What Waves X-Hum Is For
Waves X-Hum is an audio restoration plugin designed to remove low-end spectrum issues that immediately ruin a recording or mix: 50/60 Hz hum, buzzes, mechanical vibrations, as well as DC offset (direct current component) which can reduce available dynamic range. It is aimed at sound engineers, musicians, podcasters, and broadcast technicians who want to quickly secure a source (voice, bass, DI guitar, synths, field recordings, interviews) and recover clearer low-mids, tighter bass, and a more manageable output level.
Main Features
50/60 Hz Hum and Harmonics Removal
X-Hum works with both 50 Hz and 60 Hz powered environments. Its processing core relies on 8 tuned notch filters capable of reducing hum and its harmonics by up to -60 dB. The result: you eliminate buzz caused by ground loops, faulty cables, power supplies, nearby transformers, or unstable connections, while preserving the useful energy of the signal.
Rumble Control with Musical High-Pass Filter
For unwanted vibrations and rumbles (mic stand, ventilation, mechanics, handling, stage), X-Hum offers a high-pass filter selectable with a slope of 12 dB/octave or 24 dB/octave. This approach cleans the low end without making the source thin, by precisely adjusting the cutoff according to the instrument or voice.
DC Offset Management to Recover Headroom
At sub-audible frequencies, a DC offset can reduce your headroom and complicate dynamics, especially during tight gain staging. X-Hum allows you to adjust the cutoff to remove this direct current component while preserving the bass, facilitating level optimization and signal stability in a processing chain.
A Simple, Fast, and Flexible Workflow
Factory presets cover the most common scenarios and speed up troubleshooting during sessions. You can also link filters to adjust multiple parameters simultaneously, or conversely unlink them for surgical intervention. With its zero latency and minimal CPU consumption, X-Hum naturally integrates into mixing, editing, and restoration workflows, including real-time processing.

Questions frequently asked
Does Waves X-Hum remove 50 Hz mains hum?
The 8 tuned notch filters reduce 50 Hz or 60 Hz hum and its harmonics by up to -60 dB. This processing specifically targets ground loops, power supplies, and faulty cables.
How to remove vibrations and rumble from a vocal input?
A high-pass filter with selectable slope of 12 dB/octave or 24 dB/octave allows attenuation of mechanical vibrations, ventilation noise, or handling sounds. The cutoff frequency can be adjusted according to the source.
Does the plugin handle DC offset without cutting bass frequencies?
The cutoff setting removes the sub-audible DC component to recover headroom. Bass frequencies are preserved during this processing, facilitating gain staging.
Is X-Hum usable in real-time during a mixing session?
Thanks to its zero latency and minimal CPU usage, the processing can be inserted in a mixing, editing, or restoration workflow in real time.
What are the Mac and Windows compatibility requirements for Waves X-Hum?
On Mac, compatibility covers macOS Catalina 10.15 through Sonoma 14, with Intel processors or Silicon architecture and 8 GB of RAM. On Windows, Windows 10 64-bit and Windows 11 are supported with Intel or AMD x64 processors and 8 GB of RAM. The software is available as a download.
