Frequently Asked Questions

What Are the Benefits of Using A Noise Reduction VST?

Using noise reduction VSTs is an invaluable tool for any audio engineer, giving them the power to reduce or eliminate unwanted background noise from their recordings.

The technology uses sampling and signal processing techniques to identify, differentiate, and reduce unwanted sound frequencies that can be heard in recordings.

The results are a cleaner, more professional-sounding recording with a softer noise floor and less clutter.

This allows us to bring out a more robust bass line or pick up minute details previously drowned out by noise.

Noise reduction plugins also have the added benefit of reducing the time you need to process and clean up audio files, allowing you to finish our projects quickly and up to speed.

What Are the Most Popular Noise Reduction VSTs?

Popular VSTs include Waves NS1, iZotope RX 7 Elements, Sonnox Oxford Denoiser, iZotope Spectral De-Noise, Acon Digital DeNoise 2, Accusonus ERA Noise Remover, and Waves Z-Noise.

Each plugin is designed to help improve audio quality in different ways, giving producers a range of options to find the best fit for their production needs.

With advanced features such as dynamic noise shaping, frequency-based processing, adaptive level optimization, these plugins can reduce unwanted noise while preserving elements of the original signal you want to keep.

What Is Noise Reduction?

Noise reduction is an essential part of audio production. It involves using various methods and technologies to reduce unwanted sounds while preserving desired sounds.

This process can be applied in post-production sound editing or as a part of a mixing workflow. It can help remove background noise and make recordings clearer, which is essential for achieving great-sounding mixes.
Noise reduction can either subtract or attenuate background noise so that the desired sounds stand out more clearly.

Techniques vary depending on the desired application and end result; however, those looking to achieve crystal clear sound will find many solutions available through noise reduction in audio production.

When Should I Use Noise Reduction Plugins?

A noise reduction plugin can elevate your audio production and help make your recordings as professional as possible.

One of the best times to use a noise reduction plugin in audio production is when you’re recording or editing in a noisy environment.

For those who record music or podcast audio, this is especially important – it’s essential for getting clear, crisp sound without any external interference ruining the quality.

Noise reduction software can also be helpful when compressing multiple tracks and attempting to balance their sounds together.

Additionally, they are beneficial when trying to create subtler sounds from layered recordings.

Where Does Noise Reduction Go In A Signal Chain?

When it comes to getting the best audio, the location of noise reduction within the signal chain greatly affects the efficiency and effectiveness of the process.

It is best placed in two spots: before and after compression. Setting your noise reduction before compression helps minimize unwanted frequency peaks that can otherwise occur with compression.

Additionally, it is beneficial to put a second, less aggressive instance of noise reduction at the very end as a final filter for any remaining unwanted elements in your track.

Doing this ensures that your track is free from any harsh, undesired frequencies and sounds.

Should I Really Use A Noise Removal VST Plugin?

If you’re a person who records music frequently, a noise removal VST plugin can be a fantastic tool.

This type of plugin is designed to detect and filter out noises from your audio recordings, saving you time and hassle in the editing process.

It eliminates the need for manual tweaking or special techniques in order to rid your recording of background hum or unwanted rumbles, giving you pristine recordings with minimal effort.

Most popular recording digital audio workstation software packages come with some of these plugins pre-installed.

Whether it’s a professional recording or an amateur podcast, noise reduction VSTs are invaluable tools in any audio project.

These free plugins are all great free alternatives to paid plugins such as Waves Clarity VX, Izotope Spectral De-noise, Waves Z-Noise, Izotope Voice De-noise, Acon Digital Denoise, Antares Soundsoap, Sonnox Oxford Denoiser, and Accusonus Era Noise Remover.

I hope you found this list of the best noise-reduction plugins helpful.

Many of these plugins are great for post-production, for eliminating unwanted noise, unwanted hiss sounds, noisy analog equipment sounds, and hiss noise in general. They can be used for both vocal tracks and musical instruments.
