can you remove an echo from audio in FCPHD
Hi, I was just wondering if you could really do anything about an echo during an interview I shot. I just wanted to tone it down a bit if possible…does anyone know how to do this in FCPHD?
Thanks!!!

More importantly, how do we remove this repeating echo of posts from you. 🙂
Go into Audio filters/FCP Filters, that’s where things like Expander/Noise Gate are. Try typing Noise gate
in the help section, it’s all there.

Oh great! An Admin removed the repeated posts from Amy, now nobody will get my
little joke! I’ll have to laugh all by myself 🙂

She was clearly having quite an echo problem. I got your joke…

You can try using the 3-band equalizer filter to help get it under control.
The most offending part of the echo probably occurs in a particular frequency band, so one way to do this is to boost the midrange, then carefully sweep through different midrange frequencies until the echo gets to be at its MOST annoying level.
That’s the easiest way to identify the frequency of the echo or reverb. To fix it, keep the midrange frequency at that setting, then turn down the level for that frequency until the problem is less annoying. You won’t be able to get rid of the problem, but it might become less apparent. Keep in mind that you might also adversely affect the quality of the audio source as well. So it’s a tradeoff.
For future reference, always get the microphone as close as possible to the sound source. Use a lav mic or a cardioid mic. Shotgun mics will pick up a lot of ambient from the rear of the mic (most shotguns have a “bi-polar” pickup pattern) and aren’t as good at isolating a source as a cardioid in a closed room.

I might sound odd, but I have had some luck activating the echo filter and then putting all echo controls to the left (off).

Guys,
I can’t sit here and view all these replies telling Amy that she CAN cure bad audio with simple filters.
Sorry, but here come the harsh facts.Reverb is one of the most IMPOSSIBLE-to-fix of audio problems (second only to severely CLIPPED levels).
EQ won’t do it.
Its reverb (repetition) of the PRIMARY audio… the same frequency that you WANT to KEEP.The Noise Gate is probably the best choice, but it will PUMP if its set high enough to be effective on the reverb.
Whatever you try will adversely affect the overall QUALITY of the audio being “fixed” and be very noticeable to the listener (especially compared to any “good” audio in the same production).
The phrase is: “GOOD audio is the absence of BAD audio.”
Therefore the best cure for BAD audio… is recording GOOD audio.
That’s why major motion pictures and many TV shows LOOP (replace with ADR) their “bad” location audio with the actors re-recording the dialogue in a quiet studio.

“Its reverb (repetition) of the PRIMARY audio… the same frequency that you WANT to KEEP.”
Some rooms reverberate at a particular frequency and cutting back at that point can help solve the problem. I’ve tried it and it can be of some help.
It’s not a cure-all, but it makes the problem less annoying and might make what’s being said a little more intelligible.
Sometimes it’s not possible to re-record and you just gotta go with what you got. Making use of the tools at hand is the best that can be done under certain circumstances.

One more thing about using a filter like Noise Gate: If you have some room noise, put that behind the dialogue. It will help smooth out
the transition between gate and echo.
