CARA (Computer Aided Room Acoustics) is a very advanced computer program for computing and optimizing Room Acoustics of arbitrary rooms. CARA is based on the sound source imaging method in combination with a back tracing procedure.

CARA analyzes and improves room acoustic influenced sound coloration in a two step procedure:
* determination of the basic acoustic properties of the room (Acoustic Ambiance) in combination with suggestions regarding the furnishings (wall materials, furniture) in order to linearize the reverberation time spectrum,
* automatic Positional Optimization for the loudspeakers and the listener to minimize sound wave interferences (standing waves) in the listening area.

De todas maneras yo me equivoqué con el software, yo me refería a otro que esta noche os diré.
