Multi-Angle, Multi-Distance Microphone Impulse Response Dataset

This archive contains data generated as part of the PhD research of Juan Carlos Franco, investigating the timbral attributes related to the incident-angle-dependent response of microphones. The dataset of microphone impulse responses (IRs) comprises 25 microphones, including a Class-1 measurement microphone, covering the polar pattern variations of 7 of the microphones. The measurements were performed following a quasi-anechoic method, at incident angles from 0° to 355° with an angular resolution of 5°, and at source-to-microphone distances of 0.5 m, 1.25 m and 5m. Both normalised (-1 dBFS peak) and raw versions of the IRs have been rendered at bit-depths of 24-bit and 32-bit, with a sample rate of 48 kHz. A detailed description of the measurement procedure, as well as the equipment used, is provided in the associated journal paper [Franco et al. 2021].
