I have tried every pop/click remover i can find on the net.
None of them removes all pops/clicks i can hear with my ears.
They miss pops/clicks. And i can get it back very easy by boosting the treble.
It's 100% impossible to remove pops/clicks because there is too many variants of it. Some are lowpass filtered. Some are Highpass filtered. Some are bandpass filtered. Some are polyphonic. Some are in all frequencies. Some are short. Some are long. Some are modulated. Some are hidden. Some are random. Some are replacing the audio signal with a impulse. Some are reverbed. Some are fast repeating. Some are slow repeating.

No vst plugin knows how pops/clicks/crackles/dropouts/sutter/glitches sound in reality. The math has no ears. The function is deaf.

I can't have a real human remove pops/clicks manually. Zomming in into the waveform and correct each part step by step. It could take years to remove million pops/clicks.

I will give up on making music.

You may need to use a dedicated audio restoration tool like iZotope RX 2.

It make take several "passes" of a de-clicker, using different settings, to effectively remove all the noise.

Send me the offending track and I will run it through my restoration system.

You haven't mentioned which software you've tried that has failed.

Also (ignoring the esoteric reverberated and modulated noise) do you have a basic example that you can post?

I'm thinking that an automated algorithm may have trouble with more esoteric noise removal, IOW is it music (program material) or noise (garbage)? Sometimes the machine can't know.

You're a good man, Simon! There's also a $29 standalone version of basic tools by izotope, but I haven't had a chance to demo it yet. Here it is:

And I just wanted to chime in, Jedinhopy, that I have lots of issues with mouth noise myself, and have developed many tricks to get rid of it, but tbh, we hear a LOT more in front of our monitors or thru headphones than most people ever will in context.

Lots of those pops and clicks are normal parts of speech, and most folks don't even hear them until you point them out, so try to only deal with the worst cases and let the rest be. Getting rid of everything will sometimes give a synthetic quality to the voice as well. We're used to hearing some!

I use Avid's NoNoise which has a declicker/decrackler that you can adjust for various artifacts, but it takes a good bit of top end off, and some of the interpolated replacement audio sounds a bit watery, so a light touch and using as small a section as possible of the cleaned track is best.

Having golden ears is a blessing, but being aware of stuff like this is the price we pay!

It would be very interesting to try the new Acon Digital Studio Clean restoration suite on your track(s).

Here is the restored version:
https://dl.dropboxusercontent.com/u/775 ... e%20DC.ogg

I used the following process:
1. Converted original file from .ogg to .wav format (uncompressed)
2. Processed the file using the Declick module in iZotope RX 2 Advanced:
- 2 passes using the M-Band (periodic clicks) algorithm
3. Converted the corrected .wav back to .ogg format (compressed)

The restoration would be a lot more effective using a high-resolution (uncompressed) original.

The original seems to already have portions of that bubbly already-been-denoised artifact sound, or maybe it's been run thru a stereo center channel remover?

At any rate I agree that if it's possible to get a copy a generation closer to the original it would seem to be a job for Acon (they just came out with a new version), Izotope or Voxengo Redunoise.

Undoubtely

...and needless to say that the price seems very attractive

Judging by the demos samples, the rendering quality is honorable

I loved their vst pack back then and they had a really nice little known reverb also in it, and i used their restoration stuff with good success.. I guess it's an evolutionary update with cross platform support, and something i am definitely checking out.. I will need to demo it as i can not tell from the press release if it has a non fingerprint automatic denoiser mode.

Thanks a lot, Theo! In my humble opinion, Restoration Suite is quite i leap in terms of audio quality, so I hope you'll like it. And yes, the adaptive mode doesn't require a finger print. The adaptive mode usually works very well for speech and rhythmical source material. It might kill too much of the signal when processing slow orchestral string passages and similar, though. But, if the noise profile doesn't change too much over time, you always freeze the estimated profile. There is also a four band emphasis filter (low shelf, 2 peak filters and high shelf) that allows you to make modifications to the noise profile even with the adaptive mode activated.

The original poster said he would give up on making music because of the clicks. I want to know why he has them in the first place?
None of us using decent music making tools have any pops, clicks, etc. Now if you were restoring old audio files recorded from record players that would be a different story but then you'renot making music but only restoring it.

clicks during composing means: too much gain here and there, or bad quality base samples.

adobe audition's built-in restoration effects are great, the click and pop eliminator does the job well. usually i try to remove them by hand - drawing/editing the worst clicks out - if there are remaining clicks.

You should not make music if you hear clicks and then spend time and money trying to remove them. The quality of the audio in general will degrade and you may not be able to remove all clicks (plus it's annoying as hell making music while clicks are present).
Use a larger buffer size if the clicks are coming from latency issues.
Use less gain if the clicks are coming from improper gain staging.
You should not have ANY clicks or pops during music making. PERIOD.

It's impossible to remove pops/clicks/crackles/dropouts/sutter/glitches !
