Please, you are really one annoying pest. Can't you just shut up and go away? Frankly no one cares about your opinion. So simply just stop posting.
He knows what he's talking about. And truly, what he said was perfectly relevant and correct; even complimentary to you, since he assumed you knew what an instrumental really was (since you were talking about it); I however did not assume anything about what you knew or did not know and it appeared that there was some confusion of terms, which I brought forward.
As I noted afterwards, and instrumental is <NOT> a filtered track. It's a completely separate recording created by the same artists (usually the same artists; at any rate it's a completely separate studio recording). So, when you respond "Hopefully that might encourage someone to make it exist." when somebody notes that what you are looking for doesn't exist-
in the context of what an instrumental is it is presumptuous; the fact that you are looking for an instrumental (or so you said, you really are just looking for a filtered audio track of the non-instrumental version) and think somebody should make it exist if it doesn't exist implies that you believe the original artists- or really anybody with studio equipment and the willingness to perform the piece- should make it simply because you want one, it is perfectly valid to reply with something like "You really do think the world exists to supply your requirements, don't you?".
The only reason I
didn't say something to that effect was that I guessed you had no idea what an instrumental really was and may in fact have meant a filtered, "karaokeized" version of the actual track, which takes far less effort (effort that still needs to be done, no less). It was only by chance that I really considered it. In fact, in many ways - and perhaps to his chagrin- Salmon Trout overestimated you, by assuming you knew what you were talking about (what an instrumental was); I on the other hand doubted wether you really knew what it was you were after. With that in mind, the heckling you received ought to be received at least in small part as a compliment.
I've tried a few. Audacity didn't turn out too good neither did some of the plugins in it. Centre pan remover? How do I figure out the centre D:
Thing is, filtering out the vocals will always remove other portions of the audio, resulting in it not turning out to good; and it hardly ever removes all of the vocals.
Actually, TBH a better approach might be to search for a MIDI file of the piece; that will, by definition, be purely instrumental.
