SFX Lab · Skill + studio · Packaged

SFX Lab is a Claude Code skill that makes sound effects and learns what you like. An agent proposes the batch and shows the price, a generator makes the audio, you rate each sound in a local studio, and the agent rewrites a short taste file for the next batch.

SFX Lab · 01 / 06

Ask in plain words.

Say what you want, the way you would tell a person.

A request for six soft whooshes for a title card is typed. A plan card shows six sounds and says the price is shown first, and Approve is pressed. Six sounds land one after another on a map where brightness runs left to right and length runs bottom to top. Each gets one to five stars: the liked ones grow and turn bright, the others shrink and dim. A ring draws itself around the liked ones and is labelled your taste. The next six sounds land, and five of them land inside the ring.

Why it exists

Finding one sound means scrolling a library of thousands. A generator can make any sound, but it has no idea which ones you like.

  • Without it: Scrolling libraries for one whooshWith it: You ask in plain words
  • Without it: Every request starts from zeroWith it: Each batch starts from your taste
  • Without it: Money spent before you know the costWith it: The price is shown first

What it does

  • You ask in plain words. Claude plans the batch and asks before spending

  • SFX Studio is a local browser app to listen, compare and rate

  • A taste file grows with every rating, and the next batch follows it

  • It offers the sounds you already rated well before it makes new ones

  • Each show or client keeps its own taste as a separate project

  • It can sound-design a whole edit: one cue per cut, with files for Final Cut Pro and DaVinci Resolve
