Uncommon Ear

Uncommon Ear is a searchable catalog of free music and sound effects released under Creative Commons licenses, most of them CC0. The connector lets Claude search the catalog by keywords, mood, genre, instrument, length, tempo and license terms, look up a single track, and find similar tracks. Every result names its license, says whether commercial use is allowed and whether credit is required, and includes a ready-to-paste credit line, a preview link and, where available, the original file.

Search works without an account. By default results are curated: an editor-screened set with one result per numbered family of near-identical files, so a search for footsteps returns distinct sounds rather than twelve takes of the same one.

With a free account, Claude can also save tracks to collections and sound boards, reorder and annotate them, export one credits file for a whole collection in text, Markdown, CSV or JSON, and render a short edited WAV of a track (trim, fades, loop, reverse, speed, gain, loudness) with the credits embedded. The first time one of these tools is used, Claude asks you to connect your account.
