De bleed izotope что это

De-bleed

De-bleed 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. The De-bleed module learns a bleed relationship between two tracks. In the descriptions below, these two tracks are referred to as:

• BLEED SOURCE TRACK: This track contains only the bleed source audio.
• ACTIVE TRACK: This track contains the audio present in your source track (bleed), mixed in with the audio you want to preserve.

De-bleed relies on a relationship existing between your Active track and Bleed Source track in order to function properly and provide the best results. In order to properly establish the relationship between the Active and Bleed Source tracks, the following requirements must be met:

• At least two files are open in the RX Audio Editor: De-bleed requires 2 tracks (a Bleed Source Track & an Active Track) to process.
• The Bleed Source and Active Track have matching sample rates: The sample rates of the Bleed Source Track and Active Track must match in order to process using De-bleed. Using tracks of different sample rates may indicate that the tracks are not related.

Tip: How to correct sample rate differences

If you need to correct the sample rates of your bleed source and active track selections in the De-bleed module, you can use the Resample module in the RX Audio Editor to correct sample rate differences between your files, if necessary.

• The Bleed Source Track and Active Track must be time aligned within a few milliseconds of each other.
• Time aligned means that if the two files were played back together, they would sound in sync. So if the same audio events are occurring at the same points in the timeline for both the Bleed Source and Active tracks, this means they’re time aligned.

Tip: How to correct time alignment issues

You can adjust the length or timing of files in the RX Audio Editor by:

• Using the ‘Cut’ Edit operation, Command+X (Mac) or Ctrl+X (Windows), to remove the active selection.
• Insert Silence using the Signal Generator module to adjust the length of your file.

Workflow

1. Import the bleed source file (Bleed Source Track) and the file you are removing bleed from (Active Track) into the RX Audio Editor. Ensure that the files are in sync (instructions above).
2. Open the De-bleed module.
3. Ensure that the Active Track name that is displayed in the De-bleed module is the file you wish to modify.
4. In the De-bleed module, select the Source Track from the Bleed Source Track drop-down menu.
5. In the active file tab (Active Track), make a selection where the bleed is most obvious.
6. Click the Learn button in the De-bleed module. Learn analyzes the general relationship between the Bleed Source and the Active Track.
7. After the Learn pass is complete, select part or all of the Active Track and click Process.

Controls

• BLEED SOURCE TRACK SELECTION MENU: Select the Bleed Source track from this dropdown.
• ACTIVE TRACK: Displays the name of the track tab you are currently viewing.
• LEARN: Learns the relationship between the two tracks.
• BLEED PROFILE DISPLAY: After learning the bleed profile, this displays a portion of the relationship captured between the two tracks. Toggle between the Bleed Source and Active track displays to check that the bleed present in the bleed source track is present and aligned with the bleed in your active track.

Bleed active track display:

• STRENGTH: Determines the amount of bleed reduction applied during processing. Higher Strength values may result in the removal of audio you wish to preserve. It is recommended you start with lower strength values and increase the values if needed to achieve the most desirable results.
• ARTIFACT SMOOTHING: Helps to reduce or eliminate the “musical noise” that is often characteristic of FFT-based processing. Musical noise can be described as how something may sound underwater. Increase this slider if your output sounds watery, but decrease it when too much smoothing makes your audio sound dull.

RX 10 De-bleed

iZotope RX 6

Незаменимый пакет. Пользуюсь при работе с видео.

De-Noise спасает от шума любой сложности, особенно эффективно работает спектральное вычитание при помощи редактирования огибающей шума.
De-Click прогоняю практически на любой петличке, т.к. они находятся рядом со ртом артиста и записывают чересчур много деталей.
В 6-й версии добавили De-Bleed, самый распространённый случай применения — удалить из вокального микрофона шум от наушников или от метронома 🙂
Так же есть Breath Control для автоматического удаления или понижения громкости дыхания, спектральный де-ессинг и многое другое.

iZotope’s RX is best known for its audio repair and enhancement capabilities, adored by the largest broadcast and post-production facilities across the globe.

That said, RX 7, the latest version of the toolkit, also boasts various features that make it a powerful asset for commanding and elevating musical performances. Whether you’re working with post production or music production, this feature guide will overview some of the essential components that you’ll want to be aware of to get the most out of RX 7 Standard.

Overview

RX 7 Standard has two primary components: the standalone RX Audio Editor, and a collection of plugins that can be used right within your DAW. We’re going to focus primarily on the standalone editor, which hosts some of the most powerful functionalities RX 7 Standard has to offer (and also includes all of the individual plugins).

When you open up the editor, you’ll be greeted by a blank slate that looks something like this:

To get started, select an audio file from your computer using the “Open File” button, or simply drag and drop it right into RX 7 Standard. Up to 16 audio files can be opened at a time, so feel free to work on many different audio files in parallel. Once an audio file is loaded up, the GUI will display a spectrogram representation of your waveform:

Pro Tip: Want to see a standard waveform rather than a spectrogram display (or a little bit of both)? Use the slider on the bottom left of the GUI to adjust the waveform / spectrogram opacity:

This is the basic setup for using RX 7 Standard – you can now begin editing and enhancing your audio using the modules accessible via the right-hand bar. Though we won’t go through all of them, we’ll highlight some key components – starting with Music Rebalance.

Music Rebalance

One of the biggest new features introduced in RX 7 Standard is Music Rebalance, an intelligent tool that employs a machine learning-trained algorithm to identify voice, bass, percussion and other individual components within a greater mix. With Music Rebalance, a mix can be adjusted and re-animated regardless of whether you have the stems at hand. Subtly boost your bass and percussion, or fearlessly isolate or remove vocals from a track according to your needs.

Once you click on the Music Rebalance feature, it’ll open up a separate window that looks something like this:

Let’s explore some of the adjustable parameters in greater detail:

• Gain adjusts the dB level of the particular component (voice, bass, percussion, or other).
• Sensitivity sets how strict the separation algorithm will be in defining what it considers to be a particular type of sound. Low values will contain less bleed in exchange for more artifacts, while higher values will contain more bleed in exchange for less artifacts. Note that the sensitivity values are relative to one another, meaning that setting all values to 3.0 is the same as setting all values to 9.0.
• The separation algorithm determines how the module separates the sound sources, and can be set to channel independent,joint channel, or advanced joint channel mode. The channel independent mode offers the fastest but lowest quality separation, while the advanced joint channel mode takes more processing time but offers the highest quality separation.

Pro Tip: Each setting you create can be previewed, bypassed, compared, and rendered. Consider previewing a lower quality demo before comparing, since the latter can take some time to load. That said, the compare function is extremely helpful for experimenting with and A/Bing different sensitivity and gain settings before choosing one to render.

Repair Assistant

Another significant addition brought to RX 7 Standard is Repair Assistant, a feature that detects noise, clicks, sibilance, and more so that you can clean up your audio with more efficiency and effectivity than ever. You can access this intelligent helper by pressing Repair Assistant button on the top right corner of the application. This will initiate a menu that prompts you to identify a material type – dialogue, music, or other:

Once you select the appropriate source and hit “Start analysis,” Repair Assistant will begin analyzing your audio for issues in clipping, clicks, hum, and noise:

Pro Tip: Confident that your audio already sounds great? If Repair Assistant doesn’t find any issues in these categories, it will still generate some subtle cleanup processing chains for you.

After its analysis, Repair Assistant offers you three possible solutions with 10 second previews that can be easily compared and contrasted against the original audio:

Pro Tip: Use the intensity variant buttons (right below each preview spectrogram) to generate two additional intensity variations of a single processing chain:

De-bleed, de-ess, de-plosive, de-X

One of the first things you may have noticed about RX 7 Standard is how many ‘de-somethings’ occupy the list of modules:

Most of these features address the need to attenuate something undesirable that was captured in a recording, and their parameters are pretty straightforward. Let’s just quickly outline what each module targets:

• De-bleed attenuates the leakage of one signal into another, most commonly used to combat microphone and headphone bleed.
• De-click eliminates undesirable short impulses that are often the result of digital errors, mouth noises, etc.
• De-clip removes digital and analog clipping artifacts, particularly useful for salvaging one-take recordings that would be perfect if not for a moment of clipping.
• De-crackle removes clicks that are close together in time and soft in volume, great when utilized in conjunction with de-clip.
• De-ess attenuates sibilance, most commonly used with vocal recordings.
• De-hum targets and eliminates stable tonal noises, often caused by air conditioners or other electrical appliances.
• De-plosive reduces plosives in a signal, particularly handy if a pop filter was not utilized during the recording process.
• De-reverb allows you to control the amount of ambient space in a recording, using signal analysis techniques to propose optimal setting suggestions.

Depending on whether you’re doing post production, dialogue editing, music production, or something else altogether, you may find that you use some of these modules more than others. What’s key is learning to identify what issue is present in your signal, and then finding the tool that addresses your particular issue (and for many of the most common problems, Repair Assistant is there to help you out). The above modules are all available as plugins too, which means they can be quickly accessed directly within your DAW.

This concludes our tour of RX 7 Standard’s key features – there’s so much more to explore with the toolkit, but hopefully this guide gives you some starting points for you to get your feet wet. If you have a question, leave it in the comments below.
