Hi all,

I have tried some searches here, but unfortunetly I have so little idea what I am talking about I don't even know what to search for. But here's what I am trying to do (in Sound Forge 7):

I want to extend a scream with an echo or a delay, but I just want it to be a steady echo then a slow fade out (see what I mean - I can't explain very well - my apologies).

I'll try to demonstrate:

I have a recording that sounds like this:

AAAAAAaaaaahhh!

I want it to sound like this:

AAAAAAAAAAAAaaaaaaaaaaaaaahhhhhhhhhhhhhhhh........

(isn't this descriptive?)

Delay or echo gets me multiple echos like this:

AAAAAA AAAA AAA aaa aa aa aa aa hh hhh hh hh h h.....

Unless I turn off "multiple delays", which seems to give me nothing at all.

Reverb seems like it is possibly what I actually want, but in order to extend and sustain the scream, reverb (naturally, I guess) makes the dynamics of the sound completely different (metallic - as if in an echo chamber).

Does any of this make any sense? Is what I am trying to do impossible?

Could anyone even point me in the right direction as to what filter, etc. I should be trying?

I think I need an "echo sustain" or something like that!

Thanks for the pity or help.

Bret

Try using PROCESS>TIMESTRETCH This will give you, "AAAAAAAAAAAAaaaaaaaaaaaaaahhhhhhhhhhhhhhhh!!!!!" Now take this and add a volume envelope (hit the "V" key"), now towards the end of the file click on the volume envelope and add some points so you can create a fade out on the "hhhhhhhhhhhh".....which will give you the "hhhhhhh.......", therefore both processes together will give you "AAAAAAAAAAAAaaaaaaaaaaaaaahhhhhhhhhhhhhhhh............"

You might also try adding a little reverb like a Hall. This would be a perfect effect for using the automated reverb. Try automating the Dry out and reverb out. Towards the end of "hhhhhhhhh", start to bring the dry effect down in level. This will make it seem like the "hhhhhhhhh......." is getting further away from you and fading off into the distance, as if someone has falling down a well. Keep in mind the bigger more reverb out you have than dry out, the further the sound will be down in the well. So you should fade the dry out well before the reverb out.

Hey thanks!

I will try these suggestions later tonight and post my results.

I really appreciate it.

I tried your suggestions, and they work great!

Basically, I just time-stretched the whole scream a little, then faded it out and added a little reverb near the end.

It was just what I needed.

Thanks again!
