Good question! The two words do share common usage, but obviously there must be a difference otherwise one or the other would have been lost through redundancy. The best answer I can think of is that in the science of sound production or capture, we would tend to use audio. We obviously need to add more to the page to make the distinction clear.--Echoez71 (talk) 16:36, 20 June 2008 (UTC)[reply]
I generally agree with Echoez71. To me 'audio' is a broad description to categorize all kinds of 'audible' sounds, whereas a sound is more of a discreet event. Speaking of ontologies, sounds of speech, music, noise, etc. our ears are sentive to fall under the audible spectrum of frequencies and comprise the audio (signals) we can perceive. To summarize, sounds are discreet events and audio is a scientific category to group the different types of sound under. Though the notion of sound as audio does have a use, especially among electronic music artists I observed. --Mokhov (talk) 17:31, 20 June 2008 (UTC)[reply]
