Echo
 

I have a slight echo in some of my audio clips of an interview. What is the best way to reduce the echo with FCSP?? I'm not that great with audio so detailed instruction is appreciated!! Thanks.

Sadly, there's no such thing as a 'de-verb' filter. The only sure-fire way to remove echo is to not record it in the first place. (Not helping, I know.)

yep, that seems to be the consensus. Fortunately it really isnt all that bad. Next time I will prevent it.

There are some ways to kind of handle it, but they can get pretty knowledge intensive.

One thing that can really help is you can analyze the room using a frequency analyzer . Easiest way to do this is find a lot of places where the talking stops and make cuts DIRECTLY after this. This should give you a place with almost only reverb. Stack a bunch of the only reverbs next to eachother and then loop it. Look at the analyzer and find the room's main frequencies and cut those out completely.

Then, depending on the dimensions of the room, cut the low-mids or lows a bit (the bigger the room, the lower the frequency, just listen for it). Also, always run a high pass filter on everything, even if it's a really low frequency like 30-60 Hz.

Now, depending on the size of the person and whether it's a male or female, do a broad boost somewhere between 2.5k-8k since this is the speech clarity region. This way you can turn the volume down a bit and still understand the speaking.

If that doesn't do enough, automate the EQ or even use a dynamic EQ.





However, all of this still won't sound perfect. If you can re-record, do it. If you can't, this should help a bit.

Get the mic as close to the subject as possible. That'll help stop the sound from picking up reflections. That's why a lav is usually best for talking head type shots.
