Sampling+ works like CC-BY-NC but additionally forbids using the sound in commercial advertising
Sampling+ is the legacy fourth license still attached to some older Freesound sounds. Freesound’s interpretation: it grants roughly the same permissions as CC-BY-NC (attribution required, no earning money from the work) but adds one further restriction — the sound may not be used to make commercial advertisement. For example, you cannot build a track from Sampling+ samples to advertise a car. A downloader who encounters a Sampling+ badge must therefore apply the NC obligations plus the advertising ban, rather than treating it as an ordinary CC-BY-NC sound. This is the definitional content a user needs before deciding whether a legacy Sampling+ sound fits their intended use.
Examples
A Sampling+ ambient loop can appear in a non-commercial art installation with attribution, but may not be used as the backing track for a car commercial even if the ad-maker offers to credit the author.
Assessment
A designer wants to score a paid TV advert with a Sampling+ Freesound loop. Is this allowed under the license? Which single extra restriction distinguishes Sampling+ from CC-BY-NC?
