This is my recording of the 4th of July for 2019, done similarly to 2018. Microphones are inexpensive electret capsules encased in facial tissue. I used phantom power to electret plug-in power adapters from Naiant Studio to connect the electret condenser microphones to balanced XLR inputs.
This is a wide stereo recording. One microphone was placed outside a window facing west in my living room and the other outside a sliding door on the east side of the living room. The metal window frame of the living room window has a wire running from it to my Focusrite Scarlett 2i2 audio interface to reduce hum pick-up. The audio was captured with VSTHost and a little light processing performed with Audacity audio editor. All of that was done on an inexpensive laptop computer running Windows 10.
