Field recording is fun but also challenging. A while back I posted a comparison of microphones and stereo techniques. I thought I would add some details about the day I recorded that material which was on new years eve when I decided to give it a go to record some isolated fireworks going off. I purchased an assortment of about $400 worth of consumer rockets and shells.
The day before recording I needed to find a location. Setting off fireworks in Sweden is restricted to new years eve unless you have specific permissions so I wanted to take advantage of that and record it when most people were expecting fireworks to go off. I had purchased a fair amount of fireworks that would take some time to set off, I expected it would take a couple of hours or so I wanted to find a place that was far away enough from residential areas but still accessible by car.
