Reversing Reverb help!
Hey there, I'm currently building a reverse reverb plug-in for a university project, similar to what you hear in a lot of current electronic music, the reverb is complete after a lot of work, hassle and help from these forums so thanks very much for that!
I'm now struggling on how to then reverse this, I may need things spelling out for me painfully simply so apologies for that!
Thanks very much.
Hi
I built this super-quick so it's a little untidy, and maybe imperfect, but it works and it's commented so HTH:

Yeah, this might actually NOT be what you're after LOL.
The effect you refer to applies a reverse reverb effect to each sound or utterance, before it appears. It was probably big in the 80's. It's usually achieved in audio sequencers by recording the wet reverb on a separate bus/track, then segmenting and reversing each reverb tail, then situating them in the sequencer before each transient or onset, so the chronology is forward but the tails are reversed, and precede each onset (Phil Collin's drum sound, anyone?).
There are some FX plugins that can fake this, but the above mentioned effect is impossible to achieve in realtime because the reverb can't predict what sound will occur in the future. Unless you delay the incoming signal. Then it gets too complicated for a ten minute rough sketch, so . . . .
Ahh I see, what a shame! I have no idea how this was achieved in this plug-in for Max msp, but it's been done here: http://plus.pointblanklondon.com/reverse-reverb-fx-in-ableton-grab-the-max-for-live-device-for-free/
But of course I wouldn't want to be accused of copying any work from another max project, so I may just have a build a simple multi-Fx plug-in and include the reverb I made, thanks very much for your help!
Just had a look at your file thanks so much for this, I'll be sure to have a tinker and see if I can come up with what I'm looking for!
Looks like it's not done in real-time on the linked M4L device:
"as we weren’t able to distort the very essence of time for this device, you will need to copy the initial part of your vocal exactly 8 bars before it starts onto a track with the Point Blank Reverse Reverb loaded. Once the device is armed and Live plays from that exact point, it will automatically trigger the reverse effect so it syncs with the original vocal 8 bars later and then we recommend you flatten this effect once you are happy with the sound."
did you try convolution with reversed Impulse responses? Might be not what you are looking for, but it's a nice effect and somewhat related (and fully realtime).
Ah I see, d'you have any idea how I could achieve the same effect? Thanks!
