About

Castle 11 Labs is an audio company based in Los Angeles. We build tools for the people who make records and mix live shows.

Every plugin starts as something we needed in our own sessions and couldn't buy. We build the thing we want, put it to work on real records, and only ship it if it holds up under real deadlines and real signal.

We have dealt with enough iLoks and never‑ending subscriptions. We are not putting you through that. Buy it once and it is yours.
