headsets are rubbish
Gamer headsets are rubbish. Mine is trash. Also see noise cancelling aircraft microphones. This is an entertainment quality microphone bought and installed originally for a presentation similar to a TED talk or a show such as the Apple Conference or DefCon Hacker show.

You know it's the real thing because it plugs in like this...

And the more expensive ones have connections for a radiopack you wear on your butt. Entirely wireless.
getting back to the topic at hand
If you don't change the capture (microphone) system, then everything else you do is going to be confusing, ticklish, unstable, hard to use, poor quality recovery. We're only on forum chapter 5. The longest message thread in forum history is by Ian who only wanted to read audiobooks in his apartment in Hollywood. 39 chapters.

So we have a ways to go.

Have you tried Audacity's limiter as a last step before exporting?
No I haven't. I have read that it's (and noise gate as well even more so) kind of a brute force thing that could in some cases do more harm than good. I felt I lacked the finesse to use it appropriately.

I recorded a few videos where I used regular Audacity compressor and raised floor from -40db to -30db and so far I'm happy with it. Breathing is occasionally still there but reduced substantially. Might have to re-adjust eq though as a side effect was it made the recording more bass-y oddly enough.

Koz is right that my recording area is bad but I'm trying to make lemonade out of lemons as moving is not currently an option.

Our Limiter is very good, I think.
It is gentle enough to keep distortion at a minimum.
I would personally like to have a noise floor setting integrated with it but this would of course complicate the GUI.

The apparent increase of bass is presumably a pseudo acoustic phenomenon. Increasing the volume makes the bass more perceivable proportionally than the mids, i.e. the equal loudness curve gets flatter, that's my sensation at least.

It is always a good idea to apply a high pass filter (at 80 to 120 Hz approx) before the compressor.
Chris' latest version has an option for perceptual compression, it works at least with the highs (bass was still an open problem).

I'm quite sure I did explain what the different settings were, especially in https://theaudacitytopodcast.com/tap005 ... eat-audio/.
Thanks Daniel for putting this right.
I was tempted to do it myself as I read about "the guy...".
Keep on doing great podcasts.

PS. As you're actually hosting the plug-in, is there any interest for improving it?
Nyquist plug-in integration has a bit improved over the last years and CC'Dc could benefit from some Version 4 features.
Especially the strange behaviour for selection beginnings (see Koz's comment above) is a major drawback.

Robert
Yes, I'd love to see it improved! I have moved onto Adobe Audition, but CDC is popular and I want people using a great tool Let me check on the license the software was originally released under and then talk to Chris's family about opening the source (if necessary). Feel free to email me so we can take this offline: feedback which is at TheAudacitytoPodcast.com .

This is version 1.2.7b1. Please note that it is an experimental, unfinished project. For production work I would recommend sticking with the 1.2.6 version, but this version has a permissive "free" license as detailed above.

Hi
i was wondering if someone could help me, i'm using audacity 2.1.2 on windows 7 64 bit and im using Chris's compressor 1.2.6.

i used it for the first time the other night and as soon as i ran it i saw the wave form change and listened to the results and it was perfect, but ive tried using it again and although it goes through the sequence the wave form doesn't change once its completed, and the resulting file seems the same.

i am using it on a WAV file as its got 6 channel sound, does anyone have any ideas for me to try?, i have tried uinstalling and reinstalling but its still the same :( #

Thanks

Pete

Chis famously doesn't like working with a sound track that starts with dead zero, flat line. When I'm cutting a show, I'll leave a little sound trash on the beginning to give Chris something to 'chew on'. After Chris finishes, I'll magnify my way in to the trash segment and cut it off or silence it. There's word that Chris doesn't like dead zero at the end, either, but jury's out on that one.

Reinstalling Audacity doesn't reset audacity. In Windows, you can choose to reset audacity during the reinstall by ticking an option.

Thanks for the Advice, I carried out the reset when I reinstalled it, but still no joy.
But can someone explain what the debug button does exactly? I tried it on this particular track and it came back with error messages.

Pete.

The debug button is intended for use by plug-in developers to show debugging information.
A few plug-ins abuse / re-purpose the debug button as a means of providing additional information for users, though this is not common (and not recommended).

If you copy and paste the debug information in your reply, it may give us a clue as to the problem.
