First thing I'd suggest is getting the tempo right for the acapella and then adjusting your project tempo to match. Once you have the correct tempo for the acapella, then you can explore the possiblities of speeding it up or slowing it down.

Honestly, in Cubase I do not have an easy answer for this, but Ableton Live makes this type of tempo stretching or compressing VERY easy. I'd recommend doing it in Ableton if you have it.

Actually, I use Ableton on a second computer as an outboard sampler for exactly these types of operations because its SO easy in Live.

play the original track in a cdj or dj software program and find the tempo, then either adjust the tempo of the acapella or the track. but the tempo u see on the cdj or dj software may not be 100% correct, so loop it and turn the click track on and see if it lines up.

+1 for Ableton Live. It really works like a charm.

Otherwise its not too difficult either. You have to find out the BPM of the original song, I usually do this by using a BPM tapping function.

Then align the first measures of the acapella to the beat. Its a bit trial and error, but after a few minutes you should be able to make it fit.

I usually zoom in very closely on the wav, so I can see the actual waveform of the vocals. High peaks usually mean this is the attack point of a sharp vocal sound.

Lets say for example your acapella is something like "close your eyes". Zoom in on the wave and find the peak, which should be the "k" sound of "[klose]" (however it is spelled in phonems). the "k" is a hard consonant which should make it easily detectable from the shape of the waveform. Make sure the peak of the "k" is exactly placed on the line that marks the beginning of the beat and bar, usually with the kick.

I dont want to make this too much of a science, because it isnt. Just make sure the important phonems are hitting on your first beat of a bar. Once youve done this a few times, you will know how to get stuff in sync.

What cyber said. Ableton is the king for this kind of thing.
