...does anybody knows a way of filter out very short transients but keep the longer ones?

I‘ve made some audio samples and I realized that there are very short notes (1/32, 1/64 and shorter) which sound garbage...

Those audio files are all separated into instruments but I can’t record them again so my last hope is to filter out that very short transients...

since compressing could do the opposite effect, will DEcompress help my needs or is there even a specific plugin for this job?

 

What about using a Gate, like Pro-G or other? I think this is going to come down to your actual files what method you think is best. There are quite a few of them, most likely. But they are not all time dependent. This is why I mention this:

"Gates and compressors, like all dynamic processors, work specifically on the amplitude, or volume, of an audio signal—not the pitch." from https://blog.landr.com/noise-gates/

You could use hitpoint detection in a wave editor. Or something like WaveKnife which can chop silences. An Enveloper might work better in a time-dependent workflow. I think the answer is which is the least amount of manual work.

Mh, does a gate work with transients lengths or volume levels? I thought it would be the latter one?

How do I setup Pro-G for this and what other methods could be used?

 

Any "transient shaper" will do the trick, setting timing

If we're talking about super short transients which would sound more like a click of sorts, the classic ones are limiting, transient shaper, or some sort of clipping.

However...are we really? Because i'm not sure 1/32 or even 1/64 at common tempos count as "very short transient". Is there any way we can hear it?

 

Or even a screenshot of it in a wave editor. Also, how many files? It's condition or duration based processing .

Thank you. Here we go

 

Those transients are already non existing as far as I can tell. Maybe we're talking about different things?

I couldn't tell from your posts what exactly you want to do with those sounds. Do you want to keep them but flatten them more, or maybe you want to erase them completely? The latter would be a piece of cake and best done manually in an audio editor.

Here's one more idea: run a de-clicker plugin only on those parts to kill any transient that's left. Acon Digital Acoustica is perfect for that, but pretty much any de-clicker [or de-clipper] would do. You will get a smooth "texturised sound". I do a lot of editing like that and the results can sound awesome!

 

Thank you but is there any solution which can run in batch mode? I want to delete them completely

 

Do you mean clicks? iZotope de-click or any de-click tool should work. Or even a lowpass filter.

I would see about using Waveknife for this. But I think you would need to manually delete (or marker) the sections you want to remove first. Something you can batch, idk.

Sorry, editor cannot know which parts to delete so you will at least have to mark the regions. It seems like there are silent parts between them? If that's the case, maybe there is a way to mark them automatically and silence [not remove, obviously] them. Is there so many of them that you dread doing it manually?

 

I can imagine an approach where you'd do splits (with fade in/out) at those transients, something like split audio items at detected transients in Reaper...
that's probably de-clipping (at lower threshold) basically which iZotope RX does?

 

Thank you for the replies. Yes, it‘s a huge amount. Is there a chance to fade (not delete) them automatically? They sound like short notes play in old (and bad) soundfonts: the ending of short notes is sudden with no fade

 

So...not clicks? Just short notes?

Some DAWs will have some sort of transient detection which will "highltght" most transients and allow you to separate them, then if you select the ones that are problematic you should be able to lower the gain of those specific parts all at once, or even apply fades. Pretty sure you can do that on PT and Reaper, don't know about other daws. It won't add stuff where there isn't though, for that you may need to layer it with something else to serve as a "tail", maybe that's the main issue?

 

multiband distortion

 

some solutions sound overly complicated
pack them in a sampler and adjust ADSR (oh wow so manny slices, use Recycle or Ableton, render wav to midi function and adjust ADSR Globaly)
Or
Render/Splitt the parts on 2 differen tracks adjust with: if low - slight adjustment, Flux Bittersweet
If bigger adjustment: SPL Transient designeer

 

Wow. This is truly the community with the fastest users and by far best know how. Thank you so much for you answers!!!! I‘ve already learned a lot of your answers!

I think I described the problem badly... those records contain short notes which are choppy, they end suddenly (those notes are very short).

I tried to avoid this by putting reverb and delay fx on those files (they are also very dry). But even using heavily delays and reverbs lead to a noticeable harsh and sudden end of the notes. Sometimes the result is even a kind of click.

I had the brilliant (I mean stupid) idea to record several hundred midi files I programmed over the years to audio files while using borrowed hardware synths which I can‘t access anymore.

So what I am looking for is an automatic fx or batch job which can eliminate those short notes or smooth out their ends. What would you suggest?

 

Before talking about which tools to use, how would you describe which parts are to be removed and which to keep, just from seeing the waveform?
Your waveform screenshot markups look like it's going to be a tough job because some other parts of the audio look very similar.
