Help Rrmoving echo with Vegas.

Hi All,
I need help removing echo from an interview shot in a "live"room.
I seem to recall Vegas and/or Sound Forge being able to do this.
Anybody (Spot??) have a step by step for this?
Any help is really appreciated .
Ken

What kind of echo? If it's just room ambience, you can use the Acoustic Mirror that comes with Forge. It's a convoluted verb, so you can sample the room echo, and apply it against the original with the phase inverted. It's a decent fix, but not perfect. I often use the multiband EQ to do this too, but it's sort of hard to do a step by step. Almost a novel. :-)
Can you send me a sample of the noise, maybe I can build you a veg file.

Sorry to be a nag but an echo is a *complete* repetition of a sound (think Grand Canyon)... A tail to a sound (what you're talking about) is called a reverb. Just thought you should know :)

Well...if we're gonna start tweaking semantics,(wich I hope we're not attempting to do, we all know what ken meant) a reverb is a diffused and multiple repeat of the original signal. during which the closely spaced repeats are at random and individual reflections cannot be distinguished.
An echo, by definition, may be a complete sound return, but also the perception of a non-diffused return of the original sound which may or may not contain the majority of original frequency information in the returned sound.
Therefore, a room or enclosed space may have echo and/or reverb, reverb only, or echo only.

Sorry Kevin. Im not trying to hijack this thread, it just seems like many people confuse reverb and echo :)

Here's what i've always learned:
Echo: Sound reflections delayed by 35ms or more that are perceived as discrete repetitions of the direct sound

Reverb: Multiple blended, random reflections of a sound wave after the sound source has ceased vibrating

What did you record with. How many mics. How many channels. What was your camera/sound setup?
