How DeNoiser works
DeNoiser is based on spectral subtraction. Each section of the fre-
quency spectrum, that has an amplitude below the estimated noise 
floor, is reduced in intensity by use of a spectral expander. The result 
is a noise reduction that does not affect the phase of the signal. 
The figure below shows the signal flow:
The solid line represents the actual audio signal, while the dotted lines represent 
control signals.
The signal is continuously...

The Noisefloor Display
The display to the left in the DeNoiser window is crucial when making 
settings. It contains the following three elements:
•The dark green spectral graph.
This shows the spectrum of the audio currently being played back. The horizontal axis 
shows the frequency (linear scale). The low frequencies are visible on the left side, the 
high ones on the right side. The vertical axis shows the signal amplitudes, thus the level 
(displayed as a...

Using the A/B setups
With the A/B buttons you can make instantaneous switches between 
two different DeNoiser setups, allowing you to quickly try out and 
compare different configurations. You can also use this feature for 
separate settings for two different sections of an audio recording. 
Proceed as follows:
1.Make the settings you want for setup A.
2.Click on [Store] and then on the [A] button.
3.Make the settings you want for setup B.
4.Click on [Store] and...

Grungelizer
The Grungelizer adds noise and static to your recordings – kind of like 
listening to a radio with bad reception, or a worn and scratched vinyl 
record. The available parameters are as follows:
Parameter Description
Crackle This adds crackle to create that old vinyl record sound. The farther to 
the right you turn the dial, the more crackle is added.
RPM switch When emulating the sound of a vinyl record, this switch lets you set the 
RPM (revolutions...

Reverb plug-ins
This section contains descriptions of the plug-ins in the “Reverb” 
category.
Reverb A
Reverb A is a reverb plug-in which provides smooth, dense reverb 
effects. Reverb A has the following parameters:
Parameter Description
Mix Sets the level balance between the dry signal and the effect (wet). If 
Reverb A is used as a send effect, this should be set to maximum wet, 
as you can control the dry/wet balance with the send. 
Room Size This setting...

Reverb B
The Reverb B provides reverb with low processor demands. It has the 
following parameters:
Parameter Description
Mix Sets the level balance between the dry signal and the effect. If Reverb B 
is used as a send effect, this should be set to maximum as you can con-
trol the dry/effect balance with the send.
Room Size Governs the “size” of the simulated room environment.
Predelay This parameter sets a delay between the direct sound and the reverb 
effect...

RoomWorks
RoomWorks is a highly adjustable reverb plug-in for creating realistic 
room ambience and reverb effects in stereo and surround formats. The 
CPU usage is adjustable to fit the needs of any system. From short 
room reflections to cavern-sized reverb, this plug-in delivers high qual-
ity reverberation. RoomWorks has the following parameters:
Parameter Description
High Freq Frequency at which the high shelving filter takes effect. Both the 
high and low...

Width This controls the width of the stereo image. At 100%, you get full 
stereo reverb. At 0%, the reverb is all in mono.
Efficiency This unique control determines how much of the CPU is used for 
RoomWorks. The lower the percentage of efficiency, the more 
CPU resources will be used. This will yield a higher quality reverb 
than higher percentage settings. Interesting effects can be cre-
ated with very high Efficiency settings (>90%). Experiment for...

Envelope Attack The envelope settings in RoomWorks control how the reverb will 
follow the dynamics of the input signal in a fashion similar to a 
noise gate or downward expander. Attack determines how long 
in milliseconds it takes for the reverb to reach full volume after a 
signal peak. This is similar to a predelay but the reverb is ramping 
up instead of starting all at once.
Envelope Release The release determines how long after a signal peak the reverb...

Surround plug-ins
This section describes the plug-ins in the “Surround” category.
Matrix Decoder
The Matrix Decoder reverses the Encoder process performed by the 
Matrix Encoder (see above). It is used for monitoring how an encoded 
mix will sound when played back on a Pro Logic compatible system. 
When an encoded mix is played back via the decoder, the Lt/Rt chan-
nels are again converted to four outputs (LRCS).
This manual does not attempt to explain the full...
