RX6 from iZotope is the latest evolution of the company's powerful audio restoration and repair tool and in this short video, expert trainer Joe Albano is here to explain to you the finer points of dealing with noisy vocal takes. We've all been there: your take has interference of some kind on it - well with RX6, that's no longer a problem!

Using a practial example of a noisy air conditioner that's been captured as part of a take, Joe shows you how to use the specialised vocal de-noising tools to identify, isolate and then remove the offending part of the signal using spectral processing. You can even choose to optiise the algorithm for spoken word or music. Check out the other videos in the course to become an RX6 master!

Spectral Repair. Spectral repair is a tool for interpolating selected areas on a time-frequency spectrogram. It is able to provide higher quality than the Declicker tool for long corrupted segments of audio (above 10 ms). I got the early upgrade at a low price, so I took the step from Izotope RX 1 to RX 2 Advanced, at the about the same price as it would cost to buy Izotope RX 2 from the start. I really like the adaptive noise reduction, it does really help when the background noise changes, and gets the job done a little quicker. Spectral De-noise is designed to remove stationary or slowly changing tonal noise and broadband hiss by learning a profile of the offending noise and then subtracting it from the signal. It can be useful for tape hiss, HVAC systems, outdoor environments, line noise, ground loops, camera motors, fans, wind, and complex buzz with many harmonics.

Learn how to quickly fix common voiceover audio issues including background noise, mouth sounds, and plosives.

Your clients expect high quality dialogue, and sometimes this can be a challenge. iZotope’s RX Audio Editor has become a go-to for sound professionals in film, TV, game audio, and broadcast to repair, enhance, and restore problematic audio quickly and easily.

The latest version - RX 6 - focuses even more specifically on solving some of the biggest issues in audio post. So we put together these quick tips and tricks for RX 6 to help you deliver clean, high quality sound to your clients.

Creating professional voiceover, narration, or podcast recordings starts with proper recording technique. Achieving crisp, clear results requires good mic positioning - on axis with the subject at an appropriate distance depending on the mic - and use of a pop filter to reduce plosives.

However sometimes resources are lacking, the unpredictable occurs, or a client delivers what sounds like a 19th-century wax cylinder recording. In situations like this, use these RX tips and tricks to fix common voiceover recording problems:

NEW:Remove mouth clicks with Mouth De-click

Sensitive microphones can bring out mechanical noises of the mouth which can be very distracting.

Remove Hi Frequency Noise Izotope Rx 8

The new Mouth De-click module in iZotope RX 6 is a de-clicker that is finely tuned to detect and reduce mouth noises including clicks and lip smacks.

While this feature is designed for use on longer audio selections to fix entire passages at once, you can also use it to remove individual clicks.

NEW: Reduce sharp sibilance with De-ess

Sibilance is the harsh high-frequency sounds that come from the letters S, F, X, SH, and a soft C. The new De-ess module in iZotope RX 6 attenuates or reduces sibilance in two modes: Classic and Spectral.

Classic Mode detects sibilants and attenuates them with a broadband gain envelope. Spectral Mode is more transparent, intelligent, and frequency-specific by only attenuating the high frequencies where sibilance is most active, thereby leaving the lower frequencies untouched.

Remove plosives with De-plosive

Remove Hi Frequency Noise Izotope Rx 2

Plosives are strong blasts of air from letters such as P, T, K and B that impair the sound of your recording. They’re typically heard as low-end thumps between 20–300 Hz, though sometimes as high as 500 Hz.

iZotope’s RX 6 provides an improved De-plosive module to identify plosives, and then separate and remove them from the audio signal while preserving the fundamental frequency and harmonics of the dialogue.

Be sure to use De-plosive before filtering the audio at all. The function uses a frequency band between 20-80 Hz to detect plosives - so if a high-pass filter has already been applied, it is possible that plosive detection may not work correctly.

NEW: Remove background noise with Dialogue Isolate

Recording in a noisy city apartment, or even forgetting to turn off the air conditioner (oops), can introduce background noise into your voiceover or narration.

The new Dialogue Isolate module in iZotope RX 6 Advanced is designed to separate spoken dialogue from complex, distracting background noise including crowds, traffic, footsteps, weather, or other noise with highly variable characteristics.

It can be particularly effective at increasing the level of dialogue in challenging low signal-to-noise ratio conditions. Quickly attenuate a non-stationary noise floor without sacrificing harmonic content of the dialogue!

Address rumble and hiss with Corrective EQ

To help mitigate steady background noise even further, use the Corrective EQ module before using Dialogue Isolate to prepare the audio file for enhancement or restoration and allow the subject to be heard more clearly and prominently.

Use Corrective EQ to remove rumble from dialogue or cut distortion overtones to increase the intelligibility of your voiceover.

Below is an example of some production audio from a boom mic, but this method can just as easily be applied to background noise in a voiceover recording.
