What other professionals say:

“I’ve known Klaas Peter for well over a decade and during this time, I have employed Klaas Peter in numerous roles and can attest to some of his key qualities that made me choose for him time and time again. Whether he has to produce the entire sound palette for a cartoon series, sound effects for video games or complex mixing of an orchestral soundtrack to a full-blown console title, Klaas Peter manages to stand out creatively, technically and with respect for time related constraints without concessions to quality. Klaas Peter knows how to hit the right note. Come to think of it, I would be hard-pressed to find a word that better fits his overall description than gifted.”
