Getting Started with the RX Plug-in Pack


The RX Plug-in Pack is a collection of the four essential plug-ins from the RX 5 Audio Editor: De-click, De-clip, De-hum, and Dialogue De-noise. These VST/AU/AAX/RTAS audio plug-ins can be used right within your preferred audio or video editing software, as real-time inserts, or clip/region-based processes.

Dialogue De-noise

Reduces the noise floor of recordings, while maintaining the integrity and quality of the audio.


Reduces analog and digital clipping distortion.


Reduces clicks and pops made from mouth noises, digital errors, grooved media and more.


Reduces tonal hum from AC line noise, ground loops, HVAC systems and mechanical devices.

Rendering RX plug-ins offline

In any audio or video editing software that offers offline processing of audio clips using plug-ins, you can apply RX noise reduction directly to the problematic clip and render that processing, which will conserve processing power and allow you to tweak settings for each unique piece of audio. In Pro Tools and Media Composer, these would appear under the AudioSuite menu. This can be particularly helpful when a dialogue track is made up of multiple takes with different amounts of noise. By treating the noisiest clips individually with AudioSuite processes, the noise reduction can be tailored to fit each problem.

Some hosts (including Ableton Live and Logic Pro) don't currently offer offline processing, but can utilize the RX Plug-in Pack as track inserts.

Using the RX real-time insert plug-ins

All four of the plug-ins in the RX Plug-In Pack can be used as real-time inserts in any mono or stereo audio track. These can be found under the Noise Reduction or iZotope menus in the insert section of the audio mixer in your audio or video editing software. Because of the powerful capabilities of these plug-ins, some of them can introduce latency and use significant amounts of processing power. However, the Dialogue De-noise plug-in is specifically designed to provide high-efficiency, low-latency noise reduction, so that you can use it across multiple tracks without requiring significant amounts of CPU power or delay compensation.

The other plug-ins are more resource intensive, and may be best used in single instances or as rendered processes. For example: if you have a recording of a podcast with persistent hum, instead of inserting the De-hum plug-in on that channel, try fixing the whole audio file using the De-hum AudioSuite module, or by processing the audio file and then freezing the track.
