Help with Reverse Reverb

[DJSolo]

I am trying to do the reverse reverb trick for my track but It doesnt seem to be coming out as well as I hear on other tracks. The way im doing it is taking my vocals into Sound-Forge, reversing them and then adding a reverb with a decay time of 5 seconds. I then reverse the audio again and copy the beginning part of the reverb sweep and paste it infront of the dry vocals. My problem is that my reverse reverb isnt lasting as long as the ones I hear and it also sounds reverby while the others dont. Let me show you an example:
Here is the reverb I want to achieve.

Here is the reverb I get with Soundforge.

Are there any VSTs that do this automatically? Any tips on how to get the sound im after?

I'm sorry about that. Try now, it should work.

I usually proceed like this (in cooledit and FLstudio)

1 reverse the sample

2 apply a long reverb but using automation (reverb level) I apply 0 reverb to the initial reversed sample and sweep to the max reverb level wanted just about the end of sample using a curve with negative tension like this:

___/

3 reverse again everything et voilà: no need to copy the beginning part of the reverb sweep and paste it infront of the dry vocals (otherwise the reverse reverb will not last as long as the commercial ones, and you'll hear a kind of loss of fluidity when the reversed-tail ends and the vocal sample starts).
The automation trick on point 2 is used to avoid sample mudding...in fact the reversed reverb level envelope automation curve should be like this:
\____

that is max at the beginning of the vocal sample and then fading out (fast or slow you decide)inside sample playback.
The other question is just a matter of taste: you have to choose a kind of reverb that suits your needs...a good hint would be this:

take some commercial reverse reverbs you like and reverse them again...listen to them and try to reproduce that timbre with your own tools (soundforge or whatever)

Try using Convo Boy and activate 'Reverse' on the IR.

There is a big difference between "reverse" algorithmns that are expected to work in realtime, and real reversed reverb. SIR can reverse the samples used, but all this is really creating is an Inverse Reverb. That's where the tail ramps up and then cuts off - so it's very cool and unnatural, but it always occurs AFTER the dry sound. A real reverse reverb occurs BEFORE the dry sound, and obviously can't be done in real time. The real thing is done by taking your sample and applying a 100% wet reverb. Export this to audio, and then reverse this reverb tail sample and align it with the dry sound. It achieves a 'sucking up' sort of effect. I think short reverb tails are good for this, unless you want a big dramatic effect. There is no magic in this, and i'm always suprised that commercial vendors actually sell reverse samples. That's just a waste of disk space, because any reverb can be reversed.

you also may want to run a limiter on the vocals after applying the reverb, to bring up the level of the tail. just be gentle with it, lest it overwhelm the mix in the final mastering stage.

The trick part I found when doing reverse reverb is that you have to find a reverb that is full and decays quickly. That always gave it a nice reverse. Now most of my reverse reverb was on drum parts: reverse snare, reverse clap, reverse kick, etc. If you were doing something like ambient vocals then maybe even a longer decay. Sorry I haven't listened to your sample.
