Earshot gives coding agents ears to judge and make sound effects

Opus 5.5 could already build launch videos in code, but its sound effects were sloppy. Earshot lets agents listen to sounds, rate them and create better ones; every sound in the demo video was made with code.

Introducing earshot

Opus 5.5 can build a whole launch video in code but still produces sloppy sfx.

so we built earshot. it's ears for AI coding agents. they can now hear sounds, judge them and even make their own good sounds.

every sound in this video was made with code.
(sound on!!)
