Opus

Opus Audio

Lolly makes this format

The modern, efficient audio codec built for the web: it sounds better than MP3 at much smaller sizes and is royalty-free. Lolly exports Opus (in a WebM container) as the soundtrack from tools like the Audiogram and Sequence Studio, and reads Opus in too as part of the OGG/WebM audio it decodes. Its WebM container carries a Content Credential Lolly's own verifier reads (the standard doesn't map C2PA into Matroska yet, so c2patool can't).
