Default Fade in/out controls for impulses in Reaverb.

I feel like Reaverb really needs this, I was using Reaverb and trying to shorten impulses then realized that while you can shorten an impulse with trim there is no fade in and out controls for a more smoother and realistic sound when editing the length of the impulse. fade in and out comes standard on other convolution Reverbs why not the one in Reaper?

Would like to be able to trim samples interactively like in ReaSamplOmatic5000, and also apply fade-in and -out. Would be very useful.

Yes, please, add fade out for impulses. A simple function to add linear fade out will do. Isn't this something that can be done easily and quickly? Just a simple fadeout fader below current Length setting?

Developers, are there any plans in this regard? At least fadeout? If impulse is shortened, at present it is just cut off, which is not very musical in most cases. A simple fadeout in Trim/Gain/Stretch process would be fine. Can you please add this?

+1 to this. The Trim/Gain/Stretch is great but the trim is just a hard cut.

Maybe a separate "apply envelope" module that you can add to the process chain? Then you could add it after the Trim operation to apply AHDSR envelope to the result, with the point positions determined by, say, percentage of the impulse length.

I would like to see the "Fade Out" module added to ReaVerb. I think, that it
wouldn't break the backward compatibility with older projects this way.
Definitely usable feature.

It's not possible / viable to modify the impulse itself in runtime, as a convolution works by creating an FFT of the impulse when loading, and using this data in runtime.

There are some operations that possibly can be done to the FFT data of the impulse in runtime (e.g. Volume or EQ).

But those in fact already can be accomplished by automating "Wet" or adding an EQ and automating same, so I suppose this is not the target of this feature request.

"fade in and out comes standard on other convolution Reverbs why not the one in Reaper? "

these other tools are valuable because they're better than the stock plugins.

Fog Convolver is another example of a convolution reverb with Fade in and out, plus HP and LP filters, true stereo operation and library of IRs. It's only $65.

What exactly is supposed to trigger the ADSR ?

Although Fog Convolver is awesome, I'm considering switching back to ReaVerb since it's retaining IR file within project files. Good for carrying the project around.

Yet only feature missing between the two is ReaVerb doesn't have fade in/out controls. That would be very nice to have!

I saw there are great updates being made to ReaVerb, can I ask for a Fade In/Out module? Nothing fancy, just something that alters the final impulse (and not ADSR).

Here's how it functions in Fog Convolver:

I wish nothing more than fully switching to Reaverb and leave Convology XT and Convolver behind, but the lack of ADSR or at least Fade in/out with adjustable curves is the only thing that prevents Reaverb to be the best convolution reverb out there (according to me of course).

So BIG +1 here.

Each and every sample would (as it already does but with A, D & R stuck at 0ms and S stuck at 100%).

(Sorry I'm 4 years late)

EDIT: the trigger for R wouldn't actually be the sample, it could be the end of the IR with a negative value.

???

There is one sample after the other as a fixed rate of (e.g.) 48 KHz. How should that trigger an ADSR ?

Well, each sample triggers an IR file that is several samples long, the ADSR would be applied to this set of samples, not to the original (dry) one.

Maybe I misunderstand convolution, in such a case let's call it an analogy. What I mean is that what happens at "Start pos"* is similar to "open Gate" and what happens at "Max len."* (or at the end of the IR file, depending on which comes first) is similar to "close Gate". So together, they are similar to a gate CV, that is an enveloppe CV without ADSR shaping.

The feature I'm longing for is that ADSR shaping (or even DAHDSR).
"A" would have positive values referring to the IR file's start, "D" would have positive values referring to the IR file's start + A, "S" would be a negative trim and "R" would have negative values referring to "Max len."* (or to the IR file's end, depending on which comes first).

The only workaround that I know of is to edit the original IR file, but it is quite inconvenient for live tweaks.


Antoine (sorry, I'm answering late, I missed the notification).


*in "Trim/Gain/Stretch"

Default Something like this


but less ugly of course.

Actually the first "D" (delay, not decay) is already featured as "Start pos." in "Trim/Gain/Stretch".
