CHAPTER 2 
Introducing JVP
 
This chapter introduces you to JVP. Topics covered are basic concepts in com-
pression, expansion, gating, de-essing, parametric equalization, and delay
effects. Also covered are JVPÕs basic architecture and user interface.
JVP is designed to be used in any editing, sweetening, or mastering application.
Since it incorporates four of the most useful digital signal processes into one tool,
you will probably use it more than any other DSP plug-in...

pressed vocal track is added to a typical pop mix, certain loudly sung
words or syllables would be very obtrusive, while quieter phrases would be
buried underneath the instrumental texture. This is because the difference
between the loudest and softest sounds in the vocal, its dynamic range, is
very large. This same problem occurs for any instrument which had a
dynamic range larger than the music bed into which it is being mixed. 
By using a compressor to...

(reduced in level) while those softer than the threshold are unchanged.
As the input signal exceeds the threshold, gain reduction (reduction in loudness) is
applied. The amount of gain reduction that is applied depends on the compression
ratio. The higher the compression ratio, the more gain reduction is applied to the sig-
nal.
The graph shows the relationship between compression ratio and gain reduction.
Examine the 2 to 1 ratio curve. For signals above the...

As the input signal drops below the threshold, its output level drops at twice the
rate it would using a 1 to 1 ratio. In effect, sounds below the expander threshold
are Òfaded outÓ more quickly than they would be normally. This effect can be
exaggerated into what is normally called a gate. 
When expanders have ratios higher than 1 to 10, sounds below the threshold are
faded out very rapidly. This effect is called gating and can sound very abrupt.
Adjusting the gate...

JVP UserÕs Manual17 Understanding Compression
Using this setting, sounds above the compressor threshold will be com-
pressed at a 4 to 1 ratio. Sounds below the compressor threshold but above
the gate threshold will not be changed. Sounds below the gate threshold
will be gated out completely. 
Used on a vocal track, this setting will compress only hot peaks in the voice,
while gating out the room sounds, mike stand sounds, and breath noises in
the track. Precisely what gets compressed and gated is a...

pression or expansion ratios have high values, the abrupt change can be
heard and often sounds artiÞcial.
To make it possible to create settings where the dynamic effects are more
natural sounding, JVP incorporates a Knee control which allows you to
soften the transition between sections of the gain curve. The graph below
shows a curve which has Òsoft kneesÓ, making the dynamic transitions
more subtle.
The details of operating the compressor Õs Knee Control are...

of instruments. The illustration below shows the effect of changing the
attack time.
The release time of a compressor is the time it takes for the gain to return to
normal after the input level drops below the threshold. Setting too quick a
release time can cause undesirable artifacts in the output. If the release time
is too long, the compressor will not accurately track level changes in the
input. The illustration below shows the effect of changing the...

What Is A De-Esser?
When recording spoken or sung material, the sibilants (Ss, Ts, CHs, and
SHs) in the track often sound louder than the rest of the signal. The effect is
unnatural and often irritating. The problem of an abnormally accentuated
frequency range can also be encountered in a complete mix as well. The
solution to this problem is to compress only the sibilants, thereby lowering
their level relative to the rest of the track. Processing a signal this way is...
