Title: SSSSibilance removal
Post by: beatkilla on December 05, 2011, 01:12:43 PM
I have a recording which has alot of sibilance.At first i thought it was the mics i had used but i checked an omni source and has the same issues,so i guess it was like that in the live performance.I've tried numerous ways to eliminate it but have no luck so far....even the most severe parametric changes have no effect on removing it.Any advice?This is not a multitrack so i am trying to lessen the effect on a stereo recording.

I don't have my source here with me to post a sample but as i said it appears to have been like that at the show.....here is a youtube video  i found of same show and as you can here there is a sibilance issue.....have a listen and is there any hope or not.

I'm sure this is a bit of a caveman solution compared to using a proper de-esser, but have you tried a simple light downward EQ in the affected frequencies?

The youtube video is just camera audio anyway, I guess, but wow, the treble is high.

Here's a 2 min sample of my recording  24 bit raw file.Let me know if there is any hope for this i have several de essers but you'll see what i mean.

Since you have several  de-esser programs and your not getting the results you want  I would use the above eq technique but use a notch on the eq.  Make it a very small notch and move it up and down the freq spectrum until you find the correct freq. you want to remove.  That should work for you and not alter any of the other freqs.

Just a clarification-

Since you have several  de-esser programs and your not getting the results you want  I would use the above eq technique but use a notch on the eq.  Make it a very small notch (by specifying a high Q value, which only effects a narrow range of frequencies, then boost the gain a lot) and move it up and down the freq spectrum until you find the correct freq. you want to remove...

Once you've homed in on the offending frequency range, keep the notch at that frequency but reduce the gain of the filter to a negative value to cut instead of boost that range and listen to hear if that works well enough.

That's the simplist and maybe least damaging option.

If you want to get more advanced, maybe because the above works and kills the sibilance but also does too much audible damage whenever the sibilance is not occurring, you can put that same high Q filter (boosted so the sibilance is super obvious and as isolated as possible) in front of the sidechain input of a compresser.  Set the compresser threshold so it engages only when the sibilance occurs and you've just made your own de-esser the old school way - the compresser will only engage when the sibilance occurs, but it will squash everything when it does.  Use the sidechain input of a multiband compressor instead, and only one band active which narrowly targets that frequency range and you're doing it the new school way - the compresser will only engage when the sibilance occurs, and when it does it will only affect that narrow frequency range.

My attempt.  Sorry, this is only an mp3.  Upload speed slower than a snail.
