Overview
Voice De-noise is an intuitive, zero latency de-noiser that offers high quality results on a variety of material.
Voice De-noise can intelligently analyze speech signals and determine the best noise threshold for your signal. In a DAW, this feature can be used to write automation in case you need to override the automatic settings and correct the noise threshold by hand.
How does Voice De-noise processing work?
- Under the hood is a series of 64 psychoacoustically spaced bandpass filters which act as a multiband gate to pass or stop a signal based on user-defined threshold values.
- If a signal component is above the threshold for the filter, it will be passed (not processed).
- If a signal component is below the threshold for the filter, it will be attenuated (processed).
Controls
Izotope Rx 6 Voice Denoise
ADAPTIVE MODE: Analyzes the incoming signal and adjust the noise threshold automatically to compensate for changes in the noise floor. This can be useful for removing noise from recordings with variable noise floor and continual noisy sections, and works well for almost any recording of dialogue and spoken word.
Adaptive mode considerations
- The noise threshold settings in Adaptive Mode may be different from the settings achieved by running Learn to set the noise threshold manually.
- Because the adaptive noise threshold is continually being adjusted, it is set lower to prevent artifacts from occurring.
- The noise threshold settings in Adaptive Mode may be different from the settings achieved by running Learn to set the noise threshold manually.
LEARN: When using Manual mode, you can use the Learn button to set the noise threshold to a noise reference.
Tips for Learning a noise profile
- Find a passage of pure noise in your audio and use Learn to analyze it.
- Longer selections of noise will set the Threshold Nodes to more ideal locations.
- We recommend finding at least one second of pure noise to Learn your noise profile from.
- Find a passage of pure noise in your audio and use Learn to analyze it.
OPTIMIZE FOR DIALOGUE OR MUSIC: Because dialogue tends to be in short bursts and vocals tend to have sustained notes, we’ve added modes to provide better results when applying Voice De-noise processing.
- Optimize for DIALOGUE reacts to noise changes faster and isn’t meant to handle the noise found in sung vocals.
- Optimize for MUSIC does not attenuate sustained notes and is more transparent when applied to sung vocals.
- Optimize for DIALOGUE reacts to noise changes faster and isn’t meant to handle the noise found in sung vocals.
THRESHOLD NODES: The Threshold Node controls on the frequency spectrum display allow you to modify the noise threshold curve, which can be thought of as the “noise profile.” These six points can be adjusted manually to suit the noise currently in your signal. These controls can be automated to compensate for shifts in the audio’s noise floor.
- In ADAPTIVE Mode, the Threshold Nodes are adjusted automatically in real-time.
- In MANUAL mode, more than one Threshold Node can be selected at a time for manual adjustment by clicking and dragging anywhere on the interface.
- In ADAPTIVE Mode, the Threshold Nodes are adjusted automatically in real-time.
THRESHOLD: The master Threshold control allows you to offset all Threshold Node values by the same amount. If you find that processing is too aggressive or processing is affecting audio you want to leave unprocessed, try adjusting this control.
REDUCTION: Provides control over the maximal depth of noise reduction (in dB) that will occur per frequency band while a signal component is below its threshold. If you have your thresholds set properly and don’t like the results you’re getting, try adjusting this control.
METERING
- The Input Spectrum meter shows the level of the signal at the input of the denoiser filters.
- The Output Spectrum meter shows the level of the signal at the output of the denoiser filters.
- The Gain Reduction Region is the area between the Input and Output Spectra. This shows the amount of noise reduction processing being applied to your signal.
- The Input Spectrum meter shows the level of the signal at the input of the denoiser filters.
Voice De-noise Plug-in
Izotope Voice Denoise
Voice De-noise has been specifically designed to provide high efficiency, zero latency adaptive noise removal when inserted on a track in your DAW or NLE. The Spectral De-noise plug-in is far more resource intensive and uses higher latency.
Spectral Repair is a module available in iZotope RX 7 Standard and RX 7 Advanced audio restoration software that lets you remove and replace unwanted sounds and frequencies in audio.
Two things make Spectral Repair much more precise at removing problem sounds than simple EQ’ing or filtering: 1. visualization of the audio and 2. algorithm-based audio repair. iZotope’s detailed visualization of the audio shows you a lot more than the waveform commonly displayed in your DAW. With this visualization, you can see different aspects of the audio, and then use one of the selection tools to trace around the problem areas. This is where the algorithm-based repair comes in.
Spectral Repair analyzes the audio surrounding the part you selected and uses that information to fill in the gaps that are left after the unwanted audio is deleted. If that is a bit confusing, it’ll make more sense once we get into the different processing modes.
Modes
Attenuate: Reduces magnitude of selection compared to audio outside of selection. Good for bringing down level of unwanted sounds like door slams or chair squeaks.
Replace: Completely replaces selection with audio outside selection. Good for unwanted sounds that completely obscure the other, wanted audio.
Pattern: Finds the most similar portion of audio outside selection and uses that info to replace the selected problem audio. Use if your source audio is badly damaged and/or has repeated parts.
Partials and Noise: A more advanced version of Replace mode. Uses harmonic synthesis to replace audio. Can correct pitch modulation such as vibrato.

Izotope Rx 7 Rx Failed To Apply The Selected Processing Center
By accurately selecting the parts you don’t want in your recording and trying out the different modes, some pretty impressive audio repair is possible. I tried two different applications.
The first test was to remove a problem frequency from a snare track, without the phase issues and over-processed sound that sometimes happen with extreme EQ settings. This snare recording had a bit of muddiness in the low-mid range, so I selected the muddy frequency using the Brush tool in the RX 7 Audio Editor:
After I selected that frequency, I opened the Spectral Repair module and tried the different algorithm modes to see what worked best. I ended up going with the Attenuate mode. I turned the Strength setting all the way up to 4 to exaggerate the effect of the processing, but in a real-life situation I’d probably use 1 or 2, so the snare doesn’t get too thin-sounding. As you can see in the screenshot below, the Compare Settings window lets you preview the audio both before and after processing, and then (if you like the result) you can hit Render in the main Spectral Repair window to apply the processing.
After applying the processing, you can see the attenuated frequency on the first snare hit, as compared to the later hits:
Here’s the audio of the snare track before processing:
And after:
For a more dramatic example of removing a problem sound, I tried something different. I took a recorded track of live drums and added an obnoxious sampled saxophone note to see if Spectral Repair could deal with it. In the screenshot below you can see the saxophone note as a series of horizontal lines (probably representing the different harmonics of the note):
For this one, the Attenuate and Replace modes seemed to be leaving a gap in the audio where the selection was, without much of the original drum recording left. But the Pattern mode did an amazing job of deleting the saxophone note while leaving the drums completely audible. I had to adjust the “surrounding region length [%]” control a bit before the algorithm got the rhythm right.
However, once I did that, the results were pretty impressive:
Here’s the original drum track:
Here’s the drum track with added saxophone note:
