Auto finding sustaining loops in samples ?

[Yekuku]

HI there ,
I have been doing this all these years manually and I am looking for a software that can do this for me , automatically.
I have been told that , Zero X Seamless looper and Antares Infinity used to work good, but both software are long gone.
Do you know of any new software that can do this with good results ?
Thanks

I am not sure WHAT you are sampling but if it's your own synths then:

1: You might want to take a look a SampleRobot. It has a feature called WaveRobot that will find loops automatically. I have never used this software so don't ask me about it. I just read what it does.

2: Sample your material on the F3 tuned to -23cents. This will give you single cycle loops of 256samples. Transposing octaves up or down will give you the relative size (1 down 512samples; 2 up 64samples) of the single cycle.

I hope this helps.

What sampler are use using?

So essentially, if you have a synthesizer with a controll for tuning in cents, you transpose your patch down 23 cents, and then sampler he f3? Excellent idea!

Autosampler in GarageBand can do this too. It's a scaled down version of Redmatica. I used it do build my sample packs. It takes a bit of setting up, and you might have to tweak stuff later, but it makes the job much easier than it was in hardware sampler days.

It's strange that Kontakt doesn't do autolooping. Do any of the other soft samplers do it?

I don't think Maschine or short circuit do, but I'll explore them the next time I boot them up. The s2000's has a pretty decent auto loop feature, but I think it needs the right kind of sample, and it probably helps if you already have an idea of what the loop should be to start off with!

Yes.

I learned this by working with the Ensoniq EPS-16 Plus and creating wavetables for this machine. The EPS-16 Plus in particular is very picky when you want to work with home-made transwaves. It works best (needs) single cycle loops of 256samples.

F key -23 cents does the trick.

FYI:
F2 -23 = 512samples; F3 -23 = 256 samples; F4 -23 = 128samples; F5 -23 = 64samples; F6 -23 = 32samples.

I am not sampling anything actually, I am building a personal sample library from sounds that I have made the last 20 years, most of them evolving atmospheres and SFX. I have quite a few hardware samplers so hopefully it will end up being in AKAI/Roland/Kurrzweil/EMU/Ensoniq format
What I am looking for, is a software that will automatically offer me a few alternative sustaining loops, let me choose / edit the section I want and save it as a Wav along with the sustaining metadata. Nothing fancy really, just some of the early nineties technology.
I havent used waverobot but i will check it out.


Nice tip about sampling, thanks for sharing.

Hmm, it seems that Redmatica has been around for over a decade but I never heard of it.
It looks similar to Samplerobot, I will give this a try too.

The s2000's has a pretty decent auto loop feature, but I think it needs the right kind of sample, and it probably helps if you already have an idea of what the loop should be to start off with!

the s2000 was my first sampler, it had some cool features

I checked the math behind the above claim and first of all, it checks out.
For completeness I would like to add that the above is for sampling frequencies like 44.1 kHz and 88.2 kHz.
If you want to do the same for 48, 96 or 192, (12 anyone?) kHz you should use F# +23 cents.

p.s. if I recall correctly, the discontinued Creative/E-mu Emulator X3 had excellent auto loop capabilities.

AKAI/Roland/Kurrzweil/EMU/Ensoniq format

Each of those machines have auto-looping onboard. If you want to create multiple formats then you're looking at a combination of Redmatica KeyMap (unobtainium) and Chicken Systems Translator.

some of the early nineties technology.

Antares Infinity fits the bill . It is still possible to buy this if you have an OS9 Mac or Sheepshaver to run it on. It doesn't batch loop though, whereas KeyMap does.

[rant]To be fair it is possible to find fairly good loops with Kontakt as it stands, but you have to work on each sample manually, looking for the points yourself, there's no batch processing, and it can't do guaranteed perfect loops every time like Redmatica or Infinity can. And you can't adjust the loop in real time which is really retarded. Literally. You have to re-trigger the sample each time. So it takes longer than it could. Kontakt has issues importing loops from Emu samplers- you have to tell it to "load loops from sample" for each program (but not each sample).[/rant]

Basically- no one seems to need/ want good sustain loops any more. We just use really long samples instead.
