How to chop samples
Chopping a sample is three decisions: what to cut, where to cut it, and what order to play it back in. Everything else is which software you happen to have open. Here is the technique, then the exact steps in the places people usually do it.

Chopping a sample in three moves
Find the pieces
Listen through once and note where a new hit or a new chord starts. Those are your cut points — not the bar lines.
Cut just before the transient
Place each cut a hair early, on a zero crossing if you can see one. On the hit is too late; the attack is what makes it sound like a hit.
Play it back in a new order
Put the chops on pads and play them. The rearrangement is the flip — a chop you never reorder is just an edit.
Technique
Where to put the cut
The instinct is to cut on the grid. Resist it. A break does not change on the bar line, it changes on the hit — and a soul loop does not change every two bars, it changes when the chord does. Cut where the music changes and the chops stay musical when you move them around; cut on the grid and you get sixteen slices that only work in the order they came in.
Within a hit, place the cut a few milliseconds before the attack. The transient is the part your ear uses to identify a drum, so a slice that starts after it sounds soft and late no matter how hard you hit the pad. Zoom in far enough that individual cycles are visible and you will also see where the waveform crosses zero — a cut there is a cut that will not click.
One more thing that is not obvious until someone says it: chop more than you keep. Make every cut the material suggests, play them all, and throw out everything that does not earn a pad. A flip built from four strong chops nearly always beats one built from sixteen adequate ones.
Technique
How to stop chops from clicking
A click at the start of a chop is not a bad sample, it is arithmetic: playback jumps from silence straight to whatever value the waveform happened to be at, and that vertical jump is an audible tick. Two fixes, both cheap. Move the cut point to a zero crossing, or put a very short fade — one to five milliseconds — on the start and end of each slice. Most samplers can do the second one per pad, which is faster than nudging twenty cut points by hand.
The same applies to the tail. A chop that ends abruptly mid-decay clicks on release, so either cut at the next zero crossing or let the pad's release envelope do the fade for you.

How to chop samples without a DAW
This is the fastest route, and the one worth learning on: no install, no project, no plugin. Open the sample chopper, drag the audio onto the waveform, add a chop marker at each hit, and press Load chops in TAIL — the slices land on sixteen pads in order and you can play the flip immediately, in the same tab. Or just download them as files and take them anywhere.
Everything decodes locally on your own device, so nothing is uploaded and there is no queue. The technique is identical to the DAW routes below; you are just skipping the twenty minutes of setup that sit between an idea and hearing it.
In a DAW
How to chop samples in FL Studio
The dedicated tool is Slicex: drop the audio in and it detects transients and maps each slice to its own key, so you can play the chops from a keyboard or the piano roll straight away. Drag the slice markers if the detection lands them in the wrong place.
Fruity Slicer is the simpler sibling — beat-slicing with fewer options, which is often what you want for a straight break. And Edison is the manual route: select a region in the editor, and drag the selection straight out onto a channel or into a sampler as its own sound. Use Edison when the material is loose enough that transient detection guesses wrong.

How to chop samples in Ableton Live
Drop the audio onto a track, right-click the clip and choose Slice to New MIDI Track. Live asks how to divide it — by transients or by a beat division — and then builds a Drum Rack with every slice on its own pad, plus a MIDI clip that plays them back in the original order. Deleting and reordering notes in that clip is the flip.
For finer control, load the sample into Simpler and switch it to Slice mode, where you can add, remove and drag slice markers by hand. Either way, adjust the attack and release envelopes if the chops click.

How to chop samples in GarageBand
GarageBand has no transient slicer, so it is manual: put the playhead where the cut belongs and split the region (Edit → Split Regions at Playhead, or ⌘T on a Mac), then drag the pieces where you want them. It is slower than a real slicer, but for four or five chops out of a loop it is perfectly workable.
On iOS, GarageBand's Sampler lets you record or import a sound and play it back across the keyboard, which covers the play-it-in-a-new-order half of the job once you have your pieces.

How to chop samples in BandLab
In the BandLab editor, split the audio clip at each cut point from the clip's own menu, then move the resulting clips around on the timeline. For pad-style playback, load the pieces into BandLab's sampler instrument instead and trigger them from the grid.
Since BandLab already runs in a browser, the honest comparison is with a browser chopper: the chopper here skips the account and the project, and hands you the slices as files as well as on pads.
Material
What to chop
Drum breaks are the classic: cut at every hit and you own a kit made from a record. Soul, jazz and library records are the melodic counterpart — chop on the chord changes and a four-bar loop becomes a progression you wrote. Vocals chop into syllables that play like an instrument. And your own material — a voice memo, a bounce, a field recording — is the one category that is always yours to release.
Which is worth saying plainly: chopping does not clear anything. A recognisable piece of someone else's recording needs permission however finely it is sliced. Practise on whatever you like; release on material you have the rights to.

Common questions about chopping samples
Load the audio into something that can cut it, place a cut at every point where a new hit or chord begins, export the pieces as separate files, and play them back in a different order on pads or keys. The rearranging is the part that matters — cutting alone is just trimming.
A few milliseconds before the transient, ideally where the waveform crosses zero. Cutting on the transient shaves off the attack and makes the chop sound soft; cutting well before it leaves silence at the front and the chop feels late when you play it.
Because the slice begins mid-waveform, so playback jumps from silence to a non-zero value. Fix it by moving the cut to a zero crossing, or by putting a one- to five-millisecond fade on the start of each slice.
As many as there are distinct events, then throw most away. Sixteen is a practical ceiling because that is one bank of pads, and a flip built out of four good chops usually beats one built out of sixteen mediocre ones.
Chopping does not clear a sample. Using a recognisable piece of someone else's recording in a release needs permission from the rights holders, however finely it is cut — the idea that a short enough chop is automatically safe is a myth. Your own recordings, royalty-free packs and public-domain material are yours to chop freely.
Chop something in a browser first. You skip installing a DAW, creating a project and loading a sampler, which is where most people lose the idea — and the technique you learn transfers to any DAW unchanged.
