Sample chopper online

Chop audio samples in your browser, play the slices on pads, and turn them into a beat without opening a DAW.

Chppr is a free online sample chopper for producers who want to move quickly from an audio file to playable chops. Drop a drum break, melody loop, vocal phrase, field recording, or any short idea, then slice it on a waveform and trigger each chop from an MPC-style pad layout.

It runs in the browser. There is no install, no plugin, and no signup required to start chopping. Your local chopping session stays on your device unless you choose to publish a share link.

How to chop a sample

Load an audio source

Open Chppr and drop an audio file onto the page. You can also record from your microphone or load a built-in sample beat if you just want to test the workflow.

Choose the part you want to chop

Set the region on the waveform and focus on the part that has the groove, phrase, or texture you want to play.

Slice the sample

Use auto-detect for quick transient-based chops, or add and move slice points manually when you want more control.

Play and sequence the chops

Each slice becomes a pad. Trigger chops by hand, then use the step sequencer to turn the idea into a beat.

Export or keep building

Export WAV, build an arrangement with BeatArc, or save a project once the idea starts to feel worth keeping.

Who it is for

Chppr is made for quick sample-based ideas: chopping a loop, finding playable pieces inside a phrase, sketching a rhythm from slices, or preparing material to bring into a DAW. It is closer to a browser-based chop sampler than a full studio timeline.
