X-Hum

X-Hum from Waves is a specialised cleanup tool for producers dealing with low-frequency noise. It targets hum, rumble, and DC offset that can eat into your headroom and muddy your bass. Eight tuned notch filters work on 50 Hz and 60 Hz hum and their harmonics, reducing them by up to -60 dB, while a high-pass filter (12 or 24 dB/octave) removes rumble. You can link or unlink filter parameters for quick setup, and factory presets cover common scenarios. Use it on tracks recorded near transformers, with ground loops, or from mechanical vibration. It operates with zero latency and minimal CPU load, making it suitable for mixing and mastering. Ideal for home studio producers using FL Studio, Ableton, or Logic who want cleaner low end without complex routing.
