So I know that by combining these, the side channel is the acapella or something very close to it.

However, whenever I line up the waveforms, it seems that the 'acapella' is only so for less than a second. It has to be continuously re-aligned, as if one track is like 0.1bpm slower than the other.

Why does this happen, and how can it be fixed?

Here is a sample of what I've done. You can hear it becoming 'more acapella' and then 'less acapella' if that makes sense.

have you inverted one of them

Die.

Hi, I don't wanna sound like an ass now. But you WILL get flamed for asking this question. There are daily newly registered members here who are asking the same questions over and over again without searching the forum first which in return makes the most members of this forum quite irritated. If you check one of the first sticky-posts of this section in the forum entitled "Please Read: Music Production FAQ", you will find:

quote:

Questions you will never have answered on this forum: 1. How do I rip a [vocal / drumloop / other element] from a track? You don't. You can't. There is an article here that explains in detail the challenges behind eliminating the vocals from tracks to create a "dub" - the exact same principles apply to "extracting" the vocals from a track to obtain an acapella. And of course, these principles apply equally well to other elements of a track, not just the vocals. In any event, bootlegs are a violation of copyright law and are therefore not supported by forum members and owners, and not to be discussed on this site. Please and thank you.

Have a good day and good luck with your acapella!

I don't actually care about the acapella, I know they aren't legal to make a mix with and I wouldn't even do it 'for fun' as some people say. I did do a forum search and didn't find anything. I know about the sticky, I've read it, perhaps I just phrased my original post wrong.

I was interested about the change in waveforms and the technical aspect of why they vary.

If I showed up on a chemistry forum and asked a question about how to obtain industrial grade ether and how to apply such in order to obtain an essential oil from my amalgam-treated distillate, chances are the deduction would be made that I may be trying to synthesize any number of highly illegal drugs.

If the forum posted a rule, explicitly stating not to ask for any advice relating to the manufacture of drugs, like MDMA or Meth, but I clearly post an inquiry relating to its manufacturing, I don't think I can blame simple inquisitiveness.

1. Get a song.
2. Run it through a major low pass filter, until it sounds totally silent.
3. Cock slap your computer.

I don't believe this, but OK, I'll humour you:

1. Mastering
2. Lossy compression

I'm sorry that you don't believe me. Maybe I shouldn't have mentioned the acapella part and gotten a straight forward answer right away.
I don't know who would want to make a low grade acapella, make a so-called remix and infringe on copyrights.

I thought it might be due to lossy compression, but I didn't think that it would effect the timing, even if it's only by a ridiculously small fraction.
