Waves Z-Noise released

Waves set the standard for professional audio restoration with our acclaimed X-Noise plug-in. Now we’ve raised the bar. Waves is taking noise reduction to a whole new level.

Brand new proprietary algorithm

Accurate dynamic noise profiling

Better low frequency resolution

Advanced transient preservation

The Z-Noise Difference

Other noise reduction methods need you to provide a section of pure noise in order to deliver optimal results. Z-Noise features an exclusive Extract mode which can create a noise profile from sources that contain signal, as well as a flexible Adaptive mode. This innovative dynamic noise profiling delivers unparalleled results when reducing noise that changes over time.

What’s more, other noise reduction systems are limited by the restrictions of traditional FFT band split methods, which divide the frequency range linearly into equally spaced bands. This leads to excessive frequency resolution in the high end, and insufficient frequency resolution in the lower end of the spectrum. And in the time domain, it results in insufficient time resolution for high frequencies and excessive time resolution for low frequencies. These inherent limitations lead to smeared audio images that lack crispness and clarity. Z-Noise changes all that.

Z-Noise employs a brand new “more musical” algorithm which delivers better low-frequency resolution and improved time sensitivity. Combined with its advanced adjustable transient enhancement, Z-Noise lets you remove noise while retaining all the power and punch of your source recordings. The result: Better noise reduction and better transient preservation.

Bring On Z-Noise

Ideal for background noise such as tape hiss, ground hum, and computer noise, Z-Noise is a true broadband processor which can eliminate high-frequency hiss and low-frequency rumble simultaneously, while preserving the sonic integrity of your source.

Z-Noise gives you the power to shape your noise profile with pinpoint accuracy, using a familiar 5-band EQ interface. Real-time operation means you can fine tune parameters and hear your changes as you make them. You can monitor the entire Audio output or just hear the Noise being removed. Z-Noise even lets you choose between increased frequency resolution or improved time resolution, or a combination of the two.

Bottom line: With its extensive noise profile shaping tools, innovative transient preservation and exclusive extractive/adaptive dynamic noise detection, Z-Noise truly is a revolution in noise reduction.

Z-Noise Controls

Analyzer displays the Input signal in Red, the Noise profile in White, Output signal in Green, and the EQ profile in Orange.

Noise Profile EQ offers 5 Band On/Off, Band Type, Frequency, Gain, and Q controls to shape your noise profile.

Threshold determines the level below which the noise profile is cleaned, while the level above the profile is unchanged or processed minimally.

Reduction defines the amount of noise reduction applied to the signal below the Threshold.

NR The Noise Reduction meter displays the amount of noise being removed.

Release sets the time it will take for noise reduction or gain attenuation to occur.

Attack is the time it takes for attenuation to stop or for the gain to rise.

Transient preserves transients by enhancing them before the noise reduction process takes place.

Knee adjusts the sharpness of the gain reduction curve below the noise profile.

Learn Use it to create a noise profile when you have a sample of pure noise.

Extract creates a noise profile from sections that have mixed signal and noise.

Adaptive scans your track in real-time and creates a noise profile on the fly.

Smooth sets the highest frequency resolution.

Punch delivers the best time resolution, perfect for recordings with significant attacks and transients, like percussive sounds or plucked strings.

Norm offers a balance between frequency and time resolutions.

Output lets you choose between Audio (the audio after Z-Noise processing) and Difference (the noise being removed).
