What the Audio Window Is and Isn’t

	The Audio Window, in all its glory (from Total Recording, by permission of KIQ Productions).

So there you have it. All sounds that humans hear exist within this range of frequencies, amplitudes and times. There are other frequencies, amplitudes and time periods that exist in air, but humans don’t perceive them as sound, and they have little or no relevance for our audio production work. So, in a simple way, you can think of this space, this confluence of physical dimensions, as our audio sandbox or playpen. Here’s where our work is done.

At the same time, it is really important to keep in mind that there is much more to it. Within this space, there are many features and facets of sounds and our auditory system that make our actual hearing dramatically richer, more powerful and more moving.

Next month, we’ll talk about how we perceive pitch.

Happy dimensions!
