Plugin Alliance Noise Reduction
Maybell Hughs
You can use it for most things you'd use Izotope's RX for. I use it for audio restoration or subtle noise/hum reduction on individual tracks/recordings. Comes with the typical modules (de-noise, de-hum, de-clip, de-click). Not as fully-featured powerful as RX Standard/Advanced, but it's excellent at what it does and has a very nice/intuitive interface. Great price, too, I bought it during a Black Friday sale for abour $60.
I have RX 7 Elements, but I haven't even installed it, since most of the material I work with is either from VIs or DIs, so unwanted noise is rarely an issue. Though I am about to record some vocals in a sub-optimal environment, so maybe I should pick this up just in case.
I remember, like 20 year ago, I had Nero CD burning suite and was able to use it's built-in noise removal tool to first analyze a 10-20sec sample then remove with an offline process, it was soooo good! I had a really bad recorded digital stage piano, low signal with lots of background noise and some loud annoying buzz from a bad wiring. Fortunately there was enough just noise at the beginning before the actual music started so I could take just a sample for analysis, then it cleared the whole take from most of the background noise and completely removed the buzz, leaving piano sound literally untouched. I was speechless. Is there any alternative like that nowadays? Is this Acon suite capable to do same thing?
DeNoise 2 is a plug-in designed to reduce noise such as hiss, wind noise, buzz and camera noise. The noise can be reduced automatically in the adaptive mode or after measuring the characteristics of the noise in the noise profile mode
It might not leave you speechless though, our expectations evolved too much since then. Forget how good Nero was, like everyone else, you were probably shocked at the time that there was such a denoise-ing tool to begin with, so you bet that piano sound was left 'untouched'. Now you'll be fiddling with Acon for an hour or so, for +/- 1% soft knee tweaks and careful parallel processing , to be just about content with the amount of sheen lost in the high-mids.
Mastering Suite consisting of Equalize 2, Dynamics, Multiband Dynamics, Limit and Dither.
Verberate 2, our renowned natural sounding reverb plug-in
Restoration Suite 2 with four plug-ins for audio restoration: DeNoise 2, DeHum 2, DeClick 2 and DeClip 2.
Extract:Dialogue automatically reduces background noise in dialogue recordings
DeWind:Dialogue automatically reduces wind noise from dialogue
DeRustle:Dialogue automatically reduces clothing rustle and microphone bump noise from lavalier recordings
DeBuzz:Dialogue automatically reduces buzz and hum noises such as neon light buzz, AC power hum, RF transmission interference from dialogue recordings
Transfer, an AAX plug-in that makes audio transfers between Pro Tools and Acoustica a breeze.
I can recommend the Restoration Suite 2. When I made a comparison with the corresponding RX plugins some time ago, I found that they are on the same level and one plugin (Acon DeClip or DeClick) was even better IMO, i.e. it delivered clearly a better result on my test case.
G8 is a high-quality noise gate with many tricks up its sleeve. It is both a professional dynamics workstation and an experimental amplitude effect. Use it for noise reduction, AM/granular synthesis, bouncing ball rhythm programming, tremolo, trajectory panning, transient shaping, and much, much more.
Type A is a plugin inspired by the famous Dolby A Trick technique. 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 artifacts 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.
The unit dynamically emphasises 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.
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 is a process used in audio to eliminate or attenuate unwanted noises. Working with recorded audio and analog gear will usually mean dealing with background noise, resonances, room tones, etc.
Brusfri allows you to clean up your tracks with an intelligent algorithm that identifies unwanted noise and suppresses it. It comes packed with an intuitive and straightforward interface to make things easier and smoother.
Most plugins suppress the noise by altering the phase. Even though that method can be helpful, altering those parameters can cause phase cancelation, and mono speakers will not reproduce your songs accurately.
However, Brusfri does not change the phase; instead, it attenuates noise by subtracting frequencies. That being said, I can say that this tool is a great alternative to avoid phase issues.
Clarity Vx Pro clears the audio using an advanced deep learning algorithm that delivers promising results. The main central knob, which activates the suppression, allows you to dial the amount of reduction you want. Besides noise removal, this control shares another interesting feature, the ambiance preserving option.
The Advanced Controls differentiates this plugin from its younger sibling, the Clarity Vx. The top added functionalities include a Reflections knob that restores a certain amount of the natural voice reflections without adding extra reverb. The Analysis button will process the audio as mono or stereo, achieving better results with the latter. The stereo processing adds a heavier load on the CPU than the Single mode, so bear that in mind.
In this particular case, Clarity Vx Pro uses neural networks to analyze each aspect of your waveform, providing instant corrections to your vocal track. It can automatically detect noises and other unwanted variations in your waveform and correct them on the go.
It will be imperative to set the adequate range in which ambiance will be separated from the voice. For example, if you need to remove said ambiance from your speech, the value you set on this knob will be the threshold that the processing mix will work on.
If introducing a neural network sounds too good to be true, Waves decided to go even further: you can choose between three distinct neural networks that differ in values, parameters such as bias and ratios, and statistics.
Algorithm was trained with voice samples to distinguish the frequencies, timber, and behavior of these sources and separate them from wind, traffic hum, or other types of background noise. Even though it reduces the noise automatically, you can adjust the sensitivity with the slider located on the left side of the interface.
Use three customizable eq filters to increase or reduce NR applied to the predefined frequency spots. If you want a noise reducer to work smoother, It is essential to control it per band. That being said, you can adjust and bypass the eq filters to manipulate the amount of attenuation.
You will find a sensitivity slider to adjust the threshold and a max attenuation knob that works as a ratio on the left side. Also, you have a spectrum analyzer to monitor your signal (gray) and the signal after the reduction (orange). Finally, additional functions like solo noise and eq filters will be located on the right side.
It can suppress noise in dialogues, podcasts, interviews, and most spoken recordings. It features six adjustable bands to attenuate the unwanted noise depending on the frequency. Additionally, the display provides lots of information for accurate monitoring.
With WNS, you get six independent bands to apply dynamically. The values can be modified to shape it as desired. Also, you can use the high and low cut this plugin provides to eliminate unwanted hiss or rumble.
The suggest feature was a technology introduced by Waves to analyze your audio and adjust the parameters according to a perceived noise. This functionality is beneficial because the multiple eq bands plus the smoothness and threshold sliders might confuse some users and make this plugin hard to use.
