Afternoon in an urban backyard. Ambisonic four channel b-format recording recorded with the coresound tetramic in pittsburgh, pa. *note: you will need to decode this b-format ambisonic file with a plug-in such as the (free)surroundzone2 which allows you to decode the file to a surround, stereo, or mono format. Also note that these are fuma bformat files (and opposed to ambix bformat).
