A1 - Weinzierl, Stefan T1 - Database: Recordings of a Loudspeaker Orchestra with Multi-Channel Microphone Arrays for the Evaluation of Spatial Audio Methods N2 - For a comparative physical and perceptual evaluation of conceptually different binaural rendering techniques, recordings are needed in which all other factors affecting the sound, such as the sound radiation of the sources, the room acoustic environment and the recording position are kept constant. To provide such a recording, the sound field of an 18-channel loudspeaker orchestra fed by anechoic recordings of a chamber orchestra was captured in two rooms with nine different receivers. In addition, impulse responses were recorded for each sound source and receiver. The anechoic audio signals, the full loudspeaker orchestra recordings and all measured impulse responses are available with open access in the SOFA 2.1 (AES69-2022) format.

Some of the room models are based on existing performance venues, however without yielding a perfect match of measured and simulated acoustical parameters. Others are artificial designs which were made to systematically cover a wide variety of room acoustical properties. Each of the 35 acoustical environments included in the GRAP database consists of three components: (1) the room model which specifies source and receiver positions and the acoustic properties of the surfaces, (2) the simulated monaural and binaural impulse responses, as well as (3) the item and factor scores, based on a listening test using the Room Acoustic Quality Inventory (RAQI).
