I recall a little app called soundEdit (I think) that ran in the Mac back in the mid 1980's. I think it was shareware (at least it was ubiquitous). The editing primitives were fairly cleanly defined and, had a reasonable metaphoric correspondence to the familiar drawing actions. There was a thing where you could grab a few seconds of sound and copy it and paste it; you could drag and drop; you could invert (by just subtracting each of the tones from a ceiling) you could reverse (by inverting the time axis). You could even go in with your mouse and drag formants around. It was pretty cool. It would not be a major task for someone to standardize such an interface and I believe any patents would be expired by now.
