Since an exact copy of the original data would take an infinite amount of storage, any storage of that same data on a finite storage medium would, by definition, be compression. But whatever.

And that would be raw, uncompressed PCM data, BTW. Don't want anyone to confuse the audio storage format of PCM with the containment system known as WAV (which can contain other audio storage formats). (I realize you said ``wave'' and not ``WAV'', but just to make it perfectly clear....)
