Spectral Gate/Expander with no artifacts

[sandandpaint]

https://www.ircamlab.com/products/p1680-TS2/ is excellent for setting an amplitude range for the FFT bins and suppressing everything outside that range

Spectralayers has a similar function tho only sets a threshold rather than a range

this might give you what you want tho i don't think it is fft based. Let's you divide the signal into 9 bands based on frequency and amplitude and then add fx to or change volume of those bands - https://www.effectgrid.com/

Spectral gating having never been achieved in an artifact free way, developers in 2025 seem to hover towards the technology of lookahead gating through AI, which seems much more reasonable and practical. As an exemple of this we could mention Noiseworks DynAssist which seems very promising.

There are none, I'm afraid. Audio artifacts caused by spectral gates are often a result of improper gate settings or the nature of the effect itself, particularly when dealing with signals containing a lot of noise or when using extreme settings. These artifacts can manifest as clicks, pops, or a general "smearing" or distortion of the audio. Spectral gates, which divide a signal into frequency bands and process them individually, can be particularly prone to creating these issues when the division or processing is abrupt or when the gate's parameters (attack, release, threshold) are not carefully adjusted.

Was that written by AI? It's a weird vague post.

Can you please address what is exactly weird - and exactly vague regarded to my post?

I don't owe you any of my time. Your previous post used AI, I'm pretty sure, and you didn't deny it. This is a one-sided, unfair conversation. Because I would be putting in effort and using up time from my real life that I can't get back. And you are copying and pasting (I think) the output from an AI prompt system.

But, I will reply, anyway.

This doesn't mean anything. "The nature of the effect itself" is not something useful to say when the premise of the sentence is explaining the nature of the effect. It's a circular reasoning. The English is written as a complete sentence, but it means nothing.

or when using extreme settings

Nobody asked about using it improperly.

These artifacts can manifest as clicks, pops, or a general "smearing" or distortion of the audio.

Clicks and pops are basically the same thing. You don't need to put quotation marks around "smearing." This is an audio forum with people talking about audio stuff.

And we know there are artifacts. That's what the premise of this thread is about. We don't need to be told that artifacts are artifacts. This doesn't mean anything. Nothing is being said.

Spectral gates, which divide a signal into frequency bands and process them individually

We were talking about both gates and expanders, not just gates. And we know what spectral gates/expanders are. We didn't need a second, redundant mini-summary of what a spectral effect is injected into the middle of the sentence.

Still nothing has been said so far in this post. It's all air.

can be particularly prone to creating these issues

That's the premise of this thread, yes. Thanks for saying it again. I guess.

when the division or processing is abrupt

Division? Did you mean frequency crossover? Nobody would call it a division, even though it does divide the frequency spectrum. They're called bands. But you might call it a division if you're mixing a giant pot of words together.

What does "processing is abrupt" mean? What?

or when the gate's parameters (attack, release, threshold) are not carefully adjusted.

Again with mentioning paramters but saying nothing about them. But wait, now you're saying that there *is* a spectral gate, somewhere, unnamed, that can be set to not have artifacts, if you adjust the parameters correctly? But you just said there aren't any without artifacts. So, uh, what?

Gee, you are essentially nitpicking and grasping at straws, while also attempting to twist and bend my words. But can you also address what is weird and vague about my op?

Which is it? My sub-sentence-by-sub-sentence addressing of your post was too nitpicking, or I didn't address your post?

[Sonic Illusions]

I rest my case

[tumface]

I rest my case

You have earned no self-congratulations. I was asking a very simple question. Your reply was self-contradictory, despite being only two sentences long. You said that I was nitpicking too much when addressing your post, but you also said I didn't address your post. It can't be both things. Sorry for repeating myself, since I'm just restating what I said in my previous post, but there's not much else for me to add.

What a great collection - and free!
the gate is much like the one in Spectralayers - the TS2 gate is better again

This could be a good choice, except it has a manual threshold procedure. Automation could partially solve this issue.

Bump up.

Any news on this?
