iZotope RX 11 is a pioneer in audio restoration and enhancement. Powered by machine learning, RX’s comprehensive toolset
solves a wide range of audio problems—from the most common to the most complex—when working with music, audio post-production, and content creation.
RX 11 is available as a standalone audio editing application, including a set of software plug-ins for use
with Digital Audio Workstations (DAWs).
Correct, enhance, and refine your audio.
Using RX’s spectrogram, you can visually isolate and replace unwanted sounds like barking dogs, scraping strings, and sirens.
Address specific issues like clicks, clipping, hum, rustling, and background noise with dedicated repair modules.
Use tools to adjust the intonation of dialogue, remove reverb, customize ambience and EQ profiles,
and much more. Plus, if you need help quickly achieving great results, RX’s Repair Assistant
automatically recognizes and suggests solutions for specific issues, which you can then customize
with easy-to-use controls.
New Features in RX 11:
Machine learning algorithms in RX 11 are enhanced with state-of-the-art neural networks, enabling real-time, low-latency
dialogue isolation, high-quality fragmentation to restore balance, and increased intelligence
and speed of the Repair Assistant. Release your tracks with confidence thanks to our industry-first Loudness Optimize tool
and the new Streaming Preview module. Additionally, streamline your workflow with significantly improved
Audio Random Access (ARA) processing capabilities and additional support for ARA hosts.
Dialogue Isolation:
We’ve completely redesigned the Dialogue Isolation feature, adding dialogue reverb suppression and state-of-the-art machine learning
for lightning-fast real-time processing. Now you can suppress noise in dialogue or vocals
and control reverb with one easy-to-use module, available as a real-time plug-in
for your DAW and included for the first time in RX 11 Standard. The expanded version includes an all-new,
high-quality offline processing mode and multi-band processing.
Repair Assistant:
Clean up tracks faster than ever before, with increased precision. New machine learning technology lets
you easily refine dialogue and vocals, and make final edits with deeper controls.
The next-generation Repair Assistant transforms your reliable assistant into a lifesaver.
Streaming Preview:
There’s nothing worse than spending countless hours creating a track, only to be disappointed by how it sounds on streaming services.
That’s where the new Streaming Preview comes in. Now you can hear your tracks the way
the rest of the world will hear them and publish them with confidence. Happy with how it sounds?
You’re ready to release. Need a little tweaking? Optimize the volume or go back to your mix.
Loudness Optimization:
Have you ever released a song on a streaming platform and felt like it wasn’t as loud as your favorite tracks?
Get the most out of your masters with Loudness Optimize—an unprecedented approach to managing the LUFS algorithm,
maximizing the perceived loudness of your music after normalization. Simply click “Train,”
and let RX 11 optimize your master. No room for improvement? Sit back, relax, and release your track.
Music Rebalance:
Drums too loud? Vocals not loud enough? Bass too muddy? Easily revive an existing mix,
prepare for a remix, or create instrumental and vocal parts with Music Rebalance,
available in both standard and extended versions. Shape your sound with laser-like focus thanks to Music Rebalance’s improved note separation,
powered by advanced machine learning powered by a cutting-edge neural network.
ARA Spectral Editor:
Remove background noise, clicks, and hum from dialogue or tracks without switching between RX and your DAW or NLE with the Spectral Editor,
thanks to new digital signal processing and essential tools like gain, click removal, and noise reduction.
Currently available for Apple Logic Pro (in Rosetta mode).
A free update this summer will add additional host support for more hosts, including Avid Pro Tools and PreSonus Studio One.
Dialogue Contour:
Change the character and expressiveness of your voice with new control layers in Dialogue Contour, ensuring smooth dialogue editing.
Smooth out pitch or timbre fluctuations in voiceover recordings and seamlessly blend Frankenbikes’ elements to create a cohesive performance.
Mid/Side Mode:
Discover a new level of control over your audio with the new Mid/Side mode in RX 11.
When Mid/Side mode is enabled, you can visualize and manipulate the center and side components of your audio separately,
all within the main RX window. This opens up greater flexibility when performing repair tasks,
allowing you to address issues specific to the mid channel or side channels separately,
so you don’t overwork parts of your audio that don’t require processing.
Update Audio Devices
Update your audio device settings without having to exit and restart RX, streamlining your workflow and saving you valuable time.
Dialogue Isolate 3.0: Updated AI engine for voice isolation. Improved reverb handling
in extremely noisy recordings (e.g. interviews on a busy street).
Streaming Preview v2: Added new loudness profiles for the latest 2026 broadcast standards
(including updated audio algorithms for short videos on social media).
ARA 2 Compatibility: Significantly improved the stability of the Spectral Editor module in DAWs (Logic Pro, Cubase 14, Studio One 7)
when using ARA 2 technology.
Text-to-Speech Integration: An experimental feature has been added to the Text Navigation module for quickly matching transcriptions
with external text files, simplifying podcast editing.
Fixes
Apple Silicon Performance: Optimized the GPU load on Apple M4 processors when rendering spectrograms
in real time.
Batch Processor: Fixed a bug where files with a sampling frequency of 192 kHz
could cause the program to freeze during batch processing.
UI Bug: Fixed UI flickering on Windows 11 when using HighDPI scaling above 150%.
De-hum: Fixed a bug where automatic hum frequency search (Learn) did not work correctly
on very short audio fragments.
