Sound

Sound: So much of the material on this site is about sound; how to capture it; clean it; disseminate it, etc. Sure the OHDA site is also about history, and how voices tell stories, but one essential foundation is sound. If you are going to work with sound it is worth knowing a bit about how voices, horns, airplanes, violins, all create vibrations, and our ears turns these into sounds. If you are feeling a bit ambitious, take a little time to watch/listen to this video on how we humans, with our ears, process as sound the vibrations our world produces nearly nonstop. The video comes from the Khan Academy, a site that includes thousands of wonderful instructional videos on an extraordinary range of topics.
