Room acoustics is a dominating factor for the resulting sound of any amplified or acoustic show. The room acoustic situation in a venue is usually a given, not influenceable.

However, as a sound engineer we want more. This brief presents the authors work in two venues working the room acoustics from a sound engineers point of view.
