I’m Josefina Rozenwasser Marín, a sound designer, composer, and researcher based in Barcelona.

My practice operates at the intersection of cinema, sound art, narrative audio, and embodied listening, and is driven by a sustained research into how sound affects the body — shaping perception, attention, intimacy, and emotional states over time.

​

Across film, installation, performance, and narrative audio, I work with sound not as a background element but as an active material: one that organizes listening, modulates presence, and influences how the body inhabits time and space. My exploration focuses on how layers of noise, silence, vibration, and voice act on the body, influencing emotional regulation, intimacy, and ways of being present.

​

Alongside my artistic practice, I’ve worked extensively in sound design and sound direction for film and audio-based projects, collaborating with filmmakers, studios, and cultural institutions such as Alba Sotorra, Erika Lust, MACBA, and CCCB. Several of these works have been screened and recognized at film festivals in Spain.

​

I also develop fiction and narrative audio as a form of cinema without images, and work with sound in sex-positive, educational, and wellbeing contexts, where listening becomes a tool for care, trust, and embodied exploration. Within this framework, I’m the Director and Co-Founder of Sexify, an ongoing project investigating the relationship between sound, sexuality, and the body through experimental, voice-led audio formats and experiences.

My current research expands toward installation and material exploration, where sound, body, and physical elements converge to create situations of listening rather than closed objects — environments designed to be inhabited rather than observed.

​

I work comfortably across artistic, cultural, and applied contexts, bringing a research-led, practice-driven approach to projects that require both conceptual depth and practical execution.
