Give Claude Code Ears: Let It Hear and Score the Sound in Your Videos
A free, open-source tool that turns sound into words Claude can read, scores your whole video against pro launch films second by second, and makes its own sound effects in code. How to set it up and the catches
Claude can write the code that renders a video, a product demo or a game, but it has never been able to hear what it made. earshot gives it ears. It describes any sound in plain words, finds the best moment in a long recording, writes a second-by-second listening transcript of a whole film, and scores your video against a profile of seven professional launch films with fixes tied to timestamps. It runs on your own computer, on the CPU.
What it does
- describe: what a file sounds like in words ("a single mechanical keyboard key press"), plus loudness and brightness.
- match / rank / find: how well a sound fits a description, the best file for it, or the best moment in a long take.
- timeline and sheet: a listening transcript of a video and an annotated picture of it (frames, events, spectrogram).
- critique: a launch-video scorecard against 7 professional launch films, with timestamped fixes.
- sfx and kit: a bank of 201 sound effects stored as code that render in seconds, aimed at a moment in the picture.
- mcp: the same tools as an MCP server for Claude Code.
