Question

How to remove big room reverb and flanging artifacts from smartphone video?

I've got a smartphone video of people taking turns speaking from a lecturn in a large, reverb-rich indoor space. The spoken words are barely intelligible, and I'm hoping to improve the quality. I'm hearing two severe issues throughout:

- Booming reverb/echoes
- A warbly flange/under water effect; I'm thinking is a compression artifact

Per helpful tutorials I've found online, I've played with Audition's DeReverb and tried minimizing echo by tweaking frequencies via Audition's parametric EQ, but the results are only marginally better.

I'm especially wondering if there's a tool that might help remediate the warbly flange effect?

Any suggestions for an amateur? Thanks.

Hi,

To start, please reply with a 30 sec or some sample of the audio you are having the problem with. 
Until we hear it,  it will be difficult to offer possible solutions. 

Best regards, Euan.

    Although I am most definitely NOT an expert user of AA, having listened to your sample I think the chances of doing anything even slightly successful to "improve" this audio are virtually nil, sorry!

     

    The "flange" effect very much resembles what is produced when effects like Noise Reduction are excessively applied to any audio.  Unfortunately, once this is "baked into" your file there is no way to reverse its effect.

     

    For the excessive reverb, again, although I have used a number of different "dereverb" tools, I know of none that would have any likelihood of any success with your file.
