This engineering brief presents open-access 3D sound recordings of musical performances and room impulse responses made using various 3D microphone arrays simultaneously. The microphone arrays comprised OCT-3D, 2L-Cube, PCMA-3D, Decca Tree with height, Hamasaki Square with height, First-order and Higher-order Ambisonics microphone systems, providing more than 250 different front-rear-height combinations. The sound sources recorded were string quartet, piano trio, piano solo, organ, clarinet solo, vocal group, and room impulse responses of a virtual ensemble with 13 source positions captured by all of the microphones. The recordings can be freely downloaded from www.hud.ac.uk/apl/resources. Future studies will use the recordings to formally elicit perceived attributes for 3D recording quality evaluation as well as for spatial audio ear training.
