Spectral Lab

A listening index for analysis, perception, and resonance

A connected research environment for spectral analysis, psychoacoustic listening, and instrument-focused sound experiments. Each lab runs as an independent tool, gathered here under one navigable research surface.

Modules

Each tool is available from a stable path on the site.

01
LAB-01

Spectral Analysis Workstation

A research tool for uploading short audio excerpts and analyzing spectrograms, partial structures, harmonicity, roughness, and psychoacoustic metrics.

02
LAB-02

Spectral Psychoacoustic Lab

A browser-based listening laboratory for exploring beating, roughness, fusion, harmonicity, brightness, noise, and spectral perception.

03
LAB-03

Harmonic & Subharmonic Explorer

A composition-focused workbench for exact harmonic and subharmonic ratios, microtonal pitch approximation, playback, notation, and String Lab transfer.

04
LAB-04

Spectral Strings Lab

A minimal browser-based spectral string instrument for harmonic exploration, resonance, and interactive sound performance.
