by rotating signal phase. Rotating the phase of a signal changes its peak values but doesn’t change its loudness, and otherwise has no audible effect on the signal. Asymmetric waveforms can occasionally occur in audio such as dialogue, voice, and brass instruments. Making the waveform more symmetrical gives the signal more headroom.
