I anticipate using this, if I do, with "short" selections of say 5 to 20 ms but that's not under 1000 samples.

That depends on the sample rate. At the default 44100 Hz, 1000 samples is about 23 ms.

You are right, I wrote that before thinking.

I have made many changes and I think my work is at another stage worth sharing. But I will start a new thread to make sure I get people's attention.

I followed up the suggestion to use iterations of eq-band in my experiments today. Just constant gains on each interval, and a crossfading envelope. Mostly very pleasant results, and speed is not bad.

May next try (1) broadening the fix interval a bit to each side of the identified click, (2) using variable gain, (3) overcorrecting the clicks so they are a little bit below the background.

Just for those who may be looking for some basic help, I find it easy (though tedious) to remove high-pitched noises like mouth clicks with the low-pass filter set to 6dB/octave and 1000Hz. For low-pitched noises, like when a puff of air hits the mic, try the same settings on the high-pass filter. Many wet consonants can be removed by amplifying -10dB. You'll soon be able to distinguish clicks from wet consonants by ear.

I usually set the beginning and end of my edit to a zero crossing and do as narrow an edit as possible. Too long an edit will substantially change the quality of sound remaining, which is hard to fix.

As you gain experience doing voice acting, you can learn to hear many of your own problems and overcome some with practice. Often an immediate retake will help more than any amount of editing.

Even with much practice, it still takes me ten minutes to get a minute of clean audio. It would be VERY HELPFUL if somebody would come up with a mouth noise filter that would remove just the clicks and rumbles! :D

Indeed I did.

But you ain't seen nothing until you have the spectral editing tools of version 2.1.0 in your kit too.

Thanks! I downloaded the .ny file and put it in the addons folder so I can see it on my effects menu. In a few minutes I'll try it out.

I applied for the suggested Facebook group and am awaiting approval.

Using the default settings, I 'declickered' five minutes of narration, which took about 2'15" to run. The amount of work needed for click removal was reduced about 90% with no obvious effect on audio quality otherwise. I will certainly find this add-on useful, and MUCH PRAISE for the dev!

:D
