United States, and also contains harmonics of the fundamental noise frequency
located at even multiples of this frequency. By linking all the notch filter
frequencies to the  rst notch  lter band, cyclical noise can be quickly removed.
For example, a preset is provided that puts the notch-filter frequencies at
harmonic intervals to allow removal of mains hum and its harmonics (e.g. 60,
120, 180, 240, 300 Hz). However, if the noise contains unrelated cyclical noises
at various frequencies (e.g. 120, 168, 240, 328, 400 Hz), the NF575 notch  lters
can be linked at any frequency intervals to deal with camera shutter noise and
other such situations.
While the NF575 is really designed for noise removal, the notch  lters can
create some pretty drastic phasor-like e ects. Link all  ve notch  lters to the
 rst notch using the link control, select a wide Q setting, and then vary the
frequency control in the  rst notch  lter (band 1). The e ects are interesting,
and by automating the frequency control of the  rst notch  lter, the phasor
sweep can be made into a consistent effect during playback (instead of
locking to the rate of an LFO, which could produce di erent phasor e ects
during each playback pass).
FutzBox
The McDSP FutzBox plug-in is a set of audio processing tools for creating
distorted, low- delity versions of audio signals. The FutzBox can also mimic
the low-quality audio produced by radios, telephones, walkie-talkies, and
other devices.
Does your recording sound too sterile, too digital? A vintage-looking speaker
from the FutzBox Synthetic Impulse Model (SIM) library can make your track
sound as though it were recorded a few decades ago! Are you working on a
dialog track that should sound as though it is being heard through a cheap
intercom speaker? FutzBox can solve your problem here as well!
The FutzBox has an excellent selection of presets, divided up according to
their suggested applications. The General selection includes presets that can
be used either with dialog or with music, while separate selections of presets
are provided for Voice, to suit dialog or vocals, and for Tunes, to suit music.
So, for example, there are several Tunes presets in a sub-category named
‘Vintage’ that add the distortion and warmth associated with older recording
equipment. In the Voice presets, sub-category Character, there are several
simulations of classic telephones, including my favourite preset, called ‘Let’s
Do Lunch’, that simulates the sound of an iPhone loudspeaker.
