Dopplereffekt (German for 'Doppler effect') is an electronic music act from Detroit which has been active since 1995, and whose main member is producer/artist Gerald Donald (also one half of the band Drexciya with James Stinson). Another member is To Nhan Le Thi. The group released a compilation album, Gesamtkunstwerk, in 1999, and were inactive until 2003; since then numerous albums have been released.

While the musical style and the act's image changed radically during a non-release period from 1999 to 2003, two steady characteristics are the display of a thematic affiliation with science and the obvious use of pseudonyms and the hence rumored but unconfirmed identities of the members.

The group also has political influences, with the cover of Gesamtkunstwerk featuring a white hammer and sickle on a black background. In an interview, Gerald Donald stated that the album cover was intended to pay homage to socialism as an ideal political concept in theory.

The act has played gigs regularly across the globe. They perform live using two Korg Triton workstations.
