Extending Audio Echo

jrazz wrote on 2/12/2008, 2:45 PM

I have an audio interview that I want to cut short (between words) and then add reverb to the last word on the left side of the split so that it extends out and echos.

I can't figure out how to do this in Vegas. I do not have Sound Forge so that is a no go. Right now what I am getting is the effect, but of course it cuts out at the end of the event and if I extend it, it keeps going to the end of the entire event.

I am going to try doing an non realtime fx and creating a new wav file and extend the end and turn off loop to see if that is a way around this.

In the meantime, any suggestions are welcome.

Okay. That worked. Thanks :)

What you've struck is one reason SCS have said they don't want to add event level audio FXs. With things like reverb it can get dang confussing when the output of the FX is longer than the event feeding it.

So there's no simple way in Vegas to add reverb to an audio clip and have the reverberation trail off the end of the audio clip?
That would be strange. This is the point of reverb and an often used thing.

This was a limitation of electronic drum machines in the 80s, where the reverb was part of the sound itself and not seperate, so when the drum hit was over, the reverb went away. Helped give us that 80s sound, but I hope we're past that now. :)

The way I found is really quite simple, it is just a work around.

1. split the portion you want reverb on from the main audio.

2. right click, apply non realtime fx (apply any that leaves your sound in tact with no modification).

3. stretch out the file that was created in your last step.

4. right click, apply non realtime fx and choose reverb or whatever effect you want to trail off.

That is how I got it to work.

Here's how I'd try doing this.
Split the audio portion of the clip at the last sentence it's a separate clip.
Drag this down to a new track and apply reverb to it.
Now the reverb can tail off under any new audio track.

So if you apply the Reverb effect to the 'Track' and not the Clip, it will train off normally like you'd expect reverb to, is that correct?

But when applying it to the clip/event it cuts off at the end of the clip/event?

If that's the case, I see how that makes sense.

I see you have found a way to do this.

But for future reference the standard way an audio person would do this would be to create an audio bus* and put the reverb effect on it. Then send a proportion of the audio from the track to the bus using the Send slider. (You would normally want to set the send to be Post volume so that the amount being sent to the reverb effect would reduce or increase if you fade the track down or up.)

In the new Mixing Console view you can see this laid out as though you were using a real mixing desk with a reverb unit.

*Or you could use an Assignable Effect Chain instead of a bus but the procedure is the same.
