Sample slicer online

Slice audio into pads, reshape the rhythm, and export the pieces from your browser.

Chppr is an online sample slicer for producers who want a fast path from an audio file to playable slices. It is made for breaks, loops, vocals, one-shots, field recordings, and any source you want to cut into rhythmic pieces.

What makes it a sample slicer

A slicer is different from a basic audio trimmer. Instead of cutting one file into one export, Chppr lets you create many small slices and play them as an instrument. You can keep the original groove, rearrange the order, pitch a chop, reverse a slice, or program a new pattern.

Why it works for slicing

Slice modes

Basic workflow

01

Drop audio

Load an audio file directly into the browser. Chppr reads common formats like WAV, MP3, FLAC, OGG, M4A, and AAC.

02

Choose the section

Drag across the waveform to focus on the phrase you want to slice.

03

Create slices

Use automatic detection for speed, or add cue points by hand when the feel matters more than the grid.

04

Play or export

Trigger the slices on pads, build a sequence, export WAV, or keep arranging inside Chppr.

What audio formats can I slice?

Chppr works with common browser-supported audio formats such as WAV, MP3, FLAC, OGG, M4A, and AAC.

Can I export slices as WAV?

Yes. You can export WAV slices after cutting the sample, or keep building the pattern inside Chppr.
