Audio Library
Search free-to-use provider audio, import it into workspace media, and render it on BlitzReels timelines.
The audio library searches external provider catalogs, normalizes license metadata, and copies selected audio into your workspace media library. Imported audio can then be reused like any other workspace audio asset.
Current providers:
openversefreesound(FREESOUND_API_KEYrequired server-side)wikimediaremotion(32 bundled sound effects from@remotion/sfx)
The API default is cc0. Use license=no_attribution to include CC0, public-domain, and Remotion SFX results.
Use license=attribution only when your workflow can preserve attribution text.
