Smallest possible audio file to make a 440hz tone?

I want to create the smallest (file size) possible audio file that, when repeated, will sound like a given note (e.g. 440hz A). I think this needs to be just the length of one wavelength, but I'm not sure how I translate that to a length of time, or if the smallest audio format is one in which note duration doesn't matter. I don't care if this tone sounds artificial, but it needs to play natively in Firefox, Safari, and Chrome browsers. Is MIDI the best (most compressed) format for this or should I use something else? And what (ideally free) software might I use to create the files, given access to OSX and Windows XP?
