EWA TRĘBACZ is a Polish composer and media artist, currently living in Seattle, USA. She received her Ph.D. from the University of Washington, Center for Digital Arts and Experimental Media (DXARTS), where she studied computer music with Richard Karpen and Juan Pampin, and experimental video with Shawn Brixey.

Ewa Trębacz holds Master's degrees from the Academy of Music in Kraków (Poland), where she studied composition with Bogusław Schaeffer; and the Academy of Economics in Kraków (Department of Computer Sciences and Econometrics). She has also been collaborating with animation artists from the Kraków Academy of Fine Arts since 1998, creating music and sound design for short films.

Trębacz's works have been performed, recorded and broadcast around the world. She has been commissioned by music festivals, such as the Klangspuren Festival in Austria and the International Contemporary Music Festival "Warsaw Autumn" in Poland. In 2009, her work things lost things invisible for ambisonic space and orchestra, received a prestigious recommendation of the 56th UNESCO International Rostrum of Composers in Paris, which resulted in multiple radio broadcasts on four continents.

Her works range from purely instrumental solo, chamber, and symphonic compositions, to compositions with computer realized sound with live performance, to sound tracks for animated films, to experimental stereoscopic video.

Her current research is oriented towards experimental media, focusing on spatial aspects of the experience of a work of art, with a special focus on the two immersive techniques: ambisonics and stereoscopy. Her recent projects are based on the idea of the separation and manipulation of spatial cues, both visual and sonic, in order to design a game of illusions, to create a continuum between the synthetic and live sources, and to challenge the borders of perceptual limitations.
