  2. IZotope RX 2 Help Documentation 10 Interface Here is a general overview of RX's main workspace. It's a good idea to familiarize yourself with this window before moving on. RX's interface is design ed to give you a full range of tools for repairing audio. In addition to its processing modules, RX provides a range of tools.

The De-clip plug-in, available in both RX Plug-in Pack and RX Audio Editor, is designed to essentially redraw the waveform as it would have been before clipping occurred, which means that now those takes can be rescued. Before and After Example. Here's another example of De-clip cleaning up a phone interview for a documentary program. Declip repairs digital and analog clipping artifacts that result when A/D converters are pushed too hard or magnetic tape is over-saturated. Quality - controls the interpolation processing quality between low, medium, and high. Clipping threshold (dB FS)-selects the clipping level used for detection of clipped intervals.

Module & Plug-in

Overview

/omnisphere-2-crack-zip-download.html. De-clip repairs digital and analog clipping artifacts that result when A/D converters are pushed too hard or magnetic tape is over-saturated. It can be extremely useful for rescuing recordings that were made in a single pass, such as live concerts or interviews, momentary clipping in “perfect takes”, and any other audio that cannot be re-recorded.

Jan 24, 2020  iZotope RX (iZotope RX 2.exe). IZotope RX is a very powerful application designed to help its users repair audio files. This program offers an impressive amount of handy functions like denoise, spectral repair, remove hum, declip etc. Moreover, the application provides multiple selection methods, thus helping you process only the song fragments. IZotope RX 6 is a powerful, industry-leading tool for fixing audio issues. In this course, join Garrick Chow as he covers the best and latest features of iZotope RX 6, and demonstrates techniques for fixing audio problems in a variety of situations.

De-clip will process any audio above a given threshold, interpolating the waveform to be more round. Generally, the process is as easy as finding the clipping you want to repair, then setting the threshold just under the level where the signal clips.

Controls

  • HISTOGRAM METER: Displays waveform levels for the current selection as a histogram. The histogram meter helps you set the Threshold control by displaying the audio level where the waveform’s peaks are concentrated. This usually indicates at what level clipping is present in the file. The longer the line for the histogram is, the more energy is present at that amplitude.

  • HISTOGRAM ZOOM CONTROLS: The histogram’s range can be scaled if you need a better view of your signal. Use the (+) and (-) buttons to scale your display and value resolution for the De-clip module. These buttons reduce (+) and/or expand (-) the range of the threshold slider and histogram. You may want to extend the histogram range when the clipping point is lower than what you can see on a histogram or if you don’t see anything on the histogram.

    Note on histogram updating in the application vs. the De-clip plug-in

    • In the RX Audio Editor, the Histogram meter updates based on selection: Select a section of the recording where clipping is prominent and De-clip will analyze the levels of the program material. If clipping is present in the selection, it will usually appear as a horizontal line in the histogram that extends all the way across the meter.
    • In the De-clip Plug-in, the histogram runs as a real-time meter.

    What is a histogram?

    • A histogram is an analytical tool that displays how many samples are present at a given signal level over a window in time. The longer the line for the histogram is, the more energy is present at that amplitude.
    • If a lot of energy tends to collect near the top and bottom edges of a waveform, that waveform is probably clipped and distorted.

  • THRESHOLD [dB]: Defines the level used for detection of clipped intervals. Generally, this should be set just below the actual level of clipping. To set the threshold, move the Threshold slider until it lines up with the place in the histogram just below where clipping is concentrated.

    Understanding the Clipping Threshold overlays

    • Adjusting the Clipping Threshold will display a blue line within the histogram and a gray line on the waveform itself (when the De-clip Threshold effect overlay). These lines indicate the audio information that will be considered as “clipping” by the de-clip algorithm.

    Using the De-clip Threshold Effect overlay in the Spectrogram/waveform view

    • By default, De-clip Threshold is enabled in the View > Effect Overlay menu.
    • When enabled and the De-clip module is open, the De-clip threshold overly will be displayed in the spectrogram/waveform display.
    • You can adjust the Threshold controls in the De-clip module by adjusting the Threshold overlay lines in the spectrogram display.
    • You can use the mousewheel on the waveform amplitude ruler to adjust the threshold control values.

  • THRESHOLD LINK: Toggles the ability to adjust positive and negative clipping thresholds independently.

    • When this option is enabled, you can adjust the positive and negative clipping Threshold controls independently. This is useful in cases where more clipping is occurring on one side of your waveform.
    • You can also set asymmetric de-clipping thresholds directly from the waveform by toggling the lock box between the threshold controls on the waveform display.

  • SUGGEST: Calculates suggested threshold values based on the levels in your current selection.

  • QUALITY: Controls the interpolation processing quality. There are three quality modes in the De-clip module: Low, Medium, and High.

    De-clip Quality mode notes

    • Low quality mode processes very quickly.
    • High quality mode processes slowly but is capable of achieving better results.
    • In many cases you will find that Low quality mode gives you great results. To save time, always start by previewing the Low quality modes first. You can also use the Compare feature to try multiple modes and preview the results.

  • MAKEUP GAIN [dB]: Selects the gain to be applied to the selection after De-clip.

    When to use the make-up gain control

    • The De-clip process causes an increase in peak levels. The Makeup gain control can be used to prevent the signal from clipping after processing. It is also useful for matching the level after processing to unprocessed audio outside of the selection.

  • POST-LIMITER: Applies a true peak limiter after processing to prevent the processed signal from exceeding 0 dBFS.

    • De-clip usually increases signal levels by interpolating signal segments “above” the clipping point, which can make the signal clip again if the waveform format offers no headroom above 0 dBFS.
    • If the post-limiter is disabled, the restored intervals above 0 dBFS can be safely stored even without makeup gain as long as the file is saved as 32-bit float. Intervals above 0 dBFS will clip when played back through a digital-analog converter.

More Information

Suggestions for severe distortion

  • For certain situations, using the Deconstruct module to extract the noise components of the distortion can help remove additional artifacts beyond the clipped peaks in a waveform.
  • In cases where severe distortion is visible on the spectrogram, the Spectral Repair tool can be used to select those problem areas, and attenuate or replace them with undistorted audio.

Visual Examples

BEFORE & AFTER CLIP REPAIR

A waveform before and after clip repair. The after example (bottom) shows the original repaired waveform (faded) and the post-limiting waveform (bright).

UNLINKING THRESHOLD CONTROLS TO CURB ASYMMETRIC CLIPPING

This problematic waveform (grey) shears off around −13 dB on only the positive side of the waveform (the histogram on the right shows the extra positive energy of clipped audio). Extra processing of the negative side would be unnecessary, so the Threshold controls can be unlinked to process above −13 dBFS on the positive side only. The resulting waveform is drawn in blue above the grey sheared peak.

The scope:
iZotope has decided to detach four modules from its RX Audio Editor to make a nice plugin package covering some basics aspects of audio repair available on a small budget. The RX Plugin Package offers the renowned RX modules to repair clipped audio, clicks, hum and mid-high range noise, all with the quality that made RX one of the most widely-used set of tools of the industry. Since I’ve recently reviewed the RX Audio Editor, I’ll quote myself on what I’ve said about these modules on my RX5 review since they’re exactly the same - then I'll move on to the scores and closing thoughts.
  • De-clip: RX’s tool to deal with distortion problems is absurdly good and does some miracles on even the hottest and most clipped recordings you can come across. The layout is very intuitive and hard to get wrong, with some visual aid on the material’s amplitude, so it’s just a matter of setting the clipping level you want to address with the threshold slider and be amazed by the results! De-clip also features an optional make-up gain control and a peak limiter to keep things safe. Arguably one of the useful tools in RX’s arsenal and one that will likely get a lot of use when your sources are less than ideal, De-clip is a life saver. I found that applying it multiple times instead of going for a huge hit leads to better results and I couldn’t believe most things I was doing! Please ponderate my excitement a little bit and keep things in context within reason - this module will not save badly clipped mixes on a mastering situation, although it can definitely make them a lot more bearable and workable.
  • De-click: Another miracle-maker, the De-click module can do a hell lot more than just plain click-removal. Along with the De-plosive module this is one of the best tools to deal with problematic sounds from syllables with “Ps” and “Bs” - just set the click type to “thump” and make things right! When used for it's meant purposes, it is simply the best solution I’ve found to this day to deal with a lot of flexible options to deal with all sorts of clicks, crackles, thumps and all sorts of short-bursts of crappiness that might’ve plagued a recording. I got very effect results using the frequency skew to nudge it towards low or high frequency attenuations and with the click widening options, which set operating length in milliseconds for the processing. It’s so effect that it’s scary, and it manages to remove the undesired and only the undesired, leaving the rest of the content rather untouched. A real lifesaver that could very well be a plugin on its own without any fear of the competition.
  • De-hum: A set of notch and high-pass filters for cutting out electrical noise. The notch filters can act as cut-only parametric bands and the high-pass filter also features a variable slope, so in that regard De-hum can serve as general purpose and simple to use equalizer with all the quality one expects from iZotope.
  • De-noise*/Dialog De-noise (*only Dialog De-noise is available on the RX Pug-in Pack): Another one that could definitely be a plugin on its own and it would be a very competitive entry in the noise-reduction segment. Extremely effective and versatile, coming in two operating modes: a broadband mode with the entire frequency spectrum and dialog/speech mode that is optimized for the frequency range of a human voice - this last mode also reveals itself as an excellent tool for removing or attenuating hiss from any kind recording, not only dialog. In that regard, I’ve found myself using Dialog De-noise a whole lot more since most of my noise problems occurred in the top end and on few occasions I had to resort to the full-spectrum mode.
The Scores
Sound Quality - 5/5: The quality of these modules is second to none, RX is widely-adopted by professionals around the globe and that should tell us something about how good they are. I’d highlight the miracle-makers De-clip and Dialog De-noise but the quality of the De-click and De-hum are also very high. Great tools to have around as they provide a out of situations that would otherwise require a new recording altogether - something everybody knows is not always possible or feasible to do.

Izotope Rx Declip Brickwall 2


Features - 4/5: BrickwallThe RX Plugin Pack is a well-rounded product that will serve well on first-aid rescue missions and also capable of tackling further damage done to a recording. From my experience clipping and hiss are two of the most common problems and the pack readily addresses that. It also deals with the undesired clicks and electrical humming which are also frequent occurrences, so all around the plugin pack can deal with a good number of situations. My only complaint here is not about “product” feature per se - I miss an upgrade path to RX, which would put the Plugin Pack as an affordable entry step, something a lot of people would likely welcome.
Ease of use - 4/5: Very effective and simple interfaces combined with very powerful processing makes these modules a breeze to use. They’re intuitive and very well-documented so it’s quite easy to achieve excellent results and the recently launched RX Cookbook website also helps a lot and serves as a good learning source for these plugins. A couple of potential problems will arise if you want to use the De-click and De-clip as real-time plugins on your DAW mixer as they add a ton of latency (over 30k samples with the De-click). Dialog De-noise is latency free, although a bit taxing on the CPU as expected. The plugins can also be used offline on most DAWs and as a general guideline it’s advisable to commit and render what you want to free up computing power and keep latencies in check.
Bang for buck - 5/5:

I’d say that De-clip and Dialog De-noise alone are already enough reasons to get the pack, add to that the effective De-clip and De-hum as icing on the cake and the RX pack is a great acquisition if you’re not covered in the audio-repair front.
