About Re-Compose

The History of Re-Compose

Starting in 2007, Re-Compose has been developing pioneering methods and technologies for digital music production and optimal music perception. Re-Compose software makes music fully adaptive, where all elements of a music composition can be recomposed or rearranged in real time through sensor or human input. This leads to the development of intelligent tools for music composers and producers that help them get new and complex musical ideas (i.e. melodies, chords and harmony, accompaniments, rhythm patterns, etc.), deliver these ideas fast, and optimize the impact of music.

Re-Compose is currently based in Vienna, Austria.

The People of Re-Compose

Portrait Stefan Oertl

Dr. Stefan M. Oertl

CEO and Development

Stefan is the founder of Re-Compose. He holds a doctorate of natural sciences in psychology from the Vienna University (music psychology and cognition) and a MSc in Computer Graphics and Animation from the Vienna University of Technology.

In addition to his traditional education in classical piano and harpsichord, he completed the film scoring program at the University of Southern California's prestigious Thornton School of Music in Los Angeles. Among his media-related productions is the sound concept (sound design and ambient music design) for the documentary “Shadowing the Third Man”. The film premiered at the Cannes Film Festival in 2005 as one of the festival’s official selection and was awarded the overall first prize at the Festival di Palazzo Venezia Arte in 2006.

During his scientific and creative career (in ongoing associations with universities), he has been professionally analyzing the structures and mechanics of highly effective music, with a focus on commercial productions and technical applications. His key interests lie in the psychological mechanics of trance, psytrance, and techno leading to altered states of awareness and an "optimal experience", as well as the general evolution of mainstream music.

Portrait Gerrit Wunder

Gerrit Wunder

Film Music Composer

Gerrit studied classical composition, jazz composition, and film music at the University of Music in Vienna. As a freelance and prize-winning film and TV composer, he writes and produces for major European and American film productions, TV stations, and commercials.

He is one of the very few composers in the world who consecutively won both the prestigious ASCAP Competition and BMI Award for Aspiring Film Composers in Los Angeles. As a result, he was asked to work with Mike Post on the US hit series "Law and Order". Post, considered the most successful composer in television history, refers to Wunder as having "that special gift of writing music in a way that places him a cut above the rest in the field."

Gerrit currently resides in Los Angeles, California. After working on music for the documentary "Na Naia - Legend of the Dolphins" featuring stars such as Kate Winslet, Daryl Hannah and Megan Fox, he is currently working on different international movie trailer and TV projects.
