de-essing |
|
|
audio pro's, i'm working with some audio-for video interviews with a lot of
sibilance. i have never done de-essing and i know there are specific
programs for this, but in the end is it easier to just use the parametric?

I suggest you use a program that has an edit window an write them out.

You can use the parametric, which will work sometimes.
A more powerful trick is to use the parametric to find where the sibilant
note is, then put the parametric into the sidechain of a compressor, with
it on full boost. This results in the audio being compressed a little
bit, with the exception of the sibilant note which is compressed a lot.
This tends to be more effective.
Most of the hardware de-essers are basically a compressor and a bandpass
filter that is adjustable. I assume the software does the same thing, but
you can just use an equalizer and compressor.
As always, better miking will eliminate the problem, but I know that is
not always possible.

I really like the little freeware de-esser from Digital Fish Phones called

No, the parametric will affect the audio all the time instead of just when the
sibilance is happening. A de-esser will affect the signal only when it's
threshold is crossed by high frequency content. A de-esser however will
probably not solve your problem completely, although it will help. My
experience with sibilance on video tape is that because saturation occurs at a
lower level with high frequencies, and lots of video audio is recorded at very
high levels, it has already caused distortion that the de-esser can't remove.

I'll second that (e)motion - that one is the best software de-esser I've
found, freeware or cashware. If anyone's got a better one, let me know!

It's even better if you apply it to only 4 or 5KHz and up, using Adobe
Audition's frequency space editing feature...

A proper de-esser is more than that. It needs to understand the level of the
"ess" in the context of the overall level of the recording by applying what
amounts to a threshold that tracks the broadband level of the input to the
frequency-dependent compression. I made the mistake of not doing this when
designing my first de-esser (Orban/Parasound 516E) ca. 1972. Hollywood
quickly gave me a schooling, and the subsequent 516EC (as well as succeeding
Orban de-essers) all had a program-level-tracking threshold.
Conceptually, the dbx de-essers work similarly, but instead use two
log-output rms detectors for the HF and broadband parts of the detector
sidechain. Subtracting the two outputs gives the log of the ratio between the
HF and broadband signals, which is used in a feedforward path, feeding a
classic dbx VCA to effect either broadband or HF-rolloff style de-essing at
the user's option.
Eliminating the broadband tracking part of a de-esser means that it will only
work correctly on compressed, level-controlled material and that its action
will be highly program-level-dependent otherwise. It's hard to lash together
a really effective de-esser using commonly available studio processors that
are not dedicated to the function. |
