This sound was captured accidentally in my living room as I fiddled about getting ready to record my piano. The hardwood floors created some serious low frequencies up the mic stand as I was moving around.
If you listen carefully, you can really hear the shape and temperature or the room. I added a significant amount of gain to get this into an audible range. Otherwise, it’s really just an example of a recording that I never intended to make.
