Abstract: This manuscript presents an open source database of Spatial Room Impulse Responses (SRIR) captured at three different performance spaces of the Detmold University of Music. It includes one medium sized concert hall (Detmold Konzerthaus), one chamber music room (Brahmssaal) and one theater (Detmold Sommertheater). The collection contains approximately 600 multichannel RIRs corresponding to several source and receiver configurations. For each room we include measurement positions on stage and at the audience area captured with both an artificial head and an open microphone array compatible with the Spatial Decomposition Method (SDM). The Detmold Konzerthaus holds a large scale Wave Field Synthesis system allowing the rendering of virtual sources and artificial reverberation. SRIRs of an ensemble of focused sources on stage and measurements with artificial reverberation are also included.
