Effect Cells - 05_10_02

Status: ✅ COMPLETED Date: 2025-10-14 Version: 1.0.0

Overview

This module contains 3 professional effect cells implementing high-quality audio processing:

  1. ReverbCell - Freeverb-based algorithmic reverb with early reflections
  2. MultiBandDynamicsCell - 4-band multiband compressor/expander/limiter/gate
  3. DelayNetworkCell - Complex delay network with feedback matrices

All cells inherit from CellBase and implement the ICellL2 interface.

Presets: Small Room, Large Hall, Plate Reverb, Vocal Reverb, Cathedral, Drum Room, Shimmer Pad, Frozen Space, Spring Reverb, Dark Chamber

MultiBandDynamicsCell

Algorithm: Linkwitz-Riley crossovers + per-band dynamics

Features: - 4 frequency bands - Per-band: Comp/Exp/Limit/Gate - Threshold, Ratio, Attack, Release, Gain, Knee - Solo/Mute/Bypass per band - RMS/Peak detection - Auto-makeup gain

Presets: Mastering Glue, De-Esser, Bass Enhancer, Broadcast Limiter, Vocal Presence, Drum Bus Comp, Noise Gate, Upward Expander, Gentle Master, Aggressive Pump

DelayNetworkCell

Algorithm: 4 delay lines + Feedback matrix

Features: - 4 independent delays (1-2000ms) - Per-line: Time, Level, Pan, Filter - Feedback matrices: Identity, Hadamard, Householder - Modulation (chorus/flanger) - Ducking/sidechain - Ping-pong stereo

Presets: Ping Pong Delay, Dub Echo, Shimmer Delay, Dotted Eighth, Slap Delay, Ambient Wash, Tape Echo, Reverse Delay, Quarter Note Delay, Infinite Space
