RJ Labs conducts small‑scale audio experiments oriented toward heavier sound design. all units are developed during off‑hours, tested under irregular conditions, and released when results remain stable. the lab follows no fixed schedule or commercial agenda; research continues only as long as the behavior remains interesting.
