Video Description: Vocal recording used to be like a black art. A lot of experience went into getting clean recordings. The Voice de-noise module can be of great help. First the Adaptive.
Overview
IZotope Customer Care. Surgical mode was the default setting in RX 6.0 Voice De-noise processing. 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. Dialogue Repair: 6 Problems You Thought You Couldn't Fix Nov 12, 2019. Some dialogue problems can’t be fixed. Distortion, errant sirens, wind gumming the microphones—it’s impossible. The truth is, with iZotope RX, you can fix all sorts of previously impossible problems. Here are six tips to get you out of a dialogue bind. The lowest cost RX 6 product is Elements at $130 dollars. Elements, just like with Standard, offers fewer tools. Elements has 23 fewer tools than standard and 33 fewer than Advanced. The bad news doesn't stop there, the excluded tools from standard make Elements quite weak. All of the high value tools have been eliminated for the price point.

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
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.
FILTER TYPE: Choosing the filter type changes the bandwidth of the noise reduction filters.
- SURGICAL Mode: Removes more unwanted noise than Gentle Mode, but makes some sacrifices in terms of timbre and can lead to musical noise artifacts.
What is musical noise?
I like nearly all of Apple’s $99 add-on sound libraries for GarageBand (Voices doesn’t do a lot for me), but I also like free. How to use downloaded packs in garageband.
- Musical noise is caused by random statistical variations of noise spectrum that cause random triggering of sub-band gates. These artifacts are sometimes described as “chirpy” or “watery” sounds left behind during the noise reduction process.

- GENTLE Mode: provides more transparent noise reduction than Surgical, but removes less high end “sizzle.”

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
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.
