Four promises.

Our job is not adding tools. It is removing doubt.

We build what's missing - あったらいいなを形に

Every plugin begins as a wish in a real session: a tool we wanted and could not find. So we build the missing piece, then give it away.

Old soul, new engine - ヴィンテージと最新テクノロジーの融合

We keep what the classics got right and rebuild it with today's technology. The warmth and musicality of legendary gear, running on a fast, precise, modern engine.

From the studio to the bedroom - スタジオからベッドルームへ

These tools are built by someone who mixes every day. Only real studio problems become products, one at a time.

Free for everyone - 全ての人に、無料で

Every Okina Audio plugin is free. Professional tools should not stand between you and the music you want to make.
