Real landing-page assets are now wired directly from the repository so README and GitHub Pages show the same product visuals.




Built like a compact mastering console.
Every module supports the single purpose: better local tab audio, with a clean UI and Web Store-friendly privacy posture.
MasAri smart presets
Balanced presets for music, audiophile listening, open-air character, podcast, movies, and night listening.
Analog 4-band color
Adds low punch, warm body, pleasant presence, and silky high-frequency sparkle without harsh distortion.
Phase-aware width
Low and vocal ranges stay controlled while high-side particles get a tasteful stereo lift.
Fluid visual engine
Spectrum and meters use smoothing to feel responsive while keeping CPU and memory usage lightweight.
Output routing
System Default uses a direct route; optional device routing is unlocked only by explicit user action.
Chrome Store ready
Manifest V3, no host permissions, no content scripts, no remote executable code, and clear privacy documentation.
Professional public release posture
The repository includes source code, documentation, Web Store packaging scripts, GitHub Release automation, GitHub Pages deployment, privacy policy, support page, and wiki pages. Store submission remains manual by design.
