dEchorate: a Calibrated Room Impulse Response Database for Echo-aware Signal Processing
This addresses the need for standardized data in acoustic signal processing research, offering a resource for benchmarking echo-related methods, but it is incremental as it builds on existing database efforts.
The paper introduces dEchorate, a calibrated database of measured multichannel Room Impulse Responses with annotations for early echo timings and 3D positions, providing a tool for benchmarking methods in echo-aware signal processing tasks such as speech enhancement and room geometry estimation.
This paper presents dEchorate: a new database of measured multichannel Room Impulse Responses (RIRs) including annotations of early echo timings and 3D positions of microphones, real sources and image sources under different wall configurations in a cuboid room. These data provide a tool for benchmarking recent methods in echo-aware speech enhancement, room geometry estimation, RIR estimation, acoustic echo retrieval, microphone calibration, echo labeling and reflectors estimation. The database is accompanied with software utilities to easily access, manipulate and visualize the data as well as baseline methods for echo-related tasks.
