Open Database of Spatial Room Impulse Responses at Detmold University of Music
收藏资源简介:
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.

V.; Sahin, B.; Eddy, D; Kob, M.: <strong>"Open Database of Spatial Room Impulse Responses at Detmold University of Music"</strong>, <em>149th Convention of the Audio Engineering Society, </em>2020. The database is organized in 3 sets: <strong>- Set A: </strong> Source: Single Source measurements. Receiver: Open Array and Dummy Head. Rooms: BS, DST, KH Special configurations: Artificial reverberation, music stand on stage <strong>- Set B: </strong> Source: Loudspeaker and WFS orchestra Receiver: Open Array. Rooms: KH <strong>- Set C:</strong> 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: <strong>Set A</strong> Amengual Gari, S.
