For a comprehensive set of audio repair tools, check out iZotope RX 12 Standard, the latest update to iZotope's audio repair software, which is considered a staple for recording, mastering, and audio-for-video postprocessing. The software can operate either as a standalone application or as a plug-in for both Mac- and Windows-based DAWs and NLEs. From fixing common audio problems like noises, distortions, and inconsistent recordings, to repairing severely damaged audio using Spectral Repair, RX can transform previously unusable audio into something usable.
New features include Music Rebalance real-time plug-in, which separates vocals, bass, percussion, and more. And Stems View, which reduces cross-signal interference, rebuilt with cutting-edge ML for sharper accuracy and better results when fixing headphone bleed on vocals or isolating drums. This 50+ tool ecosystem is everything you need to fix flaws, save performances, and serve the story. Striking the perfect balance between surgical control and rapid results, groundbreaking machine learning tech lets you work your way. With flawless audio for every scene, song, and story, RX makes the magic possible.

General Features
Restore Collection
Roll back an audio selection to any previous step in your History list to get the best combination of audio processing from any point in time with the brand-new Restore Selection feature.
When hovering your cursor over an item in the History list with a selection made in the spectrogram, an icon appears in line with the text. Clicking this icon will restore your selection to that point in history. This is the same as going back to that point in undo history, except only for your current selection.
Spectral Editor in Logic Pro
Spectral Editor allows Logic Pro users to put some of the most powerful iZotope processing and visualization to work without having to toggle between Logic and the RX Audio Editor. It combines RX Spectral Repair, RX's spectrogram, and RX interactive tools that enable engineers and producers to identify and eliminate unwanted noises—right in Logic.
Guitar De-Noise
Guitar De-noise lets you refine your guitar recordings for maximum clarity. Manage sounds unintentionally emphasized by the effects 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 is now relatively easy and transparent.
Loudness Control
Prepare your recordings for final delivery with detailed level readings and the loudness-management power of the Loudness Control module. Load preset loudness-standard targets to ensure your audio conforms to broadcast requirements, and monitor your levels using the built-in numeric and histogram readouts for integrated short-term and momentary loudness. Resize the module to fit your display perfectly and suit your unique workflow.
32-Tab Limit for Audio Tabs
Time is precious when editing audio in post. To help you tackle more work faster, RX doubles the previous 16-tab limit, allowing you to view and edit up to 32 files within RX Audio Editor. Cover more ground in less time with greater efficiency and in-app real estate.
Horizontal Scrolling
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 for lightning-fast edits.
Improved De-Hum
The De-hum module in RX 8 Elements uses an improved detection and reduction algorithm to automatically identify the base frequency of your unwanted hum and precisely remove it and its harmonics, ensuring a clean overall sound. For more complex hum and buzz removal, De-hum automatically recommends when to use De-noise instead, so you'll always have the best tool at hand for the job. Don't forget to use Adaptive mode to remove hum that changes in frequency over time.
Improved Batch Processor
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 the 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. This tool is ideal for refining hundreds of samples for custom-made sample libraries.
Improved Music Rebalance
Identify vocals, bass, percussion, and other instruments in a mix, and adjust the gain for each element. Isolate or remove elements, or split stems for tweaking in your DAW. The results sound more transparent over the previous version, nulling to a far greater degree.
Variable Time
Adjust the time-stretch amount of an audio selection without altering its pitch.
Variable Pitch
Adjust the pitch of an audio selection while preserving the time and length.
Music Rebalance
Identify vocals, bass, percussion, and other instruments in a mix, and adjust the gain for each element. Isolate or remove vocals.
Repair Assistant
Repair Assistant is an intelligent tool that detects noise, clipping, clicks, and more, allowing you to solve audio-restoration issues quickly and effectively. After analyzing any snippet of audio you select, it will provide three different options for processing, and let you make the ultimate choice.
Composite View
Composite View allows you to edit and apply processing to 32 individual audio tracks as if they were one, easily addressing audio issues that appear across multiple microphones.
De-Bleed
Working across multiple tracks, the De-bleed module reduces the leakage of one signal into another. De-bleed can help reduce or eliminate bleed from headphones, click tracks, multiple mics with small amounts of cross bleed, and even some drum bleed issues.
De-Ess
The De-ess plug-in and module attenuates or reduces sibilance (the harsh high-frequency sounds that come from S, F, X, SH, and soft-C sounds). Two modes for handling sibilance are provided. Classic Mode detects sibilants and attenuates them with a broadband gain envelope. Spectral Mode is more transparent, intelligent, and frequency-specific, and only attenuates the high frequencies where sibilance is most active, leaving the lower frequencies untouched.
Mouth De-Click
The Mouth De-click module has been finely tuned to detect and reduce mouth noises such as clicks and lip smacks—many listeners' worst nightmare. It's designed for use on longer audio selections, but it can also be used to remove individual clicks.
Breath Control
The Breath Control module intelligently detects breaths in dialogue or vocal recordings and suppresses them. Removing and reducing breaths in recordings can be a time-consuming process for dialogue editors and music producers. Breath Control can help reduce the time spent on repetitive editing without sacrificing audio quality.
Voice De-Noise
Zero-latency Voice De-noise has been designed to focus on dialogue and vocal treatment. Voice De-noise has an Adaptive mode that can adjust to a changing noise floor in real time, making it ideal for dialogue denoising. Also added are optimization modes for dialogue and music. When optimized for music, Voice De-noise excels at attenuating unwanted background noise from air conditioners and street noise to vocals in apartment recording situations.
