And I'm not talking about sounds that hold some special memory, or that evoke a certain sensation. I go through little phases every now and then where I want to explore a particular type of sound fairly heavily. My latest one is electronics and the interference patterns they induce. Every once in a while I get the recorder out and see what I can find where I'm at. It's amazing how they vary so much in characteristics. I've found some interesting ones at home this week; I've posted a few on my website if you're interested at all (http://www.dynamicinterference.com/2010/07/23/electronic-interference/).
Anyone else go through these little phases? If so, what are some of the sounds you've gone after?
