  • The same day I found out about the open call for another edition of the beautiful On Air – On Site festival, I stumbled upon the Wide-band WebSDR – a web-controlled shortwave receiver located at the amateur radio club ETGD at the University of Twente.

    I spent hours experimenting with the interface, gliding through frequencies and exploring the radiophonic flux of shortwave radio. The process was full of surprises: fleeting textures, concrete pitches, melody-like gestures, snippets of radio stations, amateur radio operators speaking in various languages — constantly shifting.

    I recorded around two hours of this. The resulting composition draws entirely from the material, using it in its pure form. Only minimal filtering and binaural panning were applied.

    I'm fascinated by the randomness and poetic potential of these transmissions — fleeting encounters, flickers of connection in shifting fields.

    Special thanks to the operators of the WebSDR at the University of Twente for making this tool publicly accessible.
Featuring:

Felix Mayer

Felix Mayer (*1990) is a trombonist, composer, and sound artist based in Braunschweig. In bands,
collectives, and ad-hoc constellations, he explores the boundaries of improvisational and
instrumental practice. His compositional work focuses on alternative forms of notation such as
text and game pieces, video scores, and improvisational concepts.

He creates radiophonic works, installation-based audio plays, and concert-installations in interdisciplinary collaborations with artists from literature, dance, film, and performance. His site-
specific and often multichannel sound installations examine possibilities of communication, connection, and relationship through inherently distorting tools.

Engaging with experiences of fragmentation and shifting perceptions of closeness and distance,
he explores the associative and sonic potential of everyday objects such as tin cans, oil barrels,
and trash bins.
