cough removal
« on: June 04, 2007, 06:27:53 PM »
Hi there
I've been trying to remove loud coughs from my tapes for some time now--experimenting with software and plug-ins with both good and bad results, depending on the loudness, the spectrum and the time length of the cough/sneeze.
I've recently achieved fairly encouraging results for some types of coughs, yet not others. I would appreciate any feedback on the issue, as I've found little by searching the TS archive.
I usually process the coughs as follows:

1) spectrum analysis --> EQ and/or dynamics processis if the music spectrum is markedly different from the cough spectrum: that's the good case. Like music = bass and cough = shrill sneeze, or cough = throat sound and music = shrill high end.
2) if this fails, because music and cough have intersecting spectrums (usual case), I apply multiband compressor to the main frequency range of the cough, leaving other bands untouched. Unsatisfactory at best.
3) my new idea has been to try click and pop filters. I've had great results with the Audition2 filter even for loud, close coughs, yet only when the time length is short. The filter almost entirely rubs the cough away, sometimes replacing it with a characteristic 3kHz-5kHz metallic sound. This in turn can be EQ down or compressed.
I've given up on cutting and interpolating the missing bit (SF can do it well), except when the sound is very stable and for very short coughs.
Are there other methods around? I have no experience with the Steinberg apps, just Sony SF and Adobe Audition.

If you happen to be talking about between songs I would cut and cross fade. That would be the most effective. If the cough is anywhere on top of material you want to use though that would not work. I assume this is stealth stuff? Maybe you should bring cough drops or take smaller tokes to nip it in the bud.

This site is absolutely amazing.  Its like people read my mind!
I am asthmatic, and often can not suppress coughs throughout an entire show--especially when there is smoking or fog-machines in a venue.  I've often cringed hearing my own coughs at particularly inopportune times in my recordings, and wondered if there was anything I could do.
I'll be following this thread closely!

Yes cleantone this is stealth stuff for sure.
If it wasn't, the coughs would be too far to be heard...
It's not just my coughs though...rather other people's. When the music is loud, it isn't much of an issue, but with acoustic shows people coughing may be very annoying. Like near the end of a soft song, or when recording classical chamber music, or jazz piano, or even folk. With a crowdy audience it can spoil a whole tape!
