EchoPsychFX

Psychoacoustic Perception FX

EchoPsychFX is not a delay plugin — it’s a subtle psychoacoustic perception processor. Instead of transforming the sound itself, it gently manipulates how the listener thinks the sound is positioned, sized, coloured, or emotionally framed. It's built to enhance perceived intimacy, width, warmth, presence, or distance, without pushing the audio into obvious effect-territory.

Everything inside the plugin works like a set of coordinated illusions — stereo micro‑behaviours, tilt EQ, width balancing, spectral tilt, micro‑modulation, spatial cues, and perception‑based presets that reshape the listener’s experience while keeping the artist’s original tone intact.

Core Components

Width Balancer: Smooth, perceptual stereo rebalancing without collapsing mono integrity.
Tilt EQ: Psychoacoustic tonal shaping based on brightness–warmth perception curves.
Mod Delay (Micro Modulation): Subtle depth, movement, and stereo motion.
Spatial FX: Phase and micro‑timing cues to shift perceived proximity and space.
Perception Presets: Centralized presets that control the entire psychoacoustic chain at once.

🧠 Designed Around Human Hearing

EchoPsychFX uses perceptual rules rather than traditional DSP tricks: Haas‑zone cues, loudness asymmetry, spectral emphasis, warmth illusion curves, micro‑offsets, and proximity weighting. The goal isn’t to sound like an effect — it’s to shape what the brain believes it’s hearing.

What It’s Best At

Making vocals feel closer, warmer, or more intimate without adding reverb or delay
Giving guitars and synths a wider, deeper feel without phasing issues
Making elements pop forward or sink back in a mix using perceptual cues
Adding movement and life to static sounds without sounding "modulated"
Giving mixes subtle spatial dimension without obvious effects

Tech Overview

Engine: C++ / JUCE
Processing Precision: 64‑bit
Preset Core: Central PerceptionPresetManager controlling global psychoacoustic states
Parameters: Controlled via modular components using public setters
Planned Additions: Micro‑pitch detune, L/R phase shift, exciter/saturation, and a tiny psychoacoustic pre‑delay verb — focusing next on something more noticeable on instruments.

Development Notes

EchoPsychFX is built from the idea that sound doesn’t need to be changed dramatically to feel dramatically different. Every algorithm is tailored for the way the human brain reconstructs spatial and emotional cues — not for dramatic FX processing. This makes the plugin extremely subtle, musical, and mix‑friendly.
