RX 6 includes a new De-bleed module that not only works on drums, but other acoustic instruments like piano, vocals, guitar, and more. Dialogue & vocal repair RX 6 now includes new repair tools designed specifically for dialogue and vocals including Mouth De-click, Breath Control, and the innovating new Spectral De-ess module. De-bleed Remove headphone bleed from an acoustic guitar track, click track bleed from a vocal take, and fix other signal bleed issues. De-ess Tame overly aggressive sibilance. The new Spectral De-ess mode transparently attenuates sibilance with iZotope’s Spectral Shaping technology. RX 8 is the newest and most capable version of iZotope’s professional audio repair and restoration plugin, pairing next-gen audio analysis and processing with an intuitive interface. It’s designed from the ground up to be approachable for bedroom producers with the power that professionals require. De-bleed can can help reduce or eliminate bleed from headphones, click tracks, multiple mics with small amounts of cross bleed, and even some drum bleed issues. De-Ess The De-ess audio plug-in and module in iZotope RX 6 attenuates or reduces sibilance, the harsh high-frequency sounds that come from S, F, X, SH, and a soft C. RX 6 includes two.

Module & Plug-in

Overview

The De-click module’s sophisticated algorithm analyzes audio for amplitude irregularities and smoothes them out. This means that you can use De-click to remove a variety of short impulse noises, such as clicks caused by digital errors, mouth noises, and interference from cell phones.

Controls

ALGORITHM: Provides options for adjusting the configuration and processing quality of click interpolation, depending on the types of clicks and pops present in the audio.
- SINGLE BAND: Processes quickly and works well on very narrow “digital” clicks
- MULTI-BAND (PERIODIC CLICKS): Uses multi-band processing for removing regularly repeating clicks with a wider spectrum, or regular clicks that have concentrated low or high energy (like thumps or optical soundtrack perforation noise)
- MULTI-BAND (RANDOM CLICKS): Uses multi-band processing for wider vinyl clicks and thumps, with a protective algorithm for preserving periodic audio elements characteristic to certain instruments such as brass or vocals
- LOW LATENCY: Works well on mouth clicks and other clicks that cannot be handled by other algorithms. This mode has very low latency and is suitable for real-time work in RX De-click plug-in.
SENSITIVITY: Determines how many clicks are detected in the signal. Increasing sensitivity can impact plosives, which can in turn reduce or damage the original signal.
FREQUENCY SKEW: Adjusts the weighting of click removal toward higher or lower frequency clicks. Negative values are more suitable for generic clicks such as those found on vinyl recordings. A setting of zero or above targets mouth clicks in the middle frequencies.
Note
- Frequency skew is not available when using the Single Band Algorithm option.
CLICK WIDENING: Extends the repair area around detected clicks, compensating for mouth sounds such as lip smacks that have a decay.
OUTPUT CLICKS ONLY: Outputs the difference between the original and the processed signals (suppressed clicks).

Instant Process Tool [Std & Adv]

The Instant Process Tool offers a smart De-click mode, which instantly applies the active settings from the De-click or Interpolate modules. Simply put, you may make any selection, and this mode will automatically remove all clicks present in that selection. This is particularly useful for editing a dialogue file, mismatching sample rate clicks and pops, and vinyl clicks.

If you’ve made a selection under 4000 samples in length, Instant Process will automatically use the Interpolate algorithm. Interpolate will fill the selection with audio information based on the surrounding audio.

For selections above 4000 samples, Instant Process will use the current settings of the De-click module. De-click is effective on selections above 4000 samples in size, identifying clicks in relation to desirable audio, and intelligently separating and removing the clicks.

For example, if the De-click module is indicating that a preset named ‘Remove mouth clicks’ is loaded, these settings will be applied every time you use the Instant Process Tool in ‘De-click’ mode (on selections longer than 4000 samples).

RX 6 introduces the new De-Bleed module, which reduces the leakage of one signal into another, such as when vocals bleed into a guitar microphone, or when a click track fed into headphones bleeds into an open mic.

For example, in the recording I’m about to play, we’re going to hear a male vocal that has a faint clicking sound on it. Let’s see if you can hear it.

[vocal with click]

That ticking sound that we hear is the click track in the singer’s headphones bleeding into the microphone into which he’s singing. Let’s attenuate it using the new De-Bleed module.

Once I have the De-Bleed module open, I want to make sure that my active track, which is the one with the vocals and the bleed is checked here, and I want to make sure that my source track, which is the one with the click on it in my second tab here…

[click track]

Is selected in the bleed source track dropdown menu. Now, I’ll press learn. And now, I’ll press process. Now let’s hear the results that the De-Bleed module has had on our track.

For context, here’s before.

And here’s after we used De-Bleed to attenuate those clicks.
