Thomas Ankersmit (1979, Leiden, Netherlands) is a musician and composer based in Berlin and Amsterdam.

Acoustic phenomena such as sound reflections, infrasonic vibration, otoacoustic emissions, and highly directional projections of sound have been an important part of his work since the early 2000's. His music is also characterized by a deliberate misuse of the equipment, using feedback and disruptions to the signal, and the extremes of frequency and dynamics, to create visceral but finely detailed swarms of sound. Since 2006 his main instrument, both live and in the studio, has been the Serge modular synthesizer.

Ankersmit collaborated with Sicilian composer/performer Valerio Tricoli on Forma II, a series of electroacoustic pieces released on the PAN label, and on music based on the acoustics of abandoned radar domes. Both projects were honoured by Ars Electronica. Other recent collaborations include recording sessions with Kevin Drumm at GRM in Paris, and a new Phill Niblock composition for Serge modular synthesizer (Niblock’s first piece for an electronic instrument).
