Sampling Copyright and Clearance
Sampling needs two clearances, composition and recording; a file licence is not a work licence.

The problem
Why can a two-second drum loop not simply be dropped into a track?
How it works
A recording usually carries two layers of rights. One is the composition, owned by the writer; the other is the recording, owned by the person or company that captured the sound. Sampling uses both, so both need clearance. A public-domain work can still have a protected recording; conversely, an open file may encode a work still in copyright. The licence sets what is allowed: credit, share-alike and non-commercial terms all shape release. Fair use is a defence in some jurisdictions, not a default permission.
Practice and settings
Identify the source and the licence text, and keep a copy with the download date. Separate composition from recording and approach each rights holder. Where credit is required, put it in metadata and release notes. Whether changes must be shared depends on the original licence. Before release, build a clearance list with material, source, licence, obligations and expiry. When in doubt, replace the sample; it is cheaper than repairing later.
What to listen for
Hear the sample in the finished track and judge if it is recognisable. Recognisable melodies and timbres are identified easily and challenged often. Hear the processed fragment and check whether it still traces back. Hear the arrangement layer and decide whether you borrowed a melody, a groove or a timbre.
Common misconceptions
That a free download is free to use commercially; that pitch shifting removes the need to clear; that short samples are always safe.
