Overview

The Phase module balances 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.

Controls

Adaptive Phase Rotation

Continuously analyzes the audio selection and applies the time-variable phase rotation to both left and right channels, resulting in a symmetrical waveform with minimal signal peak levels.

Adaptive phase rotation is best used on vocal material, as it can occasionally yield pitch artifacts on musical material.

Rotation (deg)

Rotates the channel’s phase by the specified degree.

When a waveform’s phase is rotated, every frequency is rotated equally. Rotating phase by 180 degrees inverts the waveform.

Suggest

Analyzes the selection for the ideal channel-linked fixed phase for reducing overall peak levels of the signal.

More Information

Asymmetric waveforms can occasionally occur in audio such as dialogue, voice, and brass instruments.

Visual Example of Phase Rotation

The top waveform in the folloiwing image is a trumpet signal with higher peak values on one side of its waveform (meaning the waveform is asymmetrical.)
The bottom waveform in the folloiwing image has been processed by the Phase module. The processig rotated the phase of the waveform by −72 degrees to distribute its peak samples more evenly (making the waveform more symmetrical.)
