Browser sampler

A sampler that lives in your browser: load a sound, chop it, play the pads, and sequence the beat.

Chppr is built for the moment when you have an audio idea and want to try it immediately. No DAW session, no plugin folder, no setup ritual. Open the browser, drop audio, and start shaping it into something playable.

Chppr sequencer view for programming chopped samples — The sequencer turns played chops into repeatable patterns.

What you get in the browser

A waveform editor for selecting the part of the source you want.
Automatic and manual chopping modes.
Pad playback for slices, including pitch and reverse tools.
A 4-track step sequencer for building patterns.
BeatArc arrangement for turning loops into a longer structure.
WAV export when the sketch is ready to leave the browser.

Why use a browser sampler

No install before the first idea. Open the page, add audio, and test a chop without managing plugins.
Sampler and sequencer together. Turn sounds into pads, then program the groove in the same workspace.
Useful for quick decisions. Find out whether a loop has musical potential before starting a full session.
Export when it is worth keeping. Take WAV audio out when the sketch is ready to continue elsewhere.

When a browser sampler is useful

Browser tools are best when the cost of opening a full production environment feels too high. Chppr is good for testing a loop, preparing chops before a DAW session, sketching on a laptop or tablet, or sharing an idea quickly.

It is not trying to replace a full DAW. It is the fast sampler stage before the full session: find the idea, make it move, then export or keep building.

From sound to beat

Load or record audio

Upload a file, record from the microphone, or use the built-in sample beat to test the sampler immediately.

Turn the audio into pads

Slice a selected region and play each piece like a compact instrument.

Sequence the groove

Program hits across tracks, change BPM and swing, then arrange the result with BeatArc.

If you want a slicing-specific explanation, use the sample slicer page. If you want a full walkthrough, start with the tutorial.

Common questions

Is Chppr a sampler or a sequencer?

Chppr is both: a browser sampler for chopping and playing audio, plus a step sequencer for turning those chops into patterns.

Does it work without downloading software?

Yes. Chppr runs in modern browsers and does not require a desktop install to start chopping and sequencing.

Can I use my own samples?

Yes. You can upload audio files, record from the microphone, or use a built-in sample beat to test the sampler.

Can I export audio from the browser sampler?

Yes. Chppr can export WAV audio after you chop, sequence, or arrange an idea.
