After a three-year training course in sound engineering, Aria De La Celle joined Ircam as a sound assistant, enabling her to deepen her knowledge of sound engineering and open up to new artistic and technological horizons. This collaboration proved decisive in her career, and she continues to work regularly on sound engineering projects.
She quickly opened up to live performance, where her knowledge of mixed music enabled her to try her hand at sound design, working alongside Volmir Cordeiro, Marine Colard, Michel Cerda, Muriel Coulin, Martine Pisani, Lena Paugam and Bryan Campbell.

She also composes electronic music under the nameAria Seashell, and is involved in various techno projects, notably the duo Baguettes for Faguettes.

The blending of influences from techno and mixed music plays an important role in her work as a sound designer. She also questions the relationship between sound and the stage, exploring the transformation of sound materials and the relationship between space and time.

His interest in contemporary music and new musical forms has also led him to work for the Lucerne Festival Academy, the Ensemble Intercontemporain, composers such as Benjamin Dupé, and on various mixed-music projects.

She also performed in the creations of Lascaux and Seeing Lascaux again by Gaëlle Bourges.
