Recordings and RIRs
This is a complete dataset of measurements and recordings to facilitate the evaluation of speech and audio enhancement algorithms in realistic environments. The measurements were carried out in an actual meeting room at the conference center of the University of Patras. A dummy head fitted with a mouth simulator was used to simulate a moving speaker.
Open Air Library
An expanding library of downloadable acoustic impulse responses (IRs) from interesting buildings, spaces and other sources. The library contains also sounds recorded in an anechoic environment
Speech datasets
A list of speech datasets with detailed attributes and links to software baselines and evaluation results. Each dataset may be used for one or more applications: automatic speech recognition, speaker identification and verification, source localization, speech enhancement and separation.
Aachen Room Impulse Responses
The Aachen Impulse Response (AIR) database is a set of impulse responses measured in a wide variety of rooms. It contains binaural room impulse responses (BRIR) measured with a dummy head, but also with omnidirectional microphones in different locations with different acoustical properties, such as reverberation time and room volume. The distance and the azimuth angle between head and desired source is varied.
HRTF and BRIRs database
An eight-channel database of head-related impulse responses (HRIR) and binaural room impulse responses (BRIR) is introduced. The impulse responses (IR) were measured with three-channel behind-the-ear (BTE) hearing aids and an in-ear microphone at both ears of a human head and torso simulator. In addition to the HRIRs derived from measurements in an anechoic chamber, sets of BRIRs for multiple, realistic head and sound-source positions in four natural environments are provided.
