Waves X-Hum reduces rumble, DC-offset, and hum while preserving excellent
audio quality. X-Hum is part of the Waves Restoration bundle, which restores
vinyl records and damaged recordings. X-Hum and the other Restoration plug-ins
have a friendly interface that is easy to learn and use.
This user guide describes:
• the problems X-Hum solves;
• how to use the software;
• the software user interface.
WHAT PROBLEMS DOES X-HUM FIX?
X-Hum effectively reduces all three of these problems:
• Hum disturbance is usually caused by problematic ground-loop circuits.
Steady, low-frequency oscillation may occur in the recording, usually at a
sub frequency of the AC used in that country. For example, Europe uses
240 VAC so an ungrounded loop can cause a 60 Hz hum. The
fundamental disturbance can also cause harmonics at high enough
amplitudes to create additional problems.
• Low-frequency rumble is caused by mechanical analog systems, such as
turntables and tape machines; it is not steady in pitch.
• DC offset tilts in the audio waveform to one side of the zero baseline.

Hum, rumble, and DC-offset disturbances are usually stable throughout the
afflicted recording. For this reason, an EQ device is better suited for reducing the
problem than a dynamic process. X-Hum uses higher order filters with extremely
narrow cut notches than those found in a typical EQ. X-Hum’s notches can cut
up to 60 dB at very narrow bandwidths.

2. Using X-Hum
X- Hum is divided into two sections:
• A high-pass filter eliminates rumble and DC-offset.
• Eight notch filters linked in a harmonic frequency structure eliminate
steady-pitched hum.
Two parameters affect the high-pass filter:
• Slope can be set to –12 or –24 dB/octave.
• Frequency determines the filter cutoff frequency. Use a low cutoff
frequency (i.e., 10 Hz) to eliminate DC offset and preserve the signal’s
musically significant low-frequency content. Use a higher cutoff (i.e., 40–
80 Hz) to eliminate rumble.
The Harmonic Notch Filters section removes steady-pitched hum with different
harmonic structures built above the fundamental oscillation. There are three
parameters:
• The Frequency control sets the fundamental center frequency of the filter.
• The Global Q sets the width of the notch filters. For very steady-pitched
hum, use a narrow Q. If the hum’s frequency shifts throughout the
recording, use a wider Q.
• The Cut Gain of the notch filter can be set separately for each harmonic
filter.
Three link modes allow different methods of altering the gain of the filters:
• Linked: All filters are linked such that altering one filter adjusts all filters at
once while preserving their relative offsets.
• Odd/Even: Links the gain of filters 1,3,5,7, and 2,4,6,8 while preserving
the relative offsets within the odd and even groups.
• Unlinked: Filters are not linked; all filters can be adjusted independently.
NOTE: Relative offsets are preserved until a maximum or minimum value
is reached. Once a filter has reached its limit, further movement of the
other filters requires unlinking.
Although some phase distortion occurs in most digital and all analog EQs, these
devices do not use the extreme slopes and cuts found in X-Hum. Since phase
distortion increases with these more extreme settings, we recommend using X-
Hum as moderately as possible to satisfy your requirements.
