RX Plug-ins

Plug-in Formats

The RX 11 installer will install only the following plug-in formats:

  • AU

  • AAX (Realtime & Audiosuite)

  • VST3

  • AU ARA (Spectral Editor ARA & Music Rebalance ARA - Compatible with Logic Pro only)

All plug-in formats are 64-bit only. VST2 is no longer supported.

RX 11 Ambience Match, Dialogue Isolate, and De-rustle plug-ins are available as AAX Audiosuite plug-ins in Pro Tools only.

Learning in Audiosuite

When using RX AudioSuite plugins in Pro Tools, there are two main workflows for learning noise profiles. Each has its own benefits and drawbacks. These two workflows are outlined as follows:

Method 1 - AS Learn (Audiosuite Learn)

Make a selection and click the Learn button that appears in the bottom right of the AudioSuite plugin wrapper. With this method, learning happens offline, saving you time.

Audiosuite AS Learn

It is important to note that learning with this method also includes “handles” in the learn pass. Handles are a Pro Tools feature which extend rendered selections by a set amount. This creates a safety net of additional processed material underneath the clip edges to allow for flexibility during editing. By default, Pro Tools handles are set to 2.00 seconds. With this handle setting, for a given selection, the learn pass would also include audio 2 seconds before and 2 seconds after the selection (pictured below).

Audiosuite AS Learn Handles

This may account for unexpectedly intense learned noise profiles, because the plugin is receiving noise + dialogue or other material on either side of the noise selection. To avoid this, you can set handles to 0 via the text box next to the Render button, or learn in the middle of a long section of noise.

If you regularly use handles in your workflow and want to avoid manually turning handles on and off, then Method 2 below may provide better results for you.

Method 2 - UI Learn

  1. Make a selection and activate the Learn button that is inside the RX plugin UI, usually on the upper left side.

  2. While the learn state is active & listening (button turns blue), click Preview (button with speaker icon) in the lower left corner of the AudioSuite plugin wrapper. This passes the selected audio into the learn pass in realtime.

  3. Stop transport when you are finished learning, and the learn pass will turn itself off automatically.

Audiosuite UI Learn

A benefit to this method is that only audio you’ve selected will playback into the plugin. There is no hidden audio provided to this learning pass via Pro Tools’ handles feature. The drawback is that you must listen to your learn pass in real time. This “UI Learn” method may provide better results if you typically work with handles on (which is common in post-production).

Presets

From the Preset Manager, you can select from default presets and presets you have saved.

To browse presets, press the Presets button and click the name of any preset. If you like what you hear, press the Presets button again to hide the window.

  • ADD: Clicking this button adds the current settings as a new preset. You can type a name and optionally add comments for the preset.

    Note

    Note that characters that are not allowed in Windows file names such as * or / cannot be used as preset names and will be ignored when entered. This is to ensure consistency with the names of the underlying .xml files for easy backup and transferring.

  • REMOVE: To permanently delete a preset, select the preset from the list and click the Remove button.

  • UPDATE: When you click the Update button, your current settings before you opened the preset window are assigned to the selected preset (highlighted). This is useful for selecting a preset, tweaking it, and saving your changes to the existing preset.

  • IMPORT: Imports a preset into the preset folder.

  • FOLDER: Opens a dialog that shows your current preset folder. You can also select a new preset folder from this dialog.

  • RENAMING PRESETS: You can double click on the name of a preset to enter the edit mode and then type a new name for that preset.

  • CANCEL: Press Escape to close the preset system dialog and revert to the settings when you opened the preset manager.

History

Pressing the History button opens the History window. This view gives you a list of all of the actions you’ve performed inside the plug-in, allowing you to step back to previous settings and undo changes.

  • CLEAR: Resets the History list.

I/O Meters

  • Select plug-ins feature an input and output gain control and input and output metering.

  • In stereo instances of the plug-ins, the gain controls are linked stereo gains.

Options

General Options

Authorization & Updates

The Authoriztion and Updates section of the General Options tab includes the following options:

Host Performance
  • Enable Multicore (Spectral De-noise only) This option is available in the Spectral De-noise plug-in. Enabling this option lets RX process Spectral De-noise Quality Modes C and D more efficiently by spreading its processing across multiple computer cores.

I/O Options

The RX I/O meter displays a lower bar representing the average level (RMS) and a higher bar representing peak level. There is also a moving line above the bar representing the most recent peak level or peak hold.

  • PEAK HOLD TIME: If peak hold is on, you can choose different peak hold times. The choices are 250 ms, 500 ms, 1000 ms, 5000 ms and Infinite. If set to infinite, the peak value will be held until you click on the current peak display.

  • INTEGRATION TIME: Specifies the integration time for RMS calculation. In most RMS meters, the integration time is set to around 300 ms, which makes the RMS meter similar in ballistics to VU meters.

  • READOUT: Allows you to control what level value is displayed on top of the meters: peak or actual (real time). If set to Max Peak, the display will show the highest peak level. If set to Current, the display will reflect the meter’s current value.

  • ENABLE I/O METERS: Turns the level meters on or off.

  • SHOW PEAK HOLD: Turns the peak hold display for the level meters on or off.

Latency

Some of the processing modes in the RX plug-ins are very CPU intensive and result in a delay of the signal. That is, RX needs some time to process the audio before it can send it back to the host application. That time represents a delay when listening or mixing down.

Most modern DAWs and NLEs provide delay compensation—a means for RX plug-ins to tell the application it has delayed the signal, and the host application should “undo” the delay on the track (usually by adding compensating delays to other tracks in real-time processing, or by adjusting the rendered file after processing in offline processing). When Enable Delay Compensation is enabled in the Latency menu, we will report our latency to the host application.

If your application doesn’t support it, or skips/stutters with this option on, you can always manually correct the delay offset in the host application (manually edit out the short delay of silence). To help you perform manual correction, the delay RX introduces is shown below as Total System Delay in both samples and milliseconds.
