Izotope Rx 6 Phasing Issues
Apr 23, 2017 iZotope RX 6 101: Musician's Toolbox by Matthew Loel T. Hepworth Video 6 of 24 for iZotope RX 6 101: Musician's Toolbox iZotope RX 6 has the power to clean up and restore practically any recording.
Overview
- Dec 02, 2015 Hooray! Day 2 of our BOOM Library SFX Advent Calendar. We had our first direct raffle that only ran for three days (besides the BIG RAFFLE for the Grand Prize from yesterday that runs the whole 24 days), so better chances for the early birds:-).The prize was nothing less than a copy of iZotope RX 5, one of the most essential tools our Sound Designers are using each and every day.
- Jan 24, 2017 Is there a good plugin to automatically fix phase during mastering? I found auto-align by soundradix but it is not for mastering. More for fixing mic alignments; and i have izotope rx, but I am wondering if auto-align will fix full tracks or if I have to spend a ton of time manually fixing it.
- Apr 20, 2017 Spectral Repair in iZotope RX 6 is the key to discovering what your waveform won't show you. RX 6 Instantly paint away audio problems with Spectral Repair iZotope, Inc. RX 6 Advanced 301.
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.
- Making the waveform more symmetrical gives the signal more headroom.
- Rotating the phase of a waveform, will change its amplitude characteristics. Phase rotation does not result in a time shift.
- Because the range of rotation is from −180 to +180 degrees, the Phase tool can be used for simpler purposes, such as inverting signal polarity.
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.)
Djay 2 apple music. In this video Pro Tools Expert Editor, Mike Thornton, demonstrates three powerful modules in in RX 6 Advanced: Dialogue Isolate, De-rustle, and De-wind.
Dialogue Isolate
Machine learning makes it possible to focus not on the noise we’re trying to get rid of, but the signal we’re trying to preserve. In the first portion of the video, Thornton shows off the Dialogue Isolate module. Using an audio example from a busy conference, he easily extracts just the dialogue he wants to keep, leaving in some of the background noise for believability.
De-rustle
With lavalier microphones being used more and more in recording film and TV, noise from clothing bumping up against lav mics can pose problem. It can be especially tricky to deal with this issue when the frequencies of rustling are similar to those heard in speech (often at a similar audio level, too).

The De-rustle module in RX 6 Advanced quickly reduces rustle, leaving dialogue clear and intact.
De-wind
Rx 6 Diet Pill
Whether its from an outdoor video shoot, or generated by fans from an indoor one, dealing with wind in recordings is another common issue for audio post production professionals. In this segment Thornton shows us how to remove rumbling caused by wind hitting a condenser microphone in combination with a custom preset he set up in the De-Wind module.
