Graduated volume change
Graduated volume change
Is there a /single/ effect that will set the selection volume to 400% at the start linearly grading to 100% at the end?
(I am trying to simplify a multi-effect preset.)
Thanks.

The only thing that would allow you do such a thing is the shape volume effect, but it only supports up to 200% amplification...however if you shaped it to go from 200% to 100% and ran the effect twice, your net effect would be what you want. You could also double the volume of the entire file and run shape volume only going from 200% down to 50%, but I don't believe you'll be able to do it with a single effect.
Thanks for the suggestions.

That's the multi-effect preset I am trying to simplify. Particularly because I want the start %age to be easily adjustable.

That would make out-of-range values in the intermediate. Is GW sure to preserve them? I cannot afford them to be clipped.

Goldwave uses 32-bit floating point for temp storage and processing audio. Provided you make sure you "maximize" before saving it in a 16-bit format, the actual data will not be clipped. it'll look clipped, it might even sound clipped when you preview it, but you can knock the volume back down and it won't actually be clipped.
No I was just telling you the math so you could see that going from 100 to 25% is the same as going from 400 to 100%... well it's one step for me when I do it I know that. Oh well, whatever at least I know what I'm talking about, maybe I don't understand what you're trying to do, NM then.chrisjj wrote:Thanks, but that's two steps.

No, you said:

... which is actually 2 steps.
> well it's one step for me when I do it
Step #1 : 100*4 = 400
Step #2 : 25*4 = 100
If you have a way to do that in 1 GW step, I'd like to hear it.

oh sorry I thought you wanted to also normalize afterward which if you did 100 to 25 you wouldn't need to normalize. I guess you actually want the signal to be 12db over clipping level then for some reason... in that case you can't do it all in one step until Chris (not you.. the developer of Goldwave) changes the code to allow up to 400% in the shape volume effect.
But if your goal was to do 400 to 100 and then normalize the volume immediately afterward then doing 100 to 25 would give you that result all in 1 step that's what I meant. Sorry for the confusion. Yeah it can't be done in one step right now, that would be nice, there's been times where I too wanted/needed to edit up to 400% and wished I could. Maybe Chris will add that one day.

I don't want to normalise. I want only the change that the OP specified.

No I don't. The source signal has 12dB headroom.

OK, thanks for the confirmation and your suggestions.

If you ever manage to wreck the only recording you have of something that is important to you -- and you discover that there is no way to replace it or repair it, you will then discover why I offered that advice.
Okay by me. Do whatever pleases you most.Thanks, but I am batch processing, so that's not possible.
