3. Mar 21, 2016 Taken from our An Evening with iZotope event, iZotope product specialist Brandon Carroll walks us through RX, a powerful and essential tool for audio cleanup. He uses the spectral repair function.

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]

Free iZotope RX 7 Advanced Dialog Editing Expert Tutorials In this article Supervising Sound Editor and Re-recording Mixer David Barber from Juniper Post shares how he used iZotope RX 7 Advanced as a key part of the dialogue editing stage in the audio post-production of “The Killing Of Two Lovers”. IZotope Plug-ins Featured on New Dierks Bentley Album, 'The Mountain' How RX, Neutron, and Vinyl Were Used on New Dawes Album, 'Passwords' How Ozone Shaped the Sound of.

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).

Repair Assistant

Repair Assistant makes solving your most common audio issues faster than ever. Use Repair Assistant to identify and quickly solve problem areas in your music files.

De-clip and De-hum with Repair Assistant

Izotope Rx 2 Download

Guitar clipping and hum are both common problems in music performanes. To fix these, call up Repair Assistant, instruct it to run a pass on the ‘music’ setting and press process. Repair Assistant quickly detects sonic problems and offers up suggestions which you can preview. If you like what you hear press RENDER to commit your changes. From here you can continue tweaking or keep moving.

Lastly, if you’re doing any sampling from vinyl, or working to restore audio, you can use Repair Assistant to clean up the tracks.

Common Problems, Solved

RX 7 can solve all kinds of other problems, like cleaning up a vocal performance with that has plosives, removing guitar squeaks, and even removing track bleed. Use De-plosive to remove plosives from a vocal performance, get rid of squeaks in a guitar with Spectral Repair, and attenuate breaths using Breath Control.

Music Rebalance

RX 7 also features Music Rebalance, a powerful tool that intelligently identifies vocals, bass, percussion, and other instruments in a mix and allows you to rebalance the gain of each.

The sensitivity meters in Music Rebalance determine how much of the input signal will be identified as voice by the separation algorithm. Negative values will instruct the separation algorithm to narrowly define what it considers to be vocal content in the input signal. The resulting signal will contain less audible “bleed” from the other mix elements at the cost of introducing artifacts and reduced vocal clarity. Going the other way means the opposite, fewer chances of artifacts, but more potential for bleed.

The first of three algorithms offers the most efficient real-time preview performance and processing speeds when working with the Music Rebalance module in the RX Audio Editor. When the second mode is selected, joint channel processing is applied to the input audio before determining mix element separation. Joint Channel mode offers higher quality separation results than Channel Independent mode, especially when processing stereo files with similar content on both channels (correlated signals, strong stereo image). Advanced Joint Channel mode offers the highest quality separation results, especially when processing files of high sampling rates or when processing musical content that was not tuned to an A440 scale. This mode requires longer processing times than the other two modes.

No multitracks or stems?

Lets say you need to remaster song for today’s market but you don’t have the multitracks to work with, and you’d like to bring up the vocals and turn down the percussion. With Music Rebalance, you don’t need the multitracks to solve those problems because we can shift and balance different elements of the mix like percussion, bass, and vocals right from the audio file.

Multichannel Editing

RX 7 supports up to 7.1.2 multichannel files, so if you’re editing a live recording for a DVD or preparing a surround mix for CD, you can use all your favorite modules to treat multichannel recordings. A great example of a multichannel audio issue is bows hitting the strings a bit too hard, so that the sound reverberates across the rest of the microphones.

To solve this problem, first sum all the channels together so you can see everything in the same window and treat problems globally. Now any changes you make with the modules have an effect in every channel.

I’m going to use a combination of Spectral Repair and then Interpolate. First, highlight the affected area with the time selection tool. Select a strength of 1.5, and a left and right interpolation direction, and see where this gets you. Then use Interpolate to remove any remaning clicks by creating an even finer selection over the troubled parts and processing them. Have a listen to your before an after, and go from there.

The tips and techniques listed here should go along way in helping you fix any audio problem as a relates to music production. With tools like Music Rebalance now in your arsenal, we can't wait to hear what you’ll come up with next!
