iZotope’s award-winning RX 6 Audio Editor is the industry standard for audio repair, restoration, and enhancement. It offers a comprehensive suite of tools focused on alleviating common to complex audio issues. Post production professionals, audio engineers, and video editors alike use RX to transform problematic recordings into production-ready audio.

The De-click module’s sophisticated algorithm analyzes audio for amplitude irregularities and smoothes them out. This means that you can use De-click to remove a variety of short impulse noises, such as clicks caused by digital errors, mouth noises, and interference from cell phones. Jan 20, 2005 The De-hum module in iZotope’s RX noise reduction software includes a series of notch filters that can be set to remove both the base frequency of the hum (usually 50 or 60 Hz), as well as harmonics that may have resulted. Compare audio repair and noise reduction features and benefits in RX Elements, RX 7 Standard, and RX 7 Advanced. IZotope Overview. De-hum automatically.

Design Philosophy

The RX 6 Audio Editor is a visual, selection-based editing environment. Most of its user interface is devoted to the Spectrogram/Waveform display, an integral part of the RX editing workflow. The display enables you to refine and visualize your audio, allowing for better recognition and selection of problem areas.

Using the spectrogram to identify audio problems

See the Identifying Audio Problems chapter for tips on using the spectrogram to spot common audio issues.

Reduce background room noise, amp hiss, and other ambient issues with Voice De-noise, fix distortion caused by clipping at your mic preamp with De-clip, take out ground hum and other tonal noise with De-hum, and handle clicks, pops, and other artifacts with De-click. With RX Elements, high quality production audio is now within your reach. De-hum is designed to remove persistent tonal noise, like the AC hum that can be caused by poor electrical grounding. De-hum includes a series of notch filters that can be set to remove both the base frequency of the hum, usually 50 Hz (Europe) or 60 Hz (USA) as well as any harmonics.

Module & Plug-in

Overview

De-reverb gives you control over the amount of ambient space captured in a recording. It can make large cathedrals sound like small halls and make roomy vocals sound like they were recorded in a treated space.

De-reverb processes audio according to the reverberant/direct ratio (also known as wet/dry ratio) detected in the signal. It can learn your audio to suggest some frequency and decay time settings, or you can estimate these yourself.

Controls

LEARN: Teaches De-reverb how much reverb is in your signal.
- The Learn feature analyzes the signal and determines the wet/dry ratio per frequency of your signal, as well as the overall rate of decay of reverb.
- When the Learn operation completes, the Reverb Profile and Tail Length controls will be set to their suggested values.
- The Learn operation can be performed on any reverberant audio.
  Recommendation
  - We strongly recommend using the Learn feature on a selection of audio that starts with some noise floor (or room tone), is several seconds long, and includes both the direct signal and its reverberant tails.
METERING
- The top meter shows a comparison between the input and output signal energy over the past five seconds of playback.
- The bottom meter shows the amount of reverb reduction over time. It is the difference between input and output plotted on a flat line.
- Both of the meters together give you an idea of what De-reverb considers reverb and help you refine your settings.
REDUCTION: Controls the applied amount of De-reverb.
- Larger amounts mean more reverb is removed.
- Smaller amounts perform less processing.
- This control represents the target wet/dry ratio for processing. In other words, if it is set very high, it will treat the signal as though it has more reverb and process it more.
  Note: Negative Reduction Values
  - Negative Reduction values will increase the amount of reverb in the signal.
