Hi!
I have a source material where there is a lot of silence, and eventually some short clicks, snaps, etc - very short sound events. I want to extract these and discard the silence somehow. Up until now I used the dynamic split in Reaper slicing at both gate-on and gate-off points. That works, but the issue is that then I have to render thousands of very small wav files, and use them in Max, and this is asking for trouble in many ways.
Is there a way to use the flucoma slicers so that they also report when a slice ends not just when they start? I am looking at fluid.bufampgate~ to mimic what I do with dynamic split, but I wonder how to get the gate-off times?
Or is there maybe a universal trick that can make this work with any of the slicers?
Thanks!!
If you silence level is consistent, then fluid.(buf)ampgate is a more customisable version of a similar thing that dynamic split is doing. Check the help file it gives a few examples of customisation like look-back and look-ahead to capture tails for instance or time hysteresis, as well as the usual thresholding, etc
Argh. I missed the fact that bufampgate~ outputs 2 channels with the 2nd being the gate-off points. Sorry for the noob post!
Yeah, fluid.ampgate~ is great for this. Once slight bummer with fluid.ampgate~ vs fluid.ampslice~ is that you no longer have the relative envelopes. So you have to rely on absolute thresholds, which are great for some stuff, but not others.
but your ramps are wayyyyyy too quick (these are in sample you know) so on real signal you’ll need to have a little more smoothness. The drums examples are good to see that.
Yeah I know, this is just a “very didactic” (and otherwise useless) example I made for myself. I wanted the points to go exactly at the start and end (for visual satisfaction, and because of ocd), that’s why the ramps are 1. But I’ll set up a slicer patch for some real-world signal soon. :))
Yeah, good point! I actually only need this for silence removal (something like the dynamic split in reaper), for that it must be perfect.
Actually you still have them: you just need 2 passes if you want on/off and then cut the slices further with the relative object (which also has a floor). Have fun with a similar toy example with ampslice and you’ll discover a fantastic detrender.
By this do you mean running them in parallel and then filtering one set by the others? From what I remember (it’s been a while since I mess with these) was that I couldn’t have fluid.ampslice~ behavior and “offs” from the same onsets.
I meant in his case, which is offline, so in series: you create slices with ons and offs, then you can see if they will subdivide with detrending.
