Timeframe: 2019–ongoing

[ freq:res ] is a long-term research and performance project investigating how sound influences visual form. Structured around data, improvisation, and audiovisual systems, the study draws on sound’s inherent structure, frequency, rhythm, amplitude, as a catalyst for real-time visual transformation.

This modular, improvisation-based practice spans audiovisual performance/installation, and collaborative experimentation. [ freq:res ] approaches frequency as architecture, vibration as composition, and listening as a creative methodology.

In projects and Collaborations:

• Pitch Shifting (2019–ongoing)
  A long-standing audiovisual collaboration between Sanja Star and Grgur Savić, rooted in live improvisation and cross-disciplinary performance that merges electroacoustic sound with dynamic visuals. Their work thrives on dialogue, between acoustic and electronic, structure and spontaneity, creating ever-evolving performances through live improvisation. Expanding beyond the duo, Pitch Shifting collaborates with artists across disciplines.

• OUTBOX: A Sonic Journey through Interaction and Visualization (2023–ongoing)
  An improvisational performance by Grgur Savić and Sanja Star that transforms the "urban white box" into a contemplative audiovisual laboratory, where amplified objects, generative sound, and live visuals blur the boundaries between media and perception.

• Seas of Mintaka: Navigating the Cosmic Soundscape (2024)
  Inspired by the star Mintaka, this cosmic AV journey by Savić and Star charts sonic constellations and abstract visual terrains, merging experimental music and real-time digital animation into an immersive meditation on exploration, frequency, and the vast unknown.

• INFILTRATION – A Sonic and Visual Exploration of the Unknown (2024–ongoing)
  A dark, sensory performance where digitally transformed saxophone textures and reactive 3D visuals unfold in shifting perceptual space, exploring themes of presence, intrusion, and the liminal forces that shape experience.

• {mapping spacetime} series (2024–ongoing)
  A series of improvised public performances using projection mapping and sound art to explore the fluidity of time-space and energy through unscripted audiovisual interventions.

• A Sound & Light Conversation (2024–ongoing)
  An immersive AV performance by Katharina Bévand and Sanja Star, where modular synthesis and audio-reactive visuals unfold in real time as an evolving dialogue between sound, light, and memory.

• Pip pip, aio oia – Past is present and present is past, all is one and one is all (2023)
  A week-long interdisciplinary Fluxus project blending live projections, improvised music, movement, and urban flash mobs into a recursive film-performance that reimagines ephemeral artistic moments through layered documentation. Participating artists: Birgit Wieger, Wolfgang Schliemann, Ulrich Phillipp, Silvia Sauer, Ulrike Schwarz, Ingo Deul, Mareike Buchmann and Sanja Star.

• Visual Music and Sonic Shadows / Scott–Star (2023–ongoing)
  A hybrid audiovisual project with modular synthesist Richard Scott, combining live improvisation and cinematic abstraction, where digital animation, shadow play, and urban footage converge in a feedback loop between performance and art film.

• Salvo–Odabaşi–Star (2025–ongoing)
  A noise–ambient collaboration in which live visuals interact dynamically with unpredictable sonic textures, creating generative feedback loops between light, abstraction, and chaotic structure.

• Chats en Colère series (2023)
  A FLINTA*-focused evening of experimental sound and voice, where Sanja Star’s evocative visuals complemented the performances of Vivienne Griffin, Zweatlana, and Maike Messer through immersive digital atmospheres. The event also featured a live audiovisual collaboration in which Ana Bogner’s poetic sonic landscapes were visually extended by Sanja Star’s generative projections, evoking utopian, dreamlike spatial narratives.

• PingPengPerformances – PAPER fLUX (2023–ongoing)
  A four-woman improvisation quartet integrating sound, movement, and new media in a ping-pong-inspired performance structure, grounded in risk-taking, object play, and real-time audiovisual exchange.

Included Artworks:

• Lux‑O (organic): Frequencies of an Alien Perspective (2024)
  An experimental art film that juxtaposes black-and-white footage of organic environments with digital abstractions and Mars mission sounds to explore unseen vibrational forces and extraterrestrial resonance within the natural world.

• to see the unseeable series (2024–ongoing)
  A media research project translating electromagnetic field recordings into digital visual compositions, revealing the coexistence of man-made and natural electromagnetic phenomena.

• triptych 11 (2023)
  A glitch-informed audiovisual trilogy investigating pareidolia, memory degradation, and perception through generative sound-image structures.

• Hyksos Talks (2022)
  Art film “Hyksos Talks” by Pitch Shifting (Grgur Savic, Sanja Star)

• Holography Green's function (2023)
  Art film “Holography Green's function” by Pitch Shifting (Grgur Savic, Sanja Star)

• Echoes of the Matrix (2025–ongoing)
  An interactive audiovisual installation that uses ultrasonic field recordings and computer vision to reflect on invisible energy systems and the entanglement of human presence with technological perception.

• Sound Pollution at Lückstraße (in progress)
  A week-long 24/7 siren-field recording turned generative installation, examining urban sound pollution’s impact on health and perception through data-driven audiovisual abstraction.
