ONRI Audio REISEI 1.0.4
REISEI is a one-screen mastering processor from ONRI Audio that keeps spectrum analysis, EQ, dynamics, saturation, stereo imaging, and limiting all visible in a single view. Its standout PARTIAL EQ mode uses additive resynthesis to lock onto and follow individual harmonics, while ITU-R BS.1770-4 metering and a mode-based limiter round out a complete, workflow-focused mastering chain.

About ONRI Audio REISEI 1.0.4 for Mac
REISEI is a one-screen mastering processor developed by ONRI Audio, built by a designer and mastering engineer based in Japan who originally created it for his own sessions. The plugin's name, REISEI (冷静, pronounced "ray-say"), translates to "a calm, steady mind" — a concept that directly shapes the tool's design philosophy: rather than assembling a rack of separate plugins and hopping between windows, REISEI keeps spectrum analysis, EQ, dynamics, saturation, stereo imaging, and limiting all visible and adjustable from a single view. What distinguishes REISEI most is its PARTIAL EQ mode, built on additive resynthesis. Instead of applying a filter across a fixed frequency band the way conventional EQ does, PARTIAL locks onto individual harmonics actually present in the source material and follows them as pitch moves — a fundamentally different approach to tonal shaping. This sits alongside a conventional EQ section with five EQ models, two independent DE-DYN dynamic band processors for tasks like de-essing or resonance control, and a stereo-imaging approach that stays in L/R throughout rather than switching to mid/side, using a per-band WEIGHT control to blend mid or side elements in by degree instead.
