THE HEART OF L-ISA IMMERSIVE HYPERREAL SOUND
The L-ISA Processor is a hardware solution that is exclusively dedicated to spatial audio processing, providing state of the
art object-based mixing to the most demanding immersive audio productions.
Combining a powerful multi-core architecture with a compact form factor, the L-ISA Processor is the audio heart of each
L-ISA system. It offers spatial processing and room simulation for up to 96 audio objects based on speaker positioning
information and mixing parameters (pan, width, distance, elevation, aux send) and provides up to 64 audio outputs to
L?Acoustics ampli?ed controllers. The L-ISA Processor is remotely and uniquely controlled by the L-ISA Controller software.

SPATIAL PROCESSING
In an object-based mixing approach, the properties of each sound object are de?ned independently from the loudspeaker
layout – so the entire mix can be faithfully scaled from the studio to a wide variety of venue and system con?gurations.
The L-ISA Processor provides ?ve parameters to the mixing engineer for each sound object:

• PAN : controls horizontal location
• WIDTH : controls perceived size, frompoint source to panoramic
• DISTANCE : controls perceived proximity (and applies the appropriate reverberation algorithm)
• ELEVATION : controls vertical location
• AUX SEND : provides a classic postdistance auxiliary bus send

PATENT-PENDING OBJECT-BASED ROOM ENGINE
The L-ISA room engine, accessible via the DISTANCE mixing parameter, allows users to naturally re-create different room
acoustics within the same venue or show. Speci?cally designed for object-based audio and variable space con?gurations,
the engine uses multi-channel 3D processing to diffuse energy across many loudspeakers, eliminating audible electronic
processing.
