Tailoring the product to the users’ needs

Different users meaning different needs, LEA 2017 presents a simplified offer with 4 options.  Users working with the Standard Module of LEA, dedicated to acoustics analysis, with recording, analysis, sound design by drawing into the Time-Frequency image of the signal, and reporting capabilities, can now complete their software with one or several of four modules depending on their needs:

  •  PSYCHO, dedicated to the analysis of the sound perception
  •  3D TRANS, for the perfect 3D sound rendering
  •  ORDERS, dedicated to order analysis and harmonics detection
  •  XTRACT, for the denoising and automatic sound separation

Easing sound design with new ergonomics

LEA lets users focus on the sound design, not on how to use the software. The goal is to help LEA users work smarter and get software usability questions off their mind, with a more intuitive interface, fewer picks and clicks and an increased flexibility. LEA’s interface now proposes a simplified and user-friendly version of the software, saving time in the realization of any sound project. Stéphane Molla, LEA Product Manager for OPTIS, says:


With its new intuitive design, LEA is now easier to use to study design sound in any industry.

Accelerating processes

Among the important enhancements brought by LEA 2017 is the faster performance of the software within 64 bits environments. Stéphane Molla says:


Now developed for 64 bits systems only, LEA’s leads to more accurate calculations, adding the ability to open larger files than before

Most LEA features have been enriched, resulting in shorter load times, and a wider choice in terms of export formats of data. LEA thus speeds up the design and analysis processes, and helps reduce time and effort to achieve the desired sound result. The company has also worked on optimizing sound reproduction in 3 dimensions, to better meet the needs of its users, and current playback capabilities. The Head of Acoustics and Vibration dept. at Valeo says:


It takes me 2 minutes to do something that used to take half an hour.

Reviewing acoustics towards Sound Design in Virtual Reality

OPTIS GENESIS now connects LEA to its Virtual Reality solutions, to facilitate advanced sound analysis. Embedding sounds in a scene and adapting them to a product, OPTIS Virtual Reality solutions take collaboration around the sound review to the next level. OPTIS GENESIS customers can now experience their sound designs in collaborative virtual environments, to understand how their end-users will react to various sounds and if sounds match – or not – with products. The ultimate goal is to help them make comprehensive choices in terms of acoustics, to make them able to deliver products whose sound quality matches the global quality to market.

Stéphane Molla concludes:


LEA 2017 saves time, improves your sound analysis and explores new horizons in terms of acoustics and sound perception in a more user-friendly way, thanks to many features’ improvements.
