audio echo and hum
a story we have all experienced before…
I have a video with a professionally recorded VO track, then a few clips of people talking.
The VO track sounds great, as it was done professionally in a studio.But the clips of people talking, the client shot it themselves, and obviously it sounds terrible, echo since there was no sound dampening in a small room, audio hum. I actually think they used the camera’s built in mic!
I am not an audio guy, is this even fixable to get it to match the VO?
I would like to make any effort to help my client out, but if it is not possible, I’d rather not waste my time. -

[Tom Masters] “is this even fixable to get it to match the VO?”
Yes and No. Fixable to a certain degree i.e. you can make it “less bad”
Match the VO……. Probably impossible.
Try as Dave suggested with STP but just be careful you don’t do too much or it will sound like they are underwater.
For the reverb there are a few plug-ins available that may help a bit. Just google “de-reverb plug in” and take your pick. Some are free others have demos available. -
The hum is the camera if it was using the onboard mic. In PAL, that hum is exactly 150hz which you8 can safely notch out with a parametric EQ. Set the Q value to the highest (high numeric value = narrow notch) and reduce the gain by 20-30db. Hum will be gone.
Nothing gets rid of room reverb but again EQ notches around 120 and 240 hz can often help. Tune the resonances by adding gain and sweep the frequency up and down until you hear the resonance take off. The reduce gain to around -10db (to taste really). Reducing the reverb resonances helps to clarify the sound. It means it will never come close to matching the studio recording as you can’t add bass without making the reverb even muddier.

thanks to all.. The AVO really is perfect, an the SOT scary, so it seems like this time the client needs to learn a lesson on proper shoot setup.. or better yet, have it done professionally.
Unfortunately, thats not what they wanna hear.
