Sample Chopper

Auto-slice a long recording into individual samples wherever the audio gets quiet — drum hits, vocal chops, field recordings.

Anything quieter than this is treated as a gap between samples.

Gaps shorter than this don't trigger a split. 0.1 s catches drum hits.

About this sample chopper

Drop in a long recording — a drum take, a vocal chop session, a field recording — and the tool automatically splits it into separate sample files at every quiet gap. Each non-silent chunk becomes its own downloadable file.

Different from /split-by-silence in that it's tuned for short transient sounds (drum hits, vocal stabs, sound effects) rather than full songs. Defaults to a higher threshold and a much shorter minimum gap.

How to chop samples online

    Drop in a recording

    Drum take, vocal chops, sound effects, field recordings — anything with discrete events separated by gaps.

  2. 02

    Tune the threshold

    How quiet a gap needs to be. -28 dB is a good default for studio recordings.

  3. 03

    Download each sample

    Each detected event becomes a numbered sample file.

Sample chopper FAQ

Sample chopper vs split-by-silence — what's the difference?

Same engine, different defaults. Split-by-silence assumes long-form audio (songs, podcasts) and uses a 2 s minimum gap. Sample chopper assumes short events and uses a 0.1 s minimum gap, much more aggressive.

What threshold should I pick?

-28 dB works for tight studio drum recordings. -20 dB for noisier room takes. -35 dB for clean isolated samples. Tune until you get the right number of slices.

Are the slices sample-accurate?

The tool detects start/end of each silent region and cuts at those boundaries. The cuts are sample-accurate.

Can I get a single ZIP of all samples?

Right now each sample is a separate download. ZIP is on the wishlist if there's demand.
