  Rinaldi Petrolli was born in 1994 in Porto Alegre, a city in the southernmost state of Brazil, Rio Grande do Sul. From a young age, Rinaldi nurtured a love for music and a curiosity about the intricacies of musical instruments. This interest led him to a two-year luthier apprenticeship at the age of fifteen. His passion for acoustics later found a formal channel when he earned a B.S. degree in Acoustic Engineering from the Federal University of Santa Maria in 2019.

While at university, Rinaldi delved into various specialized areas of acoustics, ranging from room and environmental acoustics to digital signal processing. He also sharpened his programming skills in MATLAB and Python, employing them for data measurement and analysis in his academic projects. During this time, he collaborated on PyTTa (Python in Technical Acoustics), an open-source library for acoustic measurement and analysis. His undergraduate research successfully developed a low-cost method for modeling tube amplifiers using machine learning and Long Short-Term Memory neural networks, enabling real-time emulation via a Python interface.

In 2018, Rinaldi joined the Walters-Storyk Design Group (WSDG), first as an intern and later as a full-time acoustical engineer. His work there spanned various domains of acoustical analysis and computational simulations. This experience led him to meet Peter D’Antonio, and together with PK Pandey and John Storyk, they formed REDI Acoustics, LLC. At REDI, Rinaldi continues to focus on research and development in acoustics, particularly on creating and refining computational tools for optimizing room acoustic parameters.

 Artur Zorzo was born in 1994 in Brasília, Brazil. In 2012, in an effort to make better recordings of his band, he completed a professional audio course and instantly fell in love with acoustics after a lecture on the subject. In 2018, he received a B.S in Acoustic Engineering from the Federal University of Santa Maria.

He published several papers while in university. Most of them in the areas of real-time audio signal processing and acoustic measurements. For his undergraduate thesis, he researched and developed an active noise control system for headphones using real-time adaptive digital filters. In 2018, for his internship, he worked on the geometrical and acoustical optimization of ambisonic microphones. 

From 2019 to the beginning of 2021 he worked at Devialet as a signal processing R&D engineer in the development of signal processing algorithms for active noise-canceling earbuds. A patent was filed based on his works on the Ear Active Matching (EAM) algorithm. The EAM system automatically tunes the signal of the music to the shape of an individual’s inner ear. In parallel to that, he worked on the acoustic implementation of MEMS microphones on the products. 

Thiago was born in 1996 in Araçatuba, a small city in the countryside of São Paulo state, Brazil. In 2014 he started attending an Acoustic Engineering course at the Federal University of Santa Maria, Brazil, and he is going to receive his B.S. degree by October 2020. Since he was 10 years old, Thiago started attending drums classes and playing at church, which he does until today. His love for music and his facilities with math calculations led him to join both things and attend the acoustic engineering course.

While at university, he studied subjects such as room acoustics, digital signal processing, electroacoustics, environmental acoustics, psychoacoustics, building acoustics, acoustic measurements, computer programming, and many more. His undergraduate thesis is about wind turbines, where he built a simple prototype and measured it, based on the IEC 61400-11 Standard. Also, he made measurements using the beamforming technic, to find noise points in the prototype.  

In January 2020 Thiago started his internship at WSDG and in June he joined the REDI Acoustics team, helping with NIRO simulations and reports, as well as helping the WSDG Highland office team with advanced models and Sabine and Eyring calculations. 

João Vitor born in 1993 in Frederico Westphalen, Brazil. From 2011 to 2013, he worked as a live mixing engineer at venues with local bands. This experience led him to the study of sound and acoustics, which led to a B.S. in Acoustic Engineering from the Federal University of Santa Maria (UFSM) in 2019.

João worked mainly with signal processing, audio acquisition, and playback systems during university. He was also part of Praxis Peoples Education, a group that provided preparatory courses to working-class and low-income students who wished to enter university.

In 2018, João and a few colleagues began the development of PyTTa (Python in Technical Acoustics) with the vision of providing a solid and easy-to-use Python framework for acoustic measurements and analysis. João became the head developer and main contributor. This development brought a great knowledge of programming skills, which became João's passion.

From 2019 to 2021, João worked as a substitute professor at UFSM for the Acoustical Engineering course, where he was the leading professor in Fundamentals of Acoustics, Electroacoustics, and Theory on Live Sound Systems. He also had a role as a co-professor in Psychoacoustics and Building Acoustics. After this intense work in academia, João became a developer, having worked at Dynamox and Vertesis, developing cloud and desktop software, until 2023, when João gladly joined the REDI Acoustics team.
