Marc Thiemo Kotthoff

I’m Marc Thiemo Kotthoff, a sound designer and audio engineer based in Cologne, Germany. I run INDIE AUDIO, an independent audio collective that functions as a network, a studio, and an open space for developing ideas, marketing talent and realizing audio formats.

With a background spanning live performance, band leadership, and creative project management, I bring a hands-on, collaborative approach to sound, voice and storytelling—covering studio recording, live setups, and audio branding across music, media, and marketing projects.
