I didn't edit that recording at all, other than increasing the volume. I plugged my headphones into the microphone jack on my laptop. This particular pair of headphones has its own volume slider, which I turned to the maximum. It's a wrap-around type with large earpieces that can be flipped to face outward. I had them flipped outward here and on my head so they'd be similar to actual ears.

I did edit it a little: I turned the volume up by 250% about three times. The louder the sound being recorded this way, the better.

(I was recording and turning up the volume with wavepad. I tried noise reduction on it after posting, though I only used one method (Wavepad has three different methods for noise reduction). The sound was more watery afterward, but the spacial aspect seemed to be preserved. I'm worried that I can't use this method to reduce background noise if I'm trying to record 3D ambiance. )

After this, I decided I'd take my laptop with me and record the trip to get breakfast this way. I considered that people might think it odd that I was walking with headphones on outside my hood; only after I set out did I realize that such people would probably find it more odd that the headphones were turned inside-out. There was hardly anyone else up at the time, fortunately, and had they been, there are far bigger nerds in this area (though, I don't think any of them walk around with inside-out headphones on over a hood).
