The RESONANCE Cycle™

 

“An infinite journey to higher fidelity—measured, modular, and musically transformative.”

The Discerning Listener Process

 
I. Overview

This end-to-end workflow unites eight RESONATE pillars, the LEDE evidence cycle, and five SPARC verification tools. It guides you from listener profiling through room and system calibration to final SPL validation. Every adjustment is backed by measurable inputs, actionable outputs, and clear checkpoints.

 

II. Core Frameworks

 
1. RESONATE

An eight-pillar roadmap organizing each phase of your audio-system journey:

  1. Recognize Your Listener Persona

  2. Evaluate Room Acoustics

  3. Synchronize System Components

  4. Optimize Psychoacoustic Alignment

  5. Navigate Treatment Prescription

  6. Assess Performance Improvements

  7. Tune Treatment Placement

  8. Enhance & Iterate

 
2. LEDE Cycle

A four-step, physics-driven loop applied at each RESONATE pillar:

  • Listen Intently

  • Evaluate Data

  • Diagnose Issues

  • Execute Remedies

 
3. SPARC

A final calibration suite—Speaker-Power & Acoustic-Response Calibration—using five tools to verify tonal, temporal, spatial and dynamic targets:

  • SOUND

  • PRAT

  • ATAC

  • RESOLVE

  • CLEAR

 

III. Step-by-Step Hierarchy

  1. Recognize Your Listener Persona

    • Apply PRAT’s Preliminary Profiling to map your listening type, SPL goals and room usage.

    • Document preferred genres, critical listening levels and upgrade path.

    • Checkpoint: Listener profile completed with clear targets for tonal neutrality and headroom.

  2. Evaluate Room Acoustics

    • Run LEDE: record baseline system behavior using pink-noise sweeps and music passages.

    • Use ATAC with room dimensions and surface data to generate reflection maps and treatment specs.

    • Use DFR Speaker-Location Calculator to define speaker-to-listener and speaker-to-wall distances.

    • Checkpoint: First-reflection points, modal peaks and early-reflection zones identified.

  3. Synchronize System Components

    • Execute SOUND analysis: measure component distortion, FR curves and dynamic range.

    • Optimize gain structure: align source output, electronics sensitivity and amplifier input levels.

    • Confirm crossover phase and driver summation.

    • Checkpoint: On-axis FR within ±1.5 dB of target curve; THD+N and dynamic range within spec.

  4. Optimize Psychoacoustic Alignment

    • LEDE listen session: perform critical listening sweeps, Haas effect and timbre balance tests.

    • Fine-tune toe-in, minimal EQ and time-alignment to preserve spatial cues.

    • Checkpoint: Perceptual coherence (depth, width, envelopment) matching reference recordings.

  5. Navigate Treatment Prescription

    • PRAT Reflectivity & Resonance Analysis: capture RT60 waterfall plots, identify modal builds.

    • Algorithmic Assessment: rank frequency bands by resonance severity.

    • Checkpoint: Treatment targets prioritized by their impact on clarity and decay times.

  6. Assess Performance Improvements

    • Re-run ATAC to capture updated RT60, C80/C50 and early-reflection reductions.

    • Execute CLEAR: calculate required amplifier wattage and speaker placement uniformity for target SPL.

    • Checkpoint: Measured RT60 within 10% of golden-ratio distribution; SPL target reachable with ≥3 dB headroom.

  7. Tune Treatment Placement

    • PRAT Treatment Placement & Tuning: install bass traps, first-reflection panels and diffusers as per ATAC map.

    • Measure incremental SPL and RT60 changes after each adjustment.

    • Checkpoint: Modal peaks suppressed by ≥6 dB; early-reflection echoes reduced to inaudible levels.

  8. Enhance & Iterate

    • Loop LEDE: listen to real-music passages, run RTA sweeps, diagnose any residual anomalies.

    • Execute minor tweaks: isolation feet, cable re-routing or digital jitter reduction.

    • Checkpoint: No new anomalies detected; system behavior remains stable across programs.

  9. Final Calibration & Verification (SPARC)

    • SOUND: reconfirm tonal signature and dynamic headroom.

    • PRAT: verify transient alignment and impulse-response coherence.

    • ATAC: validate treatment efficacy with updated RT60 and reflection measurements.

    • RESOLVE: apply final EQ/subwoofer calibration to tame any remaining modes.

    • CLEAR: confirm on-axis SPL delivery and amplifier headroom against your listening-level targets.

    • Checkpoint: All metrics within defined tolerances; system ready for consistent, predictable high-fidelity playback.

 

IV. Tool Matrix 

The Discerning Listener process is built on a rigorously structured sequence of phases—each governed by specialized frameworks and tools that transform subjective listening into a measurable, repeatable discipline.

 

We begin with Listener Profiling, using the PRAT-P module to define the listener’s persona, SPL targets, and room context. This foundational step ensures that system goals are clearly documented and aligned with musical intent.

​

Room Evaluation follows, powered by ATAC and the DFR Speaker Location Calculator. These tools generate reflection maps and identify optimal speaker positions, with verification based on precise spatial mapping and acoustic geometry.

​

In Component Synchronization, the SOUND framework assesses tonal balance, gain structure, and distortion metrics. Frequency response must fall within ±1.5 dB of the target curve, and THD+N must meet specification thresholds to ensure fidelity.

​

Psychoacoustic Optimization applies the LEDE cycle to refine spatial imaging and timbre balance. Depth, width, and envelopment are verified through critical listening and perceptual alignment.

​

During Treatment Prescription, PRAT-R and PRAT-A modules analyze modal behavior and rank resonance severity. Treatments are prioritized based on their impact on clarity, decay control, and spectral uniformity.

 

Performance Assessment revisits ATAC and CLEAR to validate RT60 decay metrics and amplifier headroom. RT60 must fall within ±10% of target values, and SPL must be achieved with ≥3 dB of dynamic margin.

 

Treatment Tuning is executed via PRAT-T, where acoustic panels, traps, and diffusers are installed and measured incrementally. Verification is confirmed when modal peaks are suppressed by ≥6 dB and early reflections are effectively damped.

​

In the Iterative Refinement phase, LEDE is re-engaged to identify and resolve any residual anomalies. The system must demonstrate stability across musical programs with no new issues detected.

 

Finally, Calibration & Verification is completed using the full suite of SPARC tools—SOUND, PRAT, ATAC, RESOLVE, and CLEAR. This comprehensive pass ensures that all tonal, temporal, spatial, and dynamic metrics fall within defined tolerances, confirming the system’s readiness for consistent, high-fidelity playback.
