He worked with early synthesizers and vocoders, and contributed sound effects to almost thirty records and movies.

[4] Krause has a Master's degree from the Brooks Institute in Santa Barbara, California (1996), and an honorary doctorate from the University of Essen, Germany (1999).

The company which he co-founded, MetaCreations Corp., began as HSC Software, which released the first version of Kai's Power Tools in 1992.

This name remained until 1997, when a rapid series of mergers with Fractal Design, RayDream, Specular, and RTG (Real-Time Geometry) necessitated a new identity for the growing organization: MetaCreations.

The interfaces of Krause's products used soft shadows, rounded corners, and translucency prior to their wider adoption.
