Title: help w/ echo in recording... sample inside
Post by: andiunfold on September 19, 2007, 11:14:33 PM
Can anyone give me a little help with fixing a recording? We taped a show from the front row in a pretty empty college arena and there's a huge echo, among other things. Obviously I'm new to taping and could use some advice on how to fix this in any way. I'm using WaveLab 5.01 if anyone could help that'd be awesome!!
Thanks!

.... there's also a TON of shrieking throughout most of the tracks... is there anyway to cut back on that?

here's a sample track:

There's nothing that can be done to fix an echo IMO that is captured by room mics, and there is also not much that can be done with respect to proximate shrieking. 

If the shrieking is louder than the loudest peaks of the music, you could try a little compression, or a limiter, in post; all that would do, however, is reduce it a little bit relative to the rest of the music.  Screaming/shrieking from a human voice crosses over too many frequencies also corresponding to the instruments, so you cannot really EQ it without also negatively affecting everything else.

Andiunfold,

thank you sooo much! we were able to mess around with wavelab to remove a lot of the echo! not sure how we did it, but it's gone!!
i need a wavelab tutor.

Post a sample from the same section as linked in the first post for comparison's sake?  And share how you accomplished the differences?

Andiunfold,
You're welcome. I'm happy to help despite my little knowledge.
Take care ;D

Yes, I'm curious too.  To remove a lot of the echo, it must have been at only a very limited/specific frequency range that you were able to reduce with a notch filter, right?  What frequency range was it, and how did you EQ to reduce it?

Hello,

Well, what I did sugest is quite simple, nothing fancy, really. Andiunfold seems to be very happy with the results. I opened his sample with a 10 band equalizer. Then I reduced both 250 hz and 500 hz, just a bit. Also a smaller decrease on the 1kHz and a touch on the 2 upper frequencies to achieve more articulation.It's not perfect, honestly. But it sounds a lot better, more focused and tight. I haven't heard the whole processed file, but I'm sure it sounds OK.

honestly, i dont know what we did. i took the advice i was given, about the 10 band equalizer, messed with a couple things on wavelab and reduced the echo. i'll be more specific, but i'll have to take a look at the program. i'll upload some samples too in a little.  (just to re-stress, i'm a COMPLETE and UTTER newbie and really have no clue what i'm doing... hence the "i need a wavelab" tutor.)  ;D

*hopefully* i posted the right ones.  can anyone tell a difference? it all starts to sound the same after listening to the same track over and over again
