An electronic music project for ambient electronic and experimental techno started by Danny Kreutzfeldt in Aarhus, Denmark during 2003. It was officially discontinued in 2009 with the release of Iktus after a long production hiatus. Subsequent releases such as Mtnada feature older works. Upon it's conception for the release of the experimental techno album mikro in 2003, Sgnl_Fltr was only one among many monikers used by Kreutzfeldt.
