Gunshots recorded in an open field using iPod Touch devices

Cooper, Seth; Shaw, Steven

Seven different firearms, including four pistols and three rifles, were fired at least three times each, in order, at a target located at a distance of 45 meters from the shooter, in an open field in Gallatin County, Montana.  Sound was recorded from four different iPod Touch devices.

The recordings were started asynchronously, but they can be lined up based on the impulse from the first gunshot. The Matlab file, create_data.m, is provided to pre-process the data for import into Matlab.

The following firearems were discharged in order:
