Immersive environmental soundscape capture and annotation is a growing area of audio engineering and research, with applications in the reproduction of immersive sound experiences in AR and VR, sound classification, and environmental sound archiving. This Engineering Brief introduces CityTones as a crowdsourced repository of soundscapes captured using immersive sound capture methods, that the audio community can contribute to. The database will include descriptors containing information about the technical details of the recording, physical information, subjective quality attributes, as well as sound content information.
