Audacity 2.1.1
Windows 8.1 x64
Hello everyone.
I'm trying to get rid of noise in a song. The song is called "The Words We Use - Building Coral Castle". The problem is, even the real version from the album (I bought it) as well as the official YouTube version have that noise "effect".

2:36 - 3:10
I also attached a little sample.
Oh yeah and a little side note:
I followed this guide, but when making the selection and exporting, it still exports the whole track and not only the selection.
How is this noise called and how to remove it?

Re: How is this noise called and how to remove it?
You should be able to drag-select a portion of the show and File > Export Selected Audio. Only the selected audio should go. Audacity has two different Export tools. It doesn't change identity like some other programs.
That's clipping or channel overload. The blue waves are not high enough up for actual clipping, so the performance was clipped before (or maybe during) post production. Simple version: the sound got so loud that the digital signal ran out of numbers and just stopped increasing. It doesn't look like actual clipping (dead flat tops) because any production, filtering, effects, etc, will change the shape of the waves; another vote for the damage happening very early in the authoring process.
In general clipping sounds terrible and it's permanent. Number two.
The Four Horsemen of Audio Recording (reliable, time-tested ways to kill your show)
-- 1. Echoes and room reverberation (Don't record the show in your mum's kitchen.)
-- 2. Overload and Clipping (Sound that's recorded too loud is permanently trashed.)
-- 3. Compression Damage (Never do production in MP3.)
-- 4. Background Sound (Don't leave the TV on in the next room.)
There is one tool called Effect > ClipFix. What that does is try to guess what the sound would have been had the signal been allowed to continue upward. Is that enough soft-fuzzy English words? You can never put the original performance back. It doesn't exist any more. But you can hope to make it a little less annoying to hear.

Paul-L's De-Clicker plugin can remove some of the buzz , see attached before-after ...genbarrison wrote:... The problem is, even the real version from the album (I bought it) as well as the official YouTube version have that noise "effect". https://youtu.be/UKU1TMUvf3s?t=156 2:36 - 3:10

Thanks for the helpful answers.Trebor wrote:Paul-L's De-Clicker plugin can remove some of the buzz , see attached before-after ...genbarrison wrote:...

I downloaded Trebors sample and I really like the result. However, I have problems achieving the same result. Could you please tell me which settings you used in the Paul-L De-Clicker plugin?
Alternatively, here's the full part of the track that needs the fix: https://www.sendspace.com/file/txl0co
I'll keep trying around.

Thanks again.
I wasn't able to get rid of all the overload, but it's definitely better now.
