ChurchIR: A Dataset of Multichannel Church Impulse Responses for Spatial Audio Applications

ChurchIR is a dataset of multichannel impulse responses acquired in the church of Saints Marcellino and Pietro in Cremona, Italy. The church, currently used as a concert venue, offers a rich acoustic environment that is valuable for research in virtual acoustics and spatial audio. The dataset includes 30 impulse responses (IRs) measured in the stall area for three distinct source positions. The IRs were captured using both an omnidirectional microphone and a 4th-order spherical microphone, allowing for detailed spatial analysis. ChurchIR can be useful for studies on acoustic characterization of concert spaces, reverberation analysis, and spatial audio rendering. Researchers working on virtual acoustics, auralization, and immersive audio applications may find this dataset particularly valuable. This dataset contributes to the understanding and modeling of church acoustics, supporting both scientific research and practical applications in concert hall design and heritage preservation.
