Michael Weidlich is a pioneer in the field of time-coherent (signal-precise) sound conversion and one of the world leaders in this field. His development and application of a testing technique for the analysis of the transient response of loudspeakers provided a profound understanding of their conversion behaviour and of the interaction of sound sources with room acoustics. His concept of "time-coherent" (signal-precise) conversion has reached a very high state of maturity.
