Sound and Vibration

LEA: the Sound Lab for the Industry

The signal analysis, sound design and psychoacoustics software package for acousticians. 

Boost your sound design with a time-frequency sculpting tool. LEA’s graphic representations provide you with simple but powerful tools for altering sound characteristics with just a click.

A full suite of analysis tools…LEA is built with ground-breaking algorithms developed in partnership with the CNRS (French National Centre for Scientific Research). It is the leading tool for analysis of physical sound characteristics.

… focusing on auditory perception. With LEA, play back the sound you are working on in 3D, at any stage in the process, and calculate its psychoacoustic parameters.

The gate to unique applications. LEA gives access to 2 major automobile oriented software packages:

ASD Designer: to design engine sound and generate additional sound using the audio system of the vehicle

geneCARS: interactive sound simulator for Driving Simulators, for human factor studies as well as NVH purposes
