I study how the temporal organization of sound determines whether music is simply heard… or physically felt.

Core Expertise

Groove & Temporal Coherence Optimization
Improving temporal coherence in audio signals and playback systems to enhance groove perception, transient clarity, and perceptual continuity.

Psychoacoustic Audio Diagnostics
Advanced perceptual evaluation of micro-temporal coherence, transient integrity, and rhythmic clarity in audio systems.

Temporal Coherence Analysis
Analysis of time-domain behaviour in audio signals and playback chains to identify transient smearing and micro-temporal dispersion.

Sound Field Coherence Mapping
Identification of interference zones, phase interactions, and coherent listening points in multi-PA systems and complex acoustic environments.

Rhythmic Perception & Groove Dynamics
Evaluation of how temporal coherence affects rhythmic perception and audience psychomotor response.

Auditory Fatigue Analysis
Identification of technical and psychoacoustic factors that contribute to listener fatigue in audio playback systems.

Specialist in psychoacoustic analysis and temporal coherence in sound reproduction.

My work focuses on identifying and optimizing the temporal factors that influence auditory perception, including transient behaviour, micro-dynamics, rhythmic clarity, and perceptual continuity.

Through a combined perceptual and technical approach, I analyse recordings, mixes, and playback systems to detect temporal dispersion, loss of coherence, and perceptually critical listening zones in complex acoustic environments (multi-PA systems, live sound environments, and digital playback chains).

This work also includes in-situ analysis of live sound systems to identify points where the acoustic field maintains sufficient temporal coherence for rhythmic structures to remain perceptually stable and physically engaging.

The goal is not simply to measure sound, but to understand how the temporal organisation of audio influences groove perception, rhythmic intelligibility, and the overall listening experience.

This approach can contribute to improving perceptual clarity, rhythmic engagement, and listener experience in both music production and live sound environments.

When temporal coherence is preserved, rhythm stops being merely audible — and becomes physically compelling.
