Noise Reduction VST Plugins

The DeNoiser Plug-In with its integrated de-hisser delivers surgical broadband noise reduction in real-time.

The process is based on a continual analysis of the input signal in order to build a noise profile. Alternatively, use Freeze Mode to sample a section of audio containing just target noise.

Simply define the threshold below which noise is removed and use the Reduction slider to taste.

We understand the delicate balance between removing noise and retaining the character of your original recording, so have added a Warmth control to return some richness and added a DIFF function to audition only the removed noise.

MAIN FEATURES

• Separate DeHiss, Detect & Remove Sections for intuitive use 
• High-resolution display of input signal & its noise profile 
• Frequency Bias Curve to fine-tune noise threshold & reduction 
• Mid-Side mode to de-noise only side content 
• Warmth control for sweetening after noise removal 
• Make-up gain for true A/B comparisons 

Type A is a plugin inspired by a famous vintage tape encoder. The original unit was designed to be a noise reduction system for tape recording (encode stage) and playback (decode stage).

Type A emulates the encode stage, which was often misused as an enhancer, dynamically increasing the top end of a signal without introducing artefacts or altering the harmonic content. The results are similar to a dynamic EQ which adds presence and air to any track in a natural way.

FEATURES:

• Vintage Enhancer
• Multi-band Compressor with 4 Bands
• Adjustable Unit Noise
• Oversample up to 16x
• Resizable Window
• Preset system with randomizer

ADDITIONAL FEATURES

You can show/hide the drop-down panel by clicking on the arrow icon in the bottom left corner of the interface.

You’ll get access to:

• Volume for each band
• Compressor Attack and Release
• Noise volume
• VU-Meter source selector

HOW DOES IT WORK?

To limit the amount of noise generated by tape recording, early noise reduction systems used what’s called a multi-band compander (compressor/expander). The unit dynamically emphasizes the high frequencies during the encoding stage (recording to tape), so that during the decoding stage (playback from tape) the signal is attenuated, along with the typical tape noise. Type A emulates the encoding stage only.

The input signal is split into 4 bands (with the highest bands overlapping), dynamically compressed and then summed back with the dry signal. The amount of compression on each band is inversely proportional to the volume of the band. Quieter sounds get brighter while louder sounds remain almost unchanged.

This adds brightness and air without generating any new harmonic content or distortion, resulting in a more pleasant and natural enhancer compared to a typical exciter.

NOISE REDUCTION OR ENHANCER?

Introduced in 1966 with the Dolby A301 first, and then in 1970 with the Dolby 361 (with the CAT 22 card, in photos), the A-Type noise reduction was quickly misused and modded by engineers to enhance their recordings by using the encoding stage only.

The most common mod consists in disabling the two lower bands so that only the high-frequency portion of the signal is compressed, giving even more air to vocals.

This technique was labeled with many names like the Vocal Trick, Stretch Mod, Vocal Stressor, and even the “John Lennon mod”.

Oxford DeClicker

Accurately and transparently remove pops, clicks and crackle using three discrete sections. Each has a threshold and sensitivity control to define the number of events that are detected and removed. The unique Events Graph shows the level and duration of each pop, click and crackle as it’s detected in three separate colour-coded groups. 

Sometimes there will be events detected that represent audio we want to keep rather than remove. So we built the Exclude Box to further refine the number of repaired events, and also Dialogue Mode for independent control over speech in programme.

MAIN FEATURES

• Three Dedicated Sections: DePop, DeClick and DeCrackle 

• Graphic Feedback of the Energy/Duration of Detected Events 

• Excitation Displays to Help Accurately Set Thresholds 

• Exclude Box to Select Events that Shouldn’t be Repaired 

• Dialogue Mode: Independent Settings when Speech is Detected

Three Audition Modes:  

• Listen only to removed events 
• Full processed signal
• Dialogue Mode side-chain

Fast and effective removal of buzz, hum, whine and whistles.

Use the intuitive display to help isolate the fundamental frequency – it’ll constantly give you feedback on the top contenders – or define it manually with the help of a tone generator.

Don’t worry if the fundamental wanders, the default Auto Tracking Mode will follow it in real time. The harmonics of your problem fundamental frequency will also be tracked.

All that remains is to engage the default comb filter or the optional parametric EQ, and then fine-tune the content that’s removed using DIFF auditioning.

• Ultra high resolution detection and removal of unwanted: buzz, hum, whine and whistles
• Separate Detect and Remove Sections for intuitive workflow 
• Very accurate setting of fundamental over 3 frequency ranges 
• Tracking Mode to follow fundamental and its harmonics
• Comb filter for tight removal over many harmonics
• Parametric EQ for more musical removal over fewer harmonics
• Audition removed buzz for confident fine-tuning

SYBIL – Variable Frequency De-Esser. Tame vocal sibilance quickly and easily.

Sybil is designed to tame excessive vocal sibilance (ess, tsss, ch, and sh sounds), with a flexible compressor and a variable-frequency high pass filter to ensure optimum de-essing for any vocal performance.

The compressor section includes threshold, ratio, attack and release controls, and the high-pass frequency control lets you adjust which high frequency content will get compressed, to ensure that the sibilance is reduced while the rest of the voice remains pristine.

With Sybil, everything you need to get control of vocal sibilance is right at your fingertips.

MAIN FEATURES

• Tames sibilance precisely and effectively
• Threshold, attack, decay, and ratio controls
• Variable sidechain highpass frequency
• AAX Native, RTAS, VST, and Audio Units
• Mac/PC

An advanced audio noise reducer with a simple and straightforward interface

Brusfri is a highly advanced audio noise reducer, packed into a simple and straightforward interface. It is very well suited for cleaning up noisy audio recordings while retaining sound quality.

Unlike many other noise reducers on the market, Brusfri doesn’t mess with audio phasing to suppress noise (a technique that often comes with audible side effects). Instead, multiple fine-tuned gates are used to silence unwanted noise.

• 1. Attack / Threshold / Release – These parameters control all the internal expanders relatively.
• 2. Learn Button – Brusfri needs some noise to be analysed. Most of the time, this is the only thing that’s needed. Push and hold to feed audio data and create a noise profile.
• 3. Tonality – Most of the time, Brusfri does a good job in creating a noise profile that works as expected, but in some cases (especially when there’s heavy noise involved) one needs to tweak a bit.

What is that noise?!

Can we shut down the vent system for the whole building, please?

You know the feeling when you just have recorded the best take ever for your new creation and it’s time to edit when you realise there’s a constant hiss in the background interfering with the performance. It happens to us all, whether you’re working with music, film, podcasts or radio, unwanted noise is a problem that pops up now and then. With the improvement of sound quality over the years, what was once hidden behind tape hiss can now be audible and bothersome and we need noise reduction to tackle it.

Features

• Several frequency-trimmed expanders build an intelligent noise suppressor
• No phase-altering, which leaves the desired sound untouched (no squishy artifacts as in many other noise reducers)
• Intuitive and unique user interface
