Pro Extensive asset information
Each sample has a details page which includes a waveform view, a full-length audio preview, user-assigned tags, author-assigned "pack" grouping, and an author chain ("remixes and sources") for derivative assets.
Pro Creative Commons licensing
All assets made available through Freesound are required to be licensed under either CC0, CC-BY or CC-BY-NC.
Con Some assets may have restrictive licenses
Freesound permits uploaders to select the CC-BY license, which disallows the use of DRM, and the CC-BY-NC license, which disallows commercial use entirely. Licenses are prominently displayed on an asset's details page, and represented by a small icon in list views, but there is no option to filter by asset when searching or browsing.
Con Audio samples and sound effects only
Freesound does not host music tracks, or any kind of non-audio asset.
