Reverb plug-ins
This section contains descriptions of the plug-ins in the 
“Reverb” category.
RoomWorks
RoomWorks is a highly adjustable reverb plug-in for creat-
ing 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 quality re-
verberation. RoomWorks has the following parameters:

ÖNote that the options in the Surround section on the far 
right of the RoomWorks panel are available only when us-
ing the plug-in as an insert for a surround-enabled track.
RoomWorks SE
RoomWorks SE is a “lite” version of the RoomWorks re-
verb plug-in. This plug-in delivers high quality reverberation, 
but has fewer parameters and is less CPU demanding than 
the full version. RoomWorks SE has the following parame-
ters:

Spatial plug-ins
This section contains descriptions of the plug-ins in the 
“Spatial” category.
MonoToStereo
This effect will turn a mono signal into a “pseudo-stereo” 
signal. The plug-in must be inserted on a stereo track 
playing a mono file to work.
The parameters are as follows:
StereoEnhancer
This plug-in will expand the stereo width of (stereo) audio 
material. It cannot be used with mono files.
The parameters are as follows:

Surround plug-ins 
This section describes the plug-ins in the “Surround” cat-
egory.
Matrix Decoder
The Matrix Decoder reverses the Encoder process per-
formed 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 en-
coded mix is played back via the decoder, the Lt/Rt chan-
nels are again converted to four outputs (LRCS).
Setting up

6.Connect a master recording device to the stereo mix 
output and perform a mixdown as usual.
The resulting encoded stereo mix will now be compatible with common 
home systems that use the Pro Logic standard.
Using the Matrix Encoder with the 5.0 surround format
There are situations when you may want to mix for several 
Surround formats. For example, you might need to mix the 
same material for 5.1 and one for LRCS.
5.1 is similar to LRCS. Omitting the LFE channel is easy,...

Mix6To2 
The Mix6To2 effect allows you to control the levels of up to 
six surround channels, and to mix these down to a stereo 
output. The pop-up menu contains a number of speaker ar-
rangement presets that correspond to some default sur-
round formats. The Mix6To2 lets you quickly mix down your 
surround mix format to stereo, and to include parts of the 
surround channels in the resulting mix.
Note that Mix6To2 does not simulate a surround mix or 
add any...

Mixconvert
The Mixconvert plug-in is similar to the Mix6To2 plug-in in 
that it is used to quickly convert a multichannel mix into 
another format that uses less channels when used as in-
sert (for example converting a 5.1 surround mix to a stereo 
mix). Mixconvert can convert surround mixes into other 
surround formats such as mixing a 7.1 Cinema surround 
format down to a 5.1 home theater format.
There are several obvious applications for this:
 Auditioning what an...

Interface
Overview
The plug-in’s interface has three different sections. On the 
left you find the input Configuration display with all para-
meters that directly affect the input configuration. In the 
middle section the level parameters for the upmix/down-
mix are displayed. Above this, the preset controls can be 
found. On the right the output configuration is displayed 
with all parameters that affect the output configuration. 
Additionally, on the far left there is a...

Phase shift
You can shift the phase of the front left/right channels and 
the surround left/right channels in steps of 90°. Clicking 
the button once will increase the phase by a further 90°. 
You can reset the phase value by right-clicking (Win-
dows) or [Ctrl]-clicking (Mac) on the button.
Phase shifting can be used for various purposes. In a 
downmix from 2 channels to 1 channel it may be useful to 
introduce a 90° phase shift on one channel to avoid level 
increases in...

General Notes
Level
The volume of the downmixed signal can be different from 
the volume of the original mix. There are several reasons for 
this:
 The input signals must be scaled to avoid clipping.
 The number of speakers used influences the overall volume.
 The level of the downmixed signal depends on the correlation 
of all added signals, which is why phase shifting can influence 
the volume level.
LFE channel
The LFE channel is automatically filtered using a low-pass...
