STUBBORN THUMPS

Hello, and Happy 2020

 

 

In my editing of an audiobook, following the author's notes, I am instructed to remove "thumps" which I missed in my first pass.  It has taken me a while to even hear these, but I have finally found them and been able to isolate their sound print in the spectral view.

 

 

 

 

The problem is, I am not sure these are actual "noise" -- I can't seem to filter them out, and their signature in the spectral view shows more of a sound "hole" rather than a "thump."  Still, there is something noticeably wrong to the ears of the boss, and I am trying to figure out how to deal with it.

 

We do have the option of re-tracking these segments, but I would MUCH rather figure out how to correct these in Audition.

Can any of you hear the thump, under the word "lying" in the attached sample?   Any suggestions on how to fix it?

Thanks very much.


Rob

P.S.  I just found the related discussion, [https://community.adobe.com/t5/audition/unexplained-thumps-link-to-example/td-p/9998887] and I am trying the high pass filter as suggested in there by SteveG.  I will report back.

Tried that -- on my audio, the generic hi-pass filter knocks out a lot of the bass in the voice itself, so I am leery of using that.... may need to call in the audio surgeon.

Awkward one, that. Auto-heal won't touch it, but that's not really surprising, as this has frequency components that appear to modulate the sound itself and extend up towards 1kHz - which rather points to the mic or the preamp being overloaded slightly. Even if you could get it mostly out with RX (basically the heavy artillery) it probably wouldn't go out completely cleanly. If you want to know whether that would work, you'll have to wait until tomorrow - or try it yourself, of course...

Hmmm.

It sounds like a re-track to me. I wonder what caused it. There was some
concern (after the fact) that the mic was too close to the narrator; would
that translate to "the mic or the preamp being overloaded slightly,"
causing these artifacts?

I don't have RX -- but suspect it may be time to invest. Do you think I
could benefit from their RX 7 Standard Audio Restoration Software?


Thanks, as always, Steve.
