GPU DeClicker is a free program for Microsoft Windows systems to remove 'clicks', 'pops', 'bit rots' and other types of noise from audio files. Designed primarily for audio files recorded from vinyl disks, GPU DeClicker removes noise from any supported audio file you throw at it. The current version of the program is listed as beta. Restoration Suite 2 — a Giant Leap in Audio Quality. Restoration Suite 2 is a suite of four cutting edge plug-in for audio restoration and noise reduction. DeNoise 2; is a plug-in designed to reduce noise such as hiss, wind noise, buzz and camera noise. These run as VST's rather than standalone apps, requiring a free VST host program to use them in real time. I found that the Izotope product could be tweaked to very similar transparent performance as ClickRepair, but it requires a little more CPU juice, and thus a more modern mini-PC than the bargain one I purchased.

It comes in with three noise reduction effects Oxford DeClicker, DeBuzzer, and DeNoiser. With the DeClicker plugin, you can edit the audio without disturbing the rest of it. Whereas, the DeNoiser comes in with a ‘warmth' feature that is where you can fill in some of the frequency that vanishes as soon as you apply the noise reduction to the. At your place, I would proceed trial with own material, some free time and all mentioned suites - RX, Acon and Sonnox Restore (this requires an iLok for demo). I haven't tried latest Sonnox and don't know, if they updated also algorithms besides new UI and platform support, but with broadband noise removal I preferred the RX.

One of the greatest challenges every engineer faces is unwanted noise. As we know from discussing studio soundproofing, bending sound to our will takes a bit of effort. The nature of recording means that sometimes unwanted ambiance or other sounds will find a way in. And if you lack proper soundproofing, this battle becomes that much more difficult. Fortunately, we have a remedy: noise removal.

How does noise removal work?

With any signal comes noise. The stronger the signal, the less noise. But no signal lacks noise entirely. So, some smart engineers began looking for ways to reduce as much noise as possible in any given signal. Effective noise reduction techniques in music production began in the 1960s with Ray Dolby. At that time, the Dolby Tape A method emphasized four frequency bands during recording, then lowered them during playback. A decade later Philips came up with its own noise removal method, dynamic noise limiting (DNL). This circuitry could affect any source when played back, making it widely popular.

These early pioneers of noise removal paved the way for more recent digital noise removal algorithms and plugins. However, the principle remains the same from the ’60s to now. Without getting too technical, noise removal programs hone in on specific frequencies, either during recording or playback. Once targeted, the level of these frequencies can be reduced. You can determine how much you want to reduce these frequencies by setting parameters, as well as what you don’t want to be affected.

What causes unwanted noise?

In short, energy. We don’t live in a vacuum out in space. The air around us carries sound waves. Also, anything that produces or uses electricity gives off a subtle (or not so subtle) hum. This could be your refrigerator down the hall, your Peavey 6505+, or the audio cables for your direct input bass track. Some ambient sound will creep into even the most vacuum sealed, soundproofed lockbox of a studio.

Aside from background noise, clicks, crackles, and pops can occur for a variety of reasons. When recording vocals or voiceovers, these noises can occur simply from mouth movements. The slip of a tongue or lip can result in some crazy (and funny) noises. Besides human error, electronic glitches with cables, DAWs, preamps, and any other piece of gear can also yield some startling roars.

The good news here is that most of these hums, hisses, clicks, and crackles are either brief or consistent. For instance, background noise given off by a circuit usually hums around the same frequency throughout. And crackles or pops typically only last a fraction of a second. These facts make noise removal much easier.

Different techniques to remove or reduce noise

The advent of noise removal opened the door for much higher quality recordings. But with great power comes great responsibility. If we consider how noise removal works, it becomes clear that going too far could seriously interfere with the raw audio, eliminating wanted frequencies or idiosyncrasies. On the other hand, playing it safe won’t do much to enhance the audio quality. Let’s look at some methods for reducing noise, and how to strike that perfect balance.

1. Noise removal tools in audio editors

The free audio editing program Audacity offers its own noise removal effect. The noise removal software analyzes a selected portion of audio that features the unwanted sound (“Get noise profile”). Once it collects this data, the program will pick out that specific noise and reduce its prevalence in another selected segment. You can change some parameters like the amount of noise reduction, sensitivity, smoothing, and attack/release time.

For a free effect within a free program, this noise remover does a great job, though it takes some time to get used to the parameters. One drawback of this method is that it destructively alters the audio. You can always undo any change you make, of course, but any final change augments the waveform permanently. So always keep a copy of the raw audio if using an audio editor.

Some of the best audio editing programs feature powerful noise removal tools out of the box. Both SoundForge Pro and WaveLab Pro include their own versions of noise removal technology. The former has a DeHisser and DeClicker. The latter offers a DeClicker, DeCrackler, DePopper, DeBuzzer, and DeNoiser. Each of these is designed for specific types of unwanted noise and can greatly improve a muddy mix.

2. Gating and automation

Free Declicker Vst

Though technically not a noise removal tool, noise gates can come in handy for reducing unwanted sound when there’s no signal. A noise gate works a lot like a compressor or limiter. Basically, you set the threshold so that no sound below that level can enter. This way you can prevent a subtle hiss from making its way into your recording. Parameters like attack, release, and hold can be adjusted. Some modern noise gate plugins feature a lookahead option, which turns the gate on just before transients.

Automation offers another option. Using mix automation to reduce noise shouldn’t be your first option unless you’re dealing with a very short sample. For instance, if you’re editing a voiceover line or two, using automation to silence the passages between sentences can make a big difference. Or maybe one signal is hotter than another, resulting in increased amplitude and noticeable hiss. You can use automation to bring these sections down as well. It won’t eliminate the hiss, but it provides a good start.

3. High-end plugins

In addition to the built-in tools of audio editors and DAWs, several great noise reduction plugins exist as well. Waves boasts two of the most effective ones: X-Noise and WNS Noise Suppressor. X-Noise primarily deals with unwanted hiss in audio tracks. The simple layout gives you all the control you need: threshold, attack/release, shelf, and gain reduction. The WNS plugin goes even further, and really comes in handy in post-production. The plugin offers six bands of real-time suppression control, full automation, recall, and more. Other great plugins include Cedar Audio DNS One, iZotope RX2 and Sonnox Oxford Denoiser.

Conclusion

While the terms “noise removal” and “noise reduction” are used synonymously, the latter is a bit more accurate. The truth is, you simply can’t remove 100% of unwanted noise. You can get pretty darn close, where only Superman or a really healthy dog could discern it. A good mix with proper EQ and filtering will also mask a good deal of hiss or background noise.

So just remember that when it comes to any recording, the front-end comes first. No amount of post-production mastery can completely fix a bad recording filled with hisses and pops. Ask yourself, are your cables functioning well? Is your CPU fast enough? Is your room properly treated and soundproofed? In addition to these questions, consider what type of mix you’ll want in the end. If you desire a raw sound, some background noise might not break the recording. But a squeaky clean mix will require more refinement. In this way, noise removal is as much an artistic choice as a technical necessity.

Restoration Suite 2 — a Giant Leap in Audio Quality

Restoration Suite 2 is a suite of four cutting edge plug-in for audio restoration and noise reduction:

• 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. New in version 2 are dynamic noise profiles that capture the dynamic properties of the noise so that noise that fluctuates over time, such as wind noise, can be effectively reduced. The new algorithm has also been greatly improved and is now even less prone to typical de-noising artifacts.
• DeHum 2 targets hum and buzz typically introduced by poorly grounded electrical equipment, but also other tonal noise sources like electrical motor noise. The hum detection algorithm has been improved in version 2 and there’s now a new Scan button that automatically fine tunes the fundamental hum frequency.
• DeClick 2 is designed to remove impulsive noise such as clicks, crackle and thumps. These distortions are frequently encountered on LP and 78 RPM records, but also occur in digital recordings due to drop-outs or distorted data packets. DeClick 2’s thump reduction works also effectively on vocal recordings with unwanted plosives. The algorithm has been improved in version 2 and is now less prone to reducing attacks and transients in the wanted signal.
• DeClip 2 restores audio recordings distorted by analog or digital clipping with an improved algorithm.

New in Version 2

All four plug-ins have received major improvements both in the processing algorithms and the user interface compared to version 1. DeNoise 2 introduces the novel dynamic noise profiles that help reducing noise that varies randomly over time, such as wind noise or rustle from lavalier microphones. Where the earlier versions merely captured a static noise print with time-constant noise levels, the dynamic noise profiles capture statistics from the noise to be reduced. The noise suppression algorithm then estimates the most suitable noise threshold curve for the noisy input signal using the measured statistics.

DeNoise 2, DeClick 2 and DeHum 2 now support Mid/Side (M/S) processing, which can reduce unwanted fluctuations in the stereo image. The core algorithm in DeClick 2 received major improvements and now better preserves transients and can be pushed to higher click and crackle sensitivities without introducing artifacts.

DeHum 2 has a new automatic fine-tune button that triggers automatic estimation of the hum noise frequency. The hum tracking and suppression have also been improved. DeClip 2 was improved in terms of audio quality and now offers even more impressive reconstruction of clipped signal peaks. All the plug-ins in the suite now support surround and immersive audio formats up to 7.1.6 channels.

Acon Digital Restoration Suite 2 is available as VST, VST3 or AAX for both Windows and Mac or as AU plug-ins for Mac. There are 32 and 64 bit versions for Windows and the Mac version is 64 bit.
