Open Database of Spatial Room Impulse Responses at Detmold University of Music

This repository contains an open source database of Spatial Room Impulse Responses (SRIR) captured at three different performance spaces of the Detmold University of Music. It includes the following rooms: 

• Detmold Konzerthaus (medium sized concert hall, ~600 seats).
• Brahmssaal (small music chamber room, ~100 seats).
• Detmold Sommertheater (theater, ~300 seats).

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 and a Room Acoustic Enhancement System. SRIRs of an ensemble of focused sources on stage and with conditions of increased artificial reverberation are also included.

The database is organized in 3 sets:

- Set A:

Source: Single Source measurements.

Receiver: Open Array and Dummy Head.

Rooms: BS, DST, KH

Special configurations: Artificial reverberation, music stand on stage

- Set B: 

Source: Loudspeaker and WFS orchestra

Receiver: Open Array.

Rooms: KH

- Set C:

Source: Loudspeaker orchestra

Receiver: Dummy Head and Omni8 array

Rooms: KH

Further details on the measurement procedure and acoustical analysis of the RIRs can be found in the following publications:
