The Oxford DeClicker features three discrete sections for removing pops, clicks and crackle from your sound. 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. Download Declicker Software Acoustica v.4.0 Acoustica makes it easy to record, edit and process audio on your PC. You can open or save files in different formats including wav, wma, ogg, mp3 and more. 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.

Terms & conditions apply Ideal for restoring vintage vinyl and shellac records, X-Click removes strong transient noise like clicks, spikes, switching noise, and digital crosstalk while preserving the sonic integrity of your source material. The Declicker is useful for restoring for old vinyl and other recordings that cause clicks, pops and/or crackles. The Declicker can also remove a variety of short noises from other sources, including lip clicks and 'smacking' on vocals, some clicks caused by digital errors or electrical interference. The Declicker works best on click-transients.

If you deal with sound recordings on a daily basis, you are probably keen on the numerous issues that can come along with making them sound good. Whether the sound was recorded by a professional recordist or a complete novice, sometimes there are anomalies and noise problems that you simply can’t get away from, even if you follow all the rules to getting great sound on set.

Noise reduction software is your saving grace. There are a few really solid tools out there, some you’ve certainly heard of, and others you may not have. Let’s break down some of your best options.

Accusonus ERA (N/R/D) – Noise Reduction Magic

Accusonus is one of those companies that has gone largely unheard of in respects to audio repair, which is a shame as their offerings are affordable, easy to use, and capable of producing quick results. Here’s a quick overview of their comprehensive ERA Bundles. The ERA Bundle Standard ($149) contains 4 single-knob plugins, each one solving a different audio problem:

● ERA Noise Remover
● ERA Reverb Remover
● ERA Plosive Remover
● ERA De-Esser

Declicker Vst Plugins

The Accusonus ERA Bundle Pro ($499) contains the 4 single-knob plugins as well as ERA D, a joint noise & reverb reduction plugin for post professionals.

You may be wondering about the steep upgrade when ERA-D does essentially the same things as the ERA Noise Remover and the ERA Reverb Remover. The secret here is that ERA-D does something that other tools don’t: 2-channel intelligent noise reduction. This means you can feed in 2 different channels (boom and lav, for instance) and the 2 channels will inform each other of the content, making for a much cleaner denoising process with fewer artifacts. If this fits your situation, I’d say it’s worth the small splurge for the top tier version.

The benefits of Accusonus’ tools is that you can run them in real-time and get results quick. The one-knob style functionality makes them extremely simple for non-audio geniuses to use. It’s definitely worth it for video editors, indie filmmakers or audio engineers who need a clean and quick solution.

The advanced version will cost you a pretty penny, but if you can afford the standard version, you still get most of the available tools, minus just a few awesome ones.

Adobe Audition CC – The Editor’s Go-To Sound Tool

Many video editors will be quite familiar with Audition, as it comes bundled with the Creative Cloud suite (meaning many of you already have this available to you without spending an additional dime).

Audition is not just a noise reduction software, but a complete digital audio workstation, capable of multi-track editing, mixing, sound design, mastering and spectral audio editing. While the noise-reduction tools are relatively bare-bones compared to some other options, it likely has the tools you need the most:

Click Removal
Pop Removal
Hum Removal
Sound Removal (for odd, random sounds)
Adaptive Noise Reduction (for constantly changing sounds, like an airplane fly-by)
Hiss Removal
Volume Leveling
Pitch Correction
Plus the entire suite of tools and plugins that Audition has to offer

These tools, along with their spectral editor (complete with photoshop-like selection tools), give you the ability to clean out most common sonic problems.

If you are a Premiere Pro editor on a budget, this is a no-brainer. Learn to use Audition as well as you do Premiere or After Effects, and you are golden. If you don’t have the Adobe CC suite, but you want Audition, it’ll cost you $20.99 per month.

Cedar Studio – Serious Audio Restoration

Cedar is the grandfather of noise-reduction, the first major competitor in the industry, and what most of the professionals use when lives are on the line, like in the case of forensic investigations.

Cedar’s tools are available in both software and hardware, with different tools for different purposes, such as live event noise-reduction where a zero-error and zero-latency solution is absolutely necessary, or in server setups where huge bulk processing must happen 100x faster than real-time to keep up with the huge amount of audio that needs to be processed.

But most studio professionals on this level would rely on Cedar
