warehouse echo

[ernestserrano1966]

I recorded audio from a scene for a movie in a warehouse using a boom mic (Rode NGT 2) and on a Zoom H5. The audio person I used was not very good and now my audio has a strong echo throughout the recording. I have attached a link from my Dropbox as a sample. I would like to fix this in Audition if someone can explain how.

That's not an echo - that's actually reasonably clean reverberation (as far as I can tell on this laptop...) I boosted the gain and tried Audition's DeReverb on it with a pretty high setting, and it improves it a lot, although you'll never remove all of it, as it will have influenced the direct sound too.

Effects>Noise Reduction/Restoration>DeReverb is where you will find it.

The DeReverb seems to work but the gain option is not highlighted and so It will not allow me to use it. I just updated to cc2019 last night.

If it's the HUD on-screen gain control you're missing (that's what I used first) then you can enable it in View>Show HUD.

Should perhaps point out that if this had been an echo, it almost certainly wouldn't have worked so well - they can be nearly impossible to do anything about. Nice clean reverberation is much easier to deal with, though.

What you really need to do is find a better sound recordist, or train one up...
