Problem with my Ssss (sample recording included)

Post by aussiesound » Tue Jan 18, 2011 2:07 am

Hi guys.

Would anyone with more experience kindly tell me what to do to reduce the S on my recordings? They're too sharp, or to loud, I don't know the exact term but they're clearly annoying to the listener.

"In order to maxssssmize the ssssound quality... "

I've attached a sample of my reading. I'm using a condenser mic with a pop filter, and I'm about 10min away from the microphone.

Best,

Leo

To remove this sss (sibilance) is called de-essing. There are de-esser plug-ins, (including Spitfish which is free).

However de-essing can be crudely done using equalization: by putting broad notches around 4KHz and 8Kz (approx) ...

Have a look at the frequency analysis of the sss on its own, note any big peaks 4KHz and above, then use the equalizer to reduce these peaks, (they are the shssh sound).

BTW if you are going to install Spitfish or any other VST plug-ins, use the latest version of Audacity: 1.3 (not 1.2).

BTW2 you are too close to the mic which is causing some distortion.

Spitfish does a better job than equalization: it only applies the filter when sibilance is detected ...
