Dialogue Denoiser - Restore problematic vocal or production audio recordings in real time
Now available in both RX 4 and RX 4 Advanced, the low-latency Dialogue Denoiser is the most powerful denoiser focused on real-time vocals and dialogue treatment. When unwanted background and ambient noise threaten the quality of vocal recordings, the Dialogue Denoiser replaces the need for costly and time-consuming automated dialogue replacement (ADR)-ensuring professional sounding results, every time. And with an intuitive "set it and forget it" workflow that automatically adjusts to changing noise profiles, those working in high-end post production houses as well as bedroom studios will find it incredibly easy to use.

With an algorithm specifically tuned to keep dialogue as pristine as possible, the Dialogue Denoiser can treat most problems right out of the box-potentially saving you hours of time.


Spectral Repair - Visually isolate and remove unwanted sounds
With RX 4, now you can use RX Connect to unleash all the capabilities of Spectral Repair found in the standalone application with no interruption to your workflow!

Spectral Repair is the key to discovering what your waveform won't show you. Use familiar drawing tools to identify and select problem frequencies and unwanted sounds. Salvage unusable material by filling in audio gaps instantly. With a unique visualization and a variety of selection tools to use, Spectral Repair lets you get closer to your audio-and take a hands-on approach to repairing and enhancing it.

Once a problem sound has been identified and selected, the Spectral Repair algorithms are able to resynthesize the audio while taking into consideration tonal harmonics, nonlinear pitch changes like vibrato, background noise characteristics and transient events. With the power of these tools, you can remove or attenuate unwanted, interfering sounds-from barking dogs and breath noises to string squeaks, fret noise, and missed/wrong notes.


Leveler [RX 4 Advanced] & Clip Gain - Easily adjust and level the volume of vocals and instrumentals
Non-destructive clip gain is a feature in both RX 4 and RX 4 Advanced. You can draw your ideal volume curve on individual clips with node-based Clip Gain, and use instant visual feedback to balance levels against surrounding vocals or other sounds. In RX 4 Advanced, the intelligent Leveler sets your Clip Gain to a target level automatically-freeing more time for creative mix decisions.


Loudness [RX 4 Advanced] - Ensure compliance with international broadcast standards
The Loudness module quickly makes any mix compliant with the latest network standards across the world, so you can export and deliver your mix to multiple networks. Simply enter the desired True Peak and LKFS values, and click Process. The module will indicate what the loudness measurements are for your audio (integrated, short term, momentary, range loudness, and true peak); you can then select a preset or set a desired target Integrated Loudness and True Peak value for the program audio.


Ambience Match [RX 4 Advanced] - Match the environment noise of different audio recordings
Quickly match the environment noise of two different audio recordings. First, learn the source audio clip's ambient noise, then process the learned ambient noise on a target audio clip. A single slider provides control over the amount of learned ambient noise to be applied. The learned ambient noise to be added to a target audio clip will not increase the noise floor of the target file. So if there is already a loud, noisy ambient, the module will not make it noisier. The module also knows not to compound the level of the noise floor if adding the same ambient noise profile to an audio clip. You can also easily create long sections of constant ambient noise to insert under ADR recordings.


EQ Match [RX 4 Advanced] - Matches the sonic differences between audio recordings
In just two easy steps, you can ensure a consistent-sounding mix-even when using multiple audio sources. First, learn the source audio clip's EQ, then process the learned EQ on a target audio clip. A single slider offers control over how the learned EQ is applied. You can easily make smooth transition between multiple audio sources with different EQ qualities.


RX Connect - Streamline your process with a round-trip workflow
RX Connect enables you to use the powerful tools in the RX standalone application in conjunction with your audio or video editing software without slowing down productivity. First, send audio from your host application (DAW/NLE) to RX, where you can repair and enhance. Then, quickly return the new audio back to your host in place of the original audio. RX Monitor enables you to monitor your audio from the RX application through your host application (DAW/NLE). For applications like Pro Tools, which does not allow other applications to use their hardware while launched, this is an essential plug-in.


iZotope Insight [RX 4 Advanced] - Visualize your mix and comply with loudness standards
Insight is iZotope's essential metering suite, bundled with RX 4 Advanced as an additional plug-in (a $499 value). With its extensive set of audio analysis and metering tools, Insight is perfect for visualizing changes made during mixing and mastering, troubleshooting problematic mixes, and ensuring compliance with international broadcast loudness standards like BS.1770-1/2/3 and EBU R128. Additionally, you can generate a report and image of your Loudness history for use when delivering your mix to the network.

Fully customizable and scalable, Insight allows you to visually monitor all relevant information from your mono, stereo or surround mix in a convenient floating window. Load Insight into your favorite DAW or NLE to keep an eye as well as an ear on your mix at all times.


Dereverb [RX 4 Advanced] - Remove unwanted reverb from a variety of recorded material
Dereverb removes and reduces unwanted reverb from vocal and instrumental tracks, allowing you to keep audio clear and focused. Take control over the amount of ambient space captured in a recording: make large cathedrals sound like small halls and make roomy vocals sound like they were recorded in a proper studio space. With easy-to-use controls and powerful technology under the hood, it's an essential tool for anyone seeking a tighter mix.


Denoise - Reduce unwanted background noise quickly and easily
Denoise provides natural noise reduction with unparalleled clarity and control. Built with the most troublesome audio imperfections in mind, Denoise removes unwanted noise from any type of recording-such as music, old recordings, home movies, production recordings, and more. With transparent noise suppression technology that minimizes artifacts, the Denoise module is carefully designed to preserve the character of your audio. In addition, Denoise allows independent control over both tonal and broadband noise components, providing ultimate creative control over the color of the end result.

RX 4 Advanced features Adaptive Mode, which analyzes changing noise profiles and fixes audio imperfections automatically. It's the ideal choice for fast, efficient audio repair on the fly.


Declick - Eliminate clicks, crackles, pops and digital impulse noises
Declick automatically identifies and removes clicks, pops and digital impulse noises that can ruin a listening experience. Turn to Declick when polishing audio transfers and other recordings suffering from quality degradation, digital errors, mouth noises, and interference from cell phones. For the toughest click and crackle problems, Interpolate Mode allows you to make manual sample-level corrections to audio.

Decrackle is designed to treat continuous background crackle from sources such as vinyl, but can also treat problems like dry-mouthed spoken word and reed noise from woodwind instruments.


Hum Removal - Remove electrical hum and line noise
Hum Removal automatically identifies the base frequency of unwanted hum, and precisely removes it from the recording along with harmonics-ensuring a clean overall sound without electrical interference. For more complex hum and buzz removal, the module also automatically recommends when to use Denoise instead, so you'll always have the best tool at hand for the job.

The "Adaptive" mode removes hum that changes in frequency over time. Unlike traditional filters, this mode removes unwanted hum without side effects, such as the "hollow" sound introduced by comb filters.

RX4 Advanced is an invaluable tool for audio post production, audio engineering and recording, audio mastering, video editing, audio for broadcast, restoration and archiving, podcasting, and even forensic science.
