Boomer The Dog That was fun, a kind of capture I hadn't seen before and in real time. The thick low strings looked the most sine, and you could see the actual non sine waves, like triangles in the higher strings. That would probably be close to what a wave editor would show too.
I hadn't thought that harmonics showed up in the strings of a guitar at all, it was all sine, but that the coloration came from the box resonating.
Neat-o, hello groceries.
fluffy This isn't what the strings actually look like while vibrating. It's just an artifact of the iPhone 4's really shitty rolling shutter.
