Three Mastering Modes, One App

Pick the mode that fits the track. All three run on-device. No cloud, no upload, no waiting.

V1 FAST

Quick & Direct

The fastest path from drop to mastered. Ideal when you trust the source mix and want a clean, pro-level result with no extra steps.

V3-QA

Analyzer-Driven

The Quality Analyzer reads the source first and builds a per-track plan. Mastering is then tuned to that specific song, not to a fixed preset.

V4-AI

Sorinel-Assisted

Our proprietary Sorinel AI runs on the Apple Neural Engine to prepare the source before mastering. The deepest, most detailed result.

Sorinel and the mastering engine are proprietary technologies developed by Software Evolution. All processing runs locally — no audio ever leaves your Mac.

LR4 SO/40: The Heart of Instant Mastering

LR4 SO/40 is the limiter that lies at the foundation of Instant Mastering. It wasn't created out of commercial necessity, but from curiosity and play: the desire to understand and recreate a modern, intelligent limiter capable of bringing a track to a professional level without destroying its identity.

The idea started from modern limiters, like those in Ozone, which "think" before applying limiting. We wanted something similar: a limiter that analyzes music before intervening, not one that brutally cuts peaks. 🧠

LR4 SO/40 works on four zones of sound — lows, bass, mids, and highs — treating each part exactly as much as needed. Tracks that already sound good are left untouched. Those that need help are corrected discretely, until they reach a pleasant and powerful balance.

The goal is not to destroy the dynamics or character of a track, but to make all music sound like it's from the same movie: the same volume level, the same impact, and the same clarity, regardless of source.

The process is more careful and more intense than in a regular limiter. That's why LR4 SO/40 masters one track at a time. It's a conscious choice: more analysis time means a better result. ⚡

LR4 SO/40 is not an aggressive limiter. It's a limiter that listens to music.

This is the story of Instant Mastering. ✨
