Paul... I don't know how to reply to your PM, or how to give you more information in support of my application to join the Facebook group. The only FB account I currently have is under the name Anan Isapta. If you will tell me how, I'll be happy to provide more background than is on that page. <s>

I have this problem solved. I record about 15 seconds of lip smacking before the actual audio.
I then export my audio to audacity and lower the volume on the lip smacking section.
Next, I use that lowered volume sample as the pattern for noise reduction.
Then I apply this to my whole audio file and it removes lip smacking and very faint tinkle sounds, leaving
essentially very clean audio. I'm beginning here with a Rhode lavaliere microphone.

Good to know that process works. In Theory it should. Noise Reduction attacks whatever you put in the Profile.

I've been able to help room echoes just a little by collecting echoes—by themselves—in a file and use that for Profile. That shouldn't work as well as it does. Someone will write a nice paper on what's happening there.

Two benefits :
#1: applying an equalization which selectively attenuates the resonant-frequencies of the room.
#2: the Noise reduction effect can act as an expander:
attenuating the reverb immediately after someone stops speaking,
(including between words, but not during words).

Rhode lavaliere
I count four of them. Which do you have?

I bought one for only 20 bucks for Microcenter.
It's a basic model.
I don't have the box anymore.
To be more exact, I do noise reduction in two steps:
1. First, static by picking up a sample and maxing out the settings on noise reduction.
2. Second, record 15 seconds of lip smacking and then lower that so it's very faint.
3. I then pick that up as the pattern and keep the settings under noise reduction maxed out, except for the volume reduction being set to only 10 or so.
4. So on the first pass I remove static and on the second pass I remove lip smacking.

Hello,

There are frequencies changes above 13k.
Can you remove the equalisation (Equalizer, Eq Curve for repair) you added in the script ?

The Eq Curve really change the sound quality.

This is a very old and very long forum topic. It might be better if you started a new topic and include a link to the "script" that you are referring to.
