Buchleitner was born in Stuttgart, Baden-Württemberg, Germany and spent his childhood in Bad Wildbad in the secluded northern Black Forest.
He attended the Gymnasium in Neuenbürg and the Goetheschule Freie Waldorfschule in Pforzheim.
Without any college education, he surprised the audio community in 1982 with the Quantec QRS "Room Simulator", a digital reverberator he designed and built by himself, considered to be among the all-time favourites in this field and a legend for years.
He also took part in numerous multimedia projects, among all together with Dietrich Lohff and Dieter Mack.
Quantec equipment is used several hundred times throughout the world by radio and TV broadcasters, recording, dubbing and film studios, music venues and theatres as well as many famous rock and pop musicians of international standing.
