I'm brand new to sampling, and have been inspired by eXT to use it's built-in sampler.

Of course, I'm getting a nasty click with the loops in a sample I'm trying to create.

What's the trick with getting rid of these?

Many thanks,

Fox

The trick is cutting the loop at zero crossings. This means that you make your cuts where the wave is crossing over the middle line. You usually have to zoom in all the way!
I usually also add a small fadeout. You can sometimes get by with a small fadeout alone, but it is always better to take the time and cut at zero crossings (some hosts have snap enabled for zero crossing- not sure about ext though).

The easiest way is to use an app that creates crossfaded loops (especially for stereo files which are nearly impossible otherwise). wavelab, soundforge, and some others do it...

If you feel like spending $40, Seamless Looper from Zero-X (http://www.beatcreator.com/) is very effective.

'Preciate the help. Seamless looper looks interesting.

I just tried extreme sample convertor for this and it blew me away.
it allows you to drag perfect loop points very easy.
i have used a few apps but i need to test this more but at this point the ease of clean loops was impressive

crossfading in apps like soundfore only work on certain files . I would not crossfade unless you can't get a loop by normal methods. but yes crossfading is needed on some sounds.

ya know THAT's right

I've not tried them all, but ESC is pretty user friendly. I've started tagteaming SF with ESC and its pretty quik work to put together some sharp sounding loops...

Any discontinuity in the waveform can cause a click (or thump or whatever). Zero crossing can be part of the solution, but not always. Even if you use zero-crossing, differences in the wave inclination before/after the crossing will cause the click. That's why in general you should look for the most similar possible waveforms before/after your loop points (including amplitudes). Crossfading is a trick to mask discontinuities but sometimes results in objectionable side-effects.

Looping is not an easy task for some very common sounds like voices, strings, effected pads, etc. I've been using Zero-X SL with some good results; it is worth the price IMO but will not solve all your looping problems. I need to check ESC for this (I've been using it for convertion only - very good app).

I agree that all of the afore-mentioned are handy utilities, but imo these utilities should not be used to mask the fact that one is still learning how to make loops. In the long run, you will be much better off if you first learn/experiment building your loops yourself. Once you gain a more intuitive understanding of how looping artifacts are generated, what technique serves the loop under different circumstances, you'll be in far more control of your music than you will by simply chasing the latest utilities and throwing cash at them.
