Room
The Room algorithm was introduced in the PCM96 and is one of the most flexible algorithms
we’ve ever invented. Reflection patterns can be easily selected, scaled and equalized all while
simultaneously passing audio, and the room size can be instantly changed or reversed. It is
similar to other Lexicon
®
reverbs in that it is used to create the illusion of space. However it
differs in important ways. A room is comprised of a selectable early impulse taken from actual
room measurements. There are several categories of responses, including small rooms, large
rooms and odd rooms (impulses from unconventional sources). There are parameters to allow
adjustments to this response, including scaling and reversing the response. In many cases this
is sufficient.
There are three primary applications for the Room algorithm:
• Post Production: Lexicon
®
reverbs are renowned for smooth tails and controlled frequency
response. However, in many cases the earlier components are more important. This may be
true for some forms of popular music and is even more true for post-production. In these
cases, specific types of spaces need to be invoked for convincing dialog and effects.
• Reverbs:
This algorithm can also be used to generate large reverberant spaces that have a
very different character from the more traditional Lexicon reverbs. These reverbs provide a
high-quality counterpoint to the original “Lexicon Sound”. There are a number of presets
which take advantage of this.
• Effects:
Because room patterns can be reversed, there are many additional sounds available,
such as backwards reverb and gated sounds.
The Room algorithm provides the inherent realism of the actual space with all the precise
control and manipulation that is only possible with a reverb synthesizer.

Though the term “impulse” is used in this manual, these algorithms are NOT
convolution reverbs!
