This mid-side stereo recording was made approximately an hour before dawn¹ in Northeast, Minneapolis on July 9th, 2016. Other than instances such as bugs hitting the microphone blimp, there are few edits in the recording. I did roll off at 60 Hz; on my system this has a slight effect on the train sounds, the first of which appears around minute 20, but I felt the cut was beneficial in getting rid of some other boominess of the air. The train still sounds accurate in relation to where I was².
