How, if there is a way, can I fix an echo-y room audio recording?! I recorded video off of a DSLR camera and the audio was recorded separately, but I have somehow lost the audio so I am trying to salvage the video recordings by using the audio recorded from the back of the camera. Is there ANY WAY to fix this?! Thank you!
Very unlikely I'm afraid. Getting rid of reverberating room acoustic is virtually impossible. There are some apps that purport to be able to 'De-Reverb' but they don't work very well on speech and are rather expensive.
In my experience, De-reverb tends to make things worse, not better...
Agreed. Every deverb programme I've heard does little to help the room echo but also adds a ton of nasty artifacts.
I'm afraid the only solution to this is to not use the on-board camera mics for anything other than general atmosphere. Any time you record a voice, you need a separate mic as close to the speaker as possible. Thats why you see so many lavalier mics or sound recordists with a fishpole on professional stuff.
The OP did have a separate audio recording Bob but mislaid it.
In case it's useful to someone else with this problem, I find it can help to take out bass frequencies, and boost presence ones [say around 3kHz]. You can't [as stated] remove the loose acoustic but you can make the [speech] audio more intelligable.
