Adui Noise reduction question

Headphones: Sony MDR-7506

WHile doing Noise reduction I some times hear odd clicking sounds when the subjects are speaking.
Mailnly when they use words that Rhyme with "Hick" "Yuck" or basically any words that have a sharp sound
This isn't a constant clicking throughout a scene but a little click durring some words that changes when I replay it.
But I only hear it with my head phones and not on my Speakers.

I was starting to wonder if maybe i am using the noise reduction too much, like blasting it all the way up 100% reduction and it's causing that odd sound. ( any takers on that theory?)

Either way. Any advice? should I leave it as is? Any one have the same issues?

UPDATE

Don't think it's a head phone issue but i messed with the noise back and fourth and it seems that every time i mess with the noise that's when I get that odd sound. If I leave the clip unedited it isn't there
Any ideas?

"Cheap" noise reduction can induce audio artifacts. This is why professional rerecording mixers - who admittedly have a lot more horsepower available than you do - use several (very expensive, CPU intensive) NR plugs-ins simultaneously. You can "print" (record onto a new channel) the NR dialog to conserve CPU usage before you mix. Do several "gentle" passes instead of trying to brute force it all at once. Do Rumble on one pass, Hiss on the next, then go after the Hum... you get the idea. Continuously refer to the original to keep your perspective. Keep checking sync, sometimes NR plug-ins induce delay when you print, so you may have to nudge the audio back into sync.

Don't worry about noise reduction too much until you are ready to mix. Get all the pieces in place; you may not have to do as much NR as you think.

I agree with Alcove. All NR software/hardware introduces artefacts and the cheaper ones introduce more artefacts and sooner than the expensive NR units. However, the symptom you describe is not one commonly associated with a NR artefact. It could be that the symptom you describe was there all along but masked to an extent by the noise, so reducing the noise makes the problem more noticeable.

The symptom you describe is more indicative of a mic positioning problem, what is called a "plosive" and the letter "K" at the end of a word is a plosive. Some EQ and rebalancing of just the letter "k" will probably solve your problem. Having never used the Adui NR, I can't be certain that your problem is a plosive issue rather than caused by the NR.

So you're saying there's a frequency representative of the 'k' sound and that that frequency should be reduced with the EQ?

I was actually using spectral repair for virtually everything, like de-breathing, and the tongue sounds. Now I've discovered the 'de-breath' function.

Also I've been putting a high pass and low pass on everything.
Also I'm liking the compressor and limiter more and more, and the leveler less and less.
And I've fallen in love with reverb. I'm bloody smitten.
And I guess I'm liking the EQ somewhat. I suppose I could make things sound more or less bassy or full, but I like all of the sounds after EQ adjustments near the ends. I don't understand why one sound is better than the other. They're different. But I don't understand why the different sounds are better or worse. Yet.

Don't mean to hijack your thread Mr. Pink. Just getting my fair share of the Expert advice. Hope you'll excuse the indulgence. :)

ALright guys here's what's up. Two things
1.
I Made the audio clip into a small file to send it off to have a dude on here look at it.
Thing is, when I played it back, the odd noise I was talking about was gone. Maybe when I rendered it, it did something?

2. While playing back the original file for comparison the noise would sometimes be there and some times not be there (without me doing any other effects on it other than what I had already done to it.
I don't know what to make of it. very weird.

Not exactly. Plosive consonants (p, b, t, k) are produced by stopping the airflow with the tongue or lips and then releasing the built up air pressure. If a mic is too close to the mouth and/or directly in line with the airflow, it can in effect overreact to these plosive consonants, similar to how an unshielded mic will overreact to even a very light breeze. Particularly with p, b and k, if the mic is inappropriately positioned, there is likely to be a much higher concentration of low frequency content and with a "k" there can also sometimes be a click like sound, more concentrated in the mid frequencies. The best solution, other than avoiding it in the first place, is usually some combination of EQ and gain reduction on the plosive.

Which would imply the issue is outside the frequency response of your speakers but not your headphones, IE., in the low frequencies. Alternatively, the issue could be in a frequency range within the response range of your speakers but hidden by the acoustics of your room. These are just two likely guesses, there are potentially various causes and various reasons why you only hear the issue in your headphones and I would need to examine the files
before I could be sure of the cause/reason.
