DIFF Devices - PRECISE V2

DIFF Devices — PRECISE V2

PRECISE evolves from a mastering-focused precision EQ into a fully dynamic, surgical tone-shaping system. Built for engineers who demand absolute control, PRECISE now integrates advanced per-band dynamic processing while maintaining the clarity, phase integrity, and workflow philosophy that defined its original release.

At its core, PRECISE is entirely written in gen~ — not partially, not hybrid — but fully custom DSP from filter topology to dynamic engine. This ensures deterministic behavior, zero-latency response (in standard mode), and extremely stable real-time performance even under heavy automation.

Originally designed as a mastering-grade equalizer with brickwall filtering, PRECISE now expands into a professional Dynamic EQ platform while preserving its clean, controlled sonic identity.

Where Version 1.0 focused on static tonal excellence, Version 2 introduces intelligent movement — allowing frequencies to respond only when necessary. The result is a processor that can be transparent and invisible, or surgical and corrective, without ever compromising tonal balance.

WHAT’S NEW IN VERSION 2.0

• Full Dynamic EQ engine

• Per-band Threshold, Range, Attack & Release

• Downward & Upward dynamic modes

• Mid/Side processing architecture

• Dual-Mono support

• 12–96 dB/oct LC/HC slope control

• Click-free slope transitions

• Advanced band-contribution detection

• Side-channel detector boost (M/S mode)

• Per-band dynamic metering architecture

• Improved smoothing and clickless parameter transitions

• Real-time spectrum enhancements

CORE ARCHITECTURE

• 100% gen~ DSP Engine

PRECISE is completely written in gen~, including:

• Filter topology
• Dynamic envelope detection
• Slope morphing
• Mid/Side matrix
• Smoothing systems

This allows:

• Zero-latency operation (standard mode)
• Phase-coherent summing
• High stability under automation
• Efficient CPU usage

FEATURES (VERSION 2)

• 8-Band Precision EQ

LowCut, LowShelf, Bell 1–4, HighShelf, HighCut

Designed for mastering accuracy and mix-level flexibility.

• Dynamic Processing (LS + B1–B4 + HS)

Dynamic control is available where it matters most musically, intentionally excluding LC/HC for stability and clarity.

Each band includes:

• Threshold (dB)
• Range (dB)
• Attack (ms)
• Release (ms)
• Mode: Downward or Upward

• Downward & Upward Modes

• Downward reduces gain when threshold is exceeded.
• Upward expands or enhances frequencies only when they fall below threshold.

Perfect for:

• Controlling harsh resonances
• Dynamic presence boosts
• Low-end tightening
• Transparent vocal control
• Mastering tonal stabilization

• Band-Contribution Detection

Instead of relying on broadband detection, PRECISE measures each band’s energy contribution using a pre/post comparison model.

This keeps dynamic behavior focused, stable, and musically accurate.

• Stereo / Dual-Mono / Mid-Side Modes

Three processing architectures:

• Stereo Linked
• Dual-Mono (Left/Right independent)
• Mid/Side (A = Mid, B = Side)

The Mid/Side matrix is orthonormal and phase-safe, ensuring clean reconstruction.

• Side Detector Boost (M/S Mode)

Optional 0–24 dB boost for Side detection sensitivity without altering actual Side gain.

• Advanced LC/HC Slope Control

8 selectable slopes:

12 / 24 / 36 / 48 / 60 / 72 / 84 / 96 dB per octave

Slope changes use a click-free internal crossfade system for smooth transitions.

• Controlled Resonance Behavior

LowCut and HighCut Q range: 0.1 – 30

Resonance handling is optimized to avoid unexpected volume jumps when increasing slope or Q.

• Spectrum Analyzer

High-resolution real-time spectrum display with band visualization and clear frequency targeting.

• Clickless Smoothing Architecture

All continuous parameters and routing states are smoothed to eliminate:

• Zipper noise
• Pops
• Switching artifacts
• Automation glitches

SOUND PHILOSOPHY

PRECISE is designed to remain:

• Transparent when subtle
• Surgical when needed
• Stable under mastering conditions
• Reliable in complex automation scenarios

Unlike many dynamic EQs that rely on generic compression structures, PRECISE’s dynamic behavior is deeply integrated into the EQ architecture itself — resulting in smoother, more predictable tone shaping.
