e-ploser
P
losives are bursts of low frequency energy in a signal which can cause compressors to sound
u
npleasant. They are most often caused by the breath of a singer standing too close to the microphone.
T
he Vocalstrip De-ploser detects these artefacts and lets you manage their level. The De-ploser’s controls
a
re very similar to those of the De-esser:
Switch the De-ploser on by clicking on the power button in its top left-hand corner. The blue indicator
between the controls ‘glows’ to show that it is working.
• Move the Amount knob to control how much plosive is removed.
• Move the Thresh (threshold) control to set the detection level, so that the De-ploser can distinguish between plosives
and normal low frequency sounds.
To listen only to what is being removed, press the Aud button. This can be particularly helpful in ensuring that the threshold
is correctly set.
Equaliser
Switch the EQ on by clicking on the power button in its top left-hand corner.
Three popular EQ types are provided to allow you to cut low frequencies, find and
attenuate resonances and shape the top end of the signal. Switch each band on by
clicking on the oblong switch above the band’s curve graphic.
The low cut filter operates in the range of 30Hz to 300Hz , with a slight boost
around its cut-off frequency.
The notch filter operates in the range 200Hz to 10kHz and offers 12dB of boost and 36dB of attenuation with a high
Q value.
The high band EQ offers 12dB of boost/attenuation over the range of 1kHz to 20kHz with a low Q value.
EQ Display
When any controls within the EQ section are moved, the display in the top right-hand quarter of the window becomes an EQ
graph:
- The white line across the graph shows the frequency response of the current EQ
settings.
- The brown shaded area represent the impact of each of the three EQ bands.
- A display of the signal’s frequency response is shown in green. The signal
displayed can be switched between the plug-in input and output and can be
switched off, all using the FFT buttons to the left of the graph.
EQ Tip: Finding and Attenuating a Resonance
A vocal recording may contain a resonant frequency caused by a number of factors, including bad mic placement,
room modes, or even unpleasant resonances caused by the singer’s skull!
These can be detected and reduced in the following way:
• Switch off the low cut filter and high band EQ
• Set the notch filter gain to between about +10dB
• Sweep the frequency slowly up range, listening out for ringing
• Once you have found the offending frequency, bring the gain down to a significant negative value
Another technique is to use the green frequency response line in the EQ graph and locate resonances visually.
