Heavily involved in sound and video recording, production and packaging, with experience ranging from electronic design to color prepress design, separation and film processing, to 3D modeling and animation and acoustic design.
I also do some music composition and arranging in my spare time, for my own enjoyment and the occasional video production that needs BGM.
I also build very large, expensive custom sound systems. I'm a specialist at designing high efficiency, broadband Hemholtz resonator subwoofer cabinets with extended low bass response. I've been designing speaker systems for more than forty years.
