Concert Hall Impulse Responses - Pori, Finland ---------------------------------------------- The impulse response database described in this document is available for download from http://www.acoustics.hut.fi/projects/poririrs/. Contents of the document: 1. Introduction 2. Microphone and channel specifications 3. List of files 4. References 5. Copyright 1. Introduction --------------- The responses included in the database were measured in the Promenadikeskus concert hall located in Pori, Finland. The responses are provided as 24-bit wav files including 2-5 channels depending on the type of the response. Each wav file includes the combined response to an omnidirectional dodecahedron loudspeaker and a subwoofer. The responses have been measured with 3 source positions on the stage (S1-S3), 4 receiver positions in the audience area (R1-R4), and 3 receiver positions on the stage (P1-P3). All provided responses are system compensated and denoised. 2. Microphone and channel specifications ---------------------------------------- Microphone directions are specified in a Cartesian coordinate system. The positive X direction (front) for each receiver position in the audience area is defined as the direction towards the stage perpendicular to the backs of the seats in the corresponding position. For the receiver positions on the stage, the front is defined as the direction perpendicular to and pointing towards the front wall behind the stage. Positive Y and Z directions are defined as left and up, respectively, when facing the front. The utilized microphones and channels are defined as follows: DPA 4006 Pair of DPA Type 4006 omnidirectional microphones facing the front with a distance of 10 cm between them in the left-right direction. L = leftmost microphone, R = rightmost microphone. HATS Brüel and Kjær HATS dummy head custom fitted with DPA Type 4053 microphones, facing the front. L = left ear input, R = right ear input. HATS, d.f. EQ Same as HATS, but diffuse field equalized [1]. Pearl Pearl TL-4 stereo condenser microphone with cardioid directivity patterns. L = cardioid facing left, R = cardioid facing right. SIRR SoundField B-format signals processed with the SIRR method [1] for reproduction with a standard 5.0 loudspeaker setup. Loudspeakers for the corresponding channels should be located in the horizontal plane equidistant from a listener with the following azimuthal angles: left (L): 30, right (R): -30, center (C): 0, left surround (LS): 110, and right surround (RS): -110. SoundField B-format signals from a SoundField MKV microphone system. W is an omnidirectional signal and X, Y, and Z have figure-of-eight directivity patterns with positive directions aligned with the corresponding positive coordinate axes. 3. List of files ---------------- The measurements with different microphones have been packed into individual zip files. Furthermore, measurements with receivers on the stage are available in separate packages. The full database includes the following response packages: File Contents Channels Src Rcv Microphone ---- -------- -------- --- --- ---------- binaural.zip s1_r1_b.wav L,R S1 R1 HATS s1_r2_b.wav L,R S1 R2 HATS s1_r3_b.wav L,R S1 R3 HATS s1_r4_b.wav L,R S1 R4 HATS s2_r1_b.wav L,R S2 R1 HATS s2_r2_b.wav L,R S2 R2 HATS s2_r3_b.wav L,R S2 R3 HATS s2_r4_b.wav L,R S2 R4 HATS s3_r1_b.wav L,R S3 R1 HATS s3_r2_b.wav L,R S3 R2 HATS s3_r3_b.wav L,R S3 R3 HATS s3_r4_b.wav L,R S3 R4 HATS bin_dfeq.zip s1_r1_bd.wav L,R S1 R1 HATS, d.f.
