Audio Repair and Separation for Music and Post Production
Used on countless albums, movies, and TV shows to restore damaged, noisy audio to pristine condition, RX is a post-production powerhouse. With version 8, RX brings more power and intelligent processors for music and post than ever before. Visually identify and repair problems with the standalone RX Audio Editor application, or use the real-time plug-ins in your favorite DAW or NLE.
In addition to industry-leading repair tools for post, RX 8 Standard introduces groundbreaking new features for music production. Use Guitar De-noise to manage aspects of guitar performance like amplifier hum and interference, fret squeaks, and pick attacks—resulting in a clean, controlled recording. Leverage the improved source separation tech of Music Rebalance to mix musical elements of a stereo audio file independently, or automatically create individual stems for more nuanced mixing and processing. Prepare your production audio for broadcast at optimal loudness with an all-new Loudness Control module. Whether you’re cleaning up musical performances, performing last-minute mix edits, or preparing your audio for delivery, RX 8 Standard gives you the tools to get it done in record time.

Rebalance or isolation the musical elements of a mix
Are the vocals too quiet or the drums too loud? Can’t find the original stems to your song? With Music Rebalance, no mix is “final.” Using an algorithm trained with machine learning, Music Rebalance can intelligently identify vocals, bass, percussion, and other instruments and allows you to individually enhance or isolate elements of an audio track, making remastering without multitracks possible. Isolate or remove vocals from your song, or for more problematic mixes, separate each musical element into separate stems for individual processing.
Refine your guitar recordings for clean, authentic performances
As one of the most pervasive instruments in modern music, a clean, articulate guitar track is pivotal to a high-quality music production. RX 8 Standard introduces Guitar De-noise, a quick and easy way to manage guitar-produced sounds that can interfere with your mix when affected with limiting or compression. Reduce the prominence of electrical amplifier noise and hum, fret squeaks and pick attacks to clarify your guitar recordings—without removing the all-important human performance element.
Finalize your audio levels for delivery
Loudness is more important than ever in the age of streaming media and remote podcasting. That’s why RX 8 includes an all-new Loudness Control module. With preset targets for virtually every current broadcast loudness standard, a Loudness Gate that prevents periods of silence from skewing your loudness readings, and numeric and histogram displays for integrated, short-term, and momentary loudness (and more), your music, film, television, and podcast audio is sure to be clear, intelligible, and appropriately loud.
RX 8 Standard: Features
Guitar De-noise [Standard + Advanced Only] NEW
Brand new to RX 8 Standard, Guitar De-noise allows you to refine your guitar recordings for maximum clarity in seconds. Manage sounds that can unintentionally be emphasized by the effect of compression or limiting, like electrical amp noise and interference, distracting fret or string squeaks, and harsh pick attacks. With intuitive sliders for sensitivity and gain reduction, polishing guitar performances for intelligibility and authenticity has never been easier.
Music Rebalance NEW
Music Rebalance intelligently identifies vocals, bass, percussion, and other instruments in a mix for independent gain adjustment—and it’s now stronger than ever. With improved source separation algorithms and the ability to generate stems from a stereo recording, you can easily re-animate a mix, make room for scene dialogue in post, remove or isolate vocals for a remix, or even create and export new stems for further processing and mixing. Also available as an AudioSuite plug-in for Pro Tools.
Loudness Control [Standard + Advanced Only] NEW
Prepare your recordings for final delivery with the detailed level readings and loudness management power of the all-new Loudness Control module. Instantly load preset loudness standard targets and conform your production audio to broadcast requirements in seconds, and monitor your levels using the built-in numeric and histogram readouts for integrated, short-term, and momentary loudness. Plus, resize the module to fit your display perfectly and suit your own unique workflow.
Process several audio files in one pass with the newly overhauled Batch Processor. View pertinent metadata in your audio files prior to processing, then apply a full series of processors with Module Chain, now accessible from within the Batch Processor interface. At the end of it all, export your files in multiple file formats and bit depths for optimal efficiency and organization—perfect for refining hundreds of samples for custom-made sample libraries.
32 Audio Tab Limit NEW
Time is precious when editing audio in post. To help you tackle more work faster, RX 8 doubles the previous 16-tab limit, now allowing you to view and edit up to 32 files within RX Audio Editor, so you can cover more ground in less time with greater efficiency and in-app real estate.
Horizontal Scrolling NEW
You asked, and we listened: horizontal scrolling is now built into the intuitive Spectrogram Display. Use the scroll gesture on your trackpad or mouse with your cursor to scroll through your audio across the X-axis or lightning fast edits.
Representing the latest advances in iZotope’s assistive audio technology, Repair Assistant is a game-changing intelligent repair tool that can detect noise, clipping, clicks, and more. Solve common audio issues faster than ever, simply by selecting the type of material (music, dialogue, other) and letting RX 8 Standard analyze the audio. Repair Assistant then offers different processing suggestions to help give you the best result, as well as three different intensities (light, medium, or aggressive) for each. Review and audition different suggestions, hit render, and let Repair Assistant do the rest for you!
