Editing a sample’s decay envelope

Which app is best for editing a sample’s decay envelope? Especially for snares etc. Nothing I have seems to do it well (I have Koala, iMPC, AudioShare etc).
Comments
BeatMaker 3 is really good for that, NanoStudio 2 also
👍
Sitala has a quite nice one-knob thing to shape the attack and decay of a sample.
Overkill here is Drambo, add a graphical envelope, a shot-sampler and an amp, set amp to 0, connect the amp knob to the graphical envelope and turn up modulation to the max and shape the graphical envelope to taste…
That’s interesting about Sitala. I remember looking at it before and concluding it didn’t do it, because it just had the one knob. Do you know how it works? Can it do the attack and decay separately?
The module you describe from Drambo sounds ideal, if I could just have that module on its own.
AAsamplePlayer has attack and release knobs and is just 1 dollar
Gadget has a couple of drum machines with sample decay options.
Nope, but 'negative' values on the knob apply a gradually exponential envelope ('curved' decay) while positive apply a log 2 linear curve for the attack. It's very musical and suits most use cases. The one-knob compressor is really good too...
Check the video on this page, it start by using the 'shape' knob and you can graphically see what happens.

There's a free desktop version (but it's a tad older than the iPad version) that will et you mess with the shape knob to get the feel for it.
Sitala is NOT a Sampler, it's a sample playback App/AUv3.
The last option is to 'process/edit' the samples until they are as desired and use the favorite sampler to play them back.
Welcome to the world of 'Lego Franken DAW' on iOS where a shedload of apps have to be used to cover for features missing in another
Sounds ideal!
😂
Great to know about the free desktop version. I’ll try that to see if I like what it does.
A transient shaper can do this, e.g. FAC Transient. But it also can add some latency.
I’ll check that out.
Seems to be displaying some buggy behaviour for me though - if I set the end time earlier then try to lengthen it again, it often seems to move the start point forward instead of the end. Anyone else? If so please email the dev, cheers
Ah, I hope that gets fixed. Can it export samples after you edit them?
No, that would be a good feature request > @looperboy said:
No, it's a very simple app but you could always put in a feature request
This is not a bug, was just chatting to the dev and the implementation is like this:
'The black screen is separated into two part equally, to control end point, you need to limit your drag point into the right part of the black screen.'
So basically dragging anywhere on the left half will adjust start point, dragging anywhere on the right half will adjust end point. Actually quite a good implementation, once you know about it! So this may indeed be the droid you're looking for!
Draw it with flux mini?
Also what is wrong with koala, just set the releas and record
Oh, that’s very good news! Thanks for the info. I’ll download that now.
I find “release” a bit strange in Koala. It’s very sudden. Is it a decay envelope exactly? And why is it called release? That in itself confused me initially because release usually effects what happens AFTER you let go of a pad or a key.
But yes, it sounds more like a noise gate to me rather than a decay envelope. You can’t really control the speed of the decay much. Or I can’t anyway. Am I using it wrong?
It is a release, is the envelope when you release your finger, thats why i was telling you to record it.
Set another pad to resample and tap the sample you want to modify qucikly and modify the release as you like. Then just crop the one you liked.
Ah, so it is! Now that I watch the editor i see what it’s doing. It’s really not any different from adjusting the end point of the sample though, is it? On drum hits anyway. You can’t control the speed the volume fades out at. With a decay envelope you can control what period of time it fades out over. This release parameter just seems to suddenly stop, on drum hits.
It changes the sound depending on whether you have One Shot turned on or not. Then it runs all the way to the end with a different sound, but it still doesn’t sound like a decay.
It is different than ajusting the end point because the release is gradual, but it only start when you let go of the pad.
The amount of release is the speed of the volume fade out AFTER YOU RELEASE THE PAD.
That's why I suggest to you to resample it so you can get th efade that you are looking for
I’ve been watching this thread and I get the feeling there is some confusion as to what “decay/release” entails. If you’re expecting a long decay/release from a short sample you need a sustain loop which may or may not work depending on the sample. Otherwise the maximum decay/release cannot be longer than the overall length of the sample.
Wel if you want it longer than the sample you can use velvet machine, but yeah I'm talking always about SHORTENING the sample
Agreed: we’re talking about shortening the sample. So when you talk about releasing the pad- does that mean One Shot has to be turned off, because when it’s turned on the point at which you release the pad makes no difference, but the setting of “release” DOES make a difference with One Shot turned on. Strangely, the more you turn up Release, the SHORTER the sound becomes.
With One Shot off, on snare drum hits, or kick hits, it works the way you describe. It’s a bit footery, as we say in Scotland, but it gets you there in the end.
yes you have to have one shot off, because one shot plays the whole sample.
It is footery, and that's why I recommend you resample your hits to another pad until you find the one you lie and crop it from the recording.
It sounds way more complicated of what it actually is xD
Thanks for all your help on this. I would just have discounted this function in Koala without your advice. I finally did what I should have done earlier and experimented using a sample of a sustained piano note. I can see exactly what it’s doing now, and your way of using it works perfectly. Thanks again 🙏
