How do I preview one chip without downloading everything?

Each chip has its own play control, and starting one stops whatever was already playing, so you always hear a single piece rather than an overlap. Nothing is written to disk until a download control is used.

Why do the chips click at their edges?

Because each chip begins and ends wherever the fixed slice length falls, which is rarely a zero crossing of the waveform. Playing a chip on its own starts and stops at a non-zero level, and that step is heard as a click. A very short fade at each end in the sampler removes it.

Is the last chip shorter?

Yes, if the file's length is not an exact multiple of the slice length. The tool steps through in fixed increments and the final piece contains whatever remains, which is the honest result rather than padding with silence.

Can I chop on the beat?

Only by setting the slice length to match the tempo by hand: at one hundred and twenty beats per minute a sixteenth note is an eighth of a second. The tool itself reads no tempo or transient information, so alignment is a matter of choosing the right slice length.

Are the chips lossless?

They are copies of the decoded source written as sixteen bit WAV, so they contain no further lossy encoding and no filtering. The only losslessness caveat is the decoding step itself, which happens before any chopping.

Sample Chopper cuts a file into evenly spaced pieces and lets you hear each one before deciding to keep it. It is the slicing workflow built for someone about to load the pieces into something else.

What is Sample Chopper?

Choose a file, set the slice length, and the file is divided and listed. Every chip can be played in place and downloaded separately, so the pieces you do not want are simply not taken.

The controls and the result:

A file chooser that accepts a drop or a click to browse.
A slice length from a tenth of a second to four seconds, with a twentieth-second step, defaulting to half a second.
A count and a hint line explaining that the play control auditions a chip and the download control keeps it.
One tile per chip showing its number and its start and end times in seconds, with a play control and a download named from the source.

Slicing uses the fixed-length rule: the slice length is multiplied by the sample rate and rounded to give a sample count, and the file is stepped through in that increment, with a final piece that is shorter because the material ends. Because the same sample count drives both the boundaries and the audio each chip receives, the pieces are exact and contiguous rather than approximated from a floating-point time. Each chip is then encoded once as a sixteen bit WAV and held as an object URL, so downloading one costs nothing beyond the bytes; the pieces are also prepared as audio buffers, which is what lets the play control audition a chip immediately without decoding anything again. The workflow the tool is built around is audition and then keep: play a chip to hear whether it is worth taking, and download only the ones that are. Because the slice length drives both the boundaries and the audio each chip receives, the pieces are contiguous with no gaps or overlaps, which is exactly the property a sampler needs when it assumes evenly spaced slots. Auditioning one chip stops any chip still playing, so there is never a question about which sound is being heard.

What the chopper does not do:

No transient detection, so a chop can land anywhere rather than on a hit.
No fade at the chip edges, so a chip cut through a loud sample can click when played alone.
Fixed spacing only; the pieces are all the same length except the last.
No tempo or bar alignment, so chops do not automatically line up with a grid.
No reordering or re-export of a rearranged sequence; the chips come out in source order.
Every chip is mono or stereo as the source was, and always WAV.

Use it when a loop or a break needs dividing into pieces to trigger or edit elsewhere: chopping a drum break into sixteenths, cutting a vocal phrase into syllables, or preparing a sample library where the pieces need auditioning before they are chosen. When the division should be a count of equal parts rather than a fixed length, the slicer offers both modes, and when the whole file should be exported as one continuous piece rather than many, the trimmer and cutter work on the file as a whole.

How to use Sample Chopper

Drop or choose an audio file to chop.
Set the slice length, using a shorter value for finer chops.
Play individual chips to audition them, with the play control stopping whatever was sounding.
Download the chips you want to keep, named after the source and numbered.

When to use Sample Chopper vs related tools

Sample Chopper is the audition-first slicer, so it suits someone choosing which pieces of a break or phrase to keep. Audio Slicer divides by a part count or a fixed length and exports everything, and Audio Splitter cuts where the audio is quiet instead of on a fixed grid. When the piece being chopped is destined to become a loop, Audio Loop Maker finds a seamless length for it.
