Phaselith

Better audio through your existing headphones — restore lost detail from YouTube, Spotify, and any browser audio.

Notes: For the best listening experience, please reopen Phaselith for each new page before listening. Also, switch your device to High Performance power mode. Make compressed YouTube / Spotify audio feel clearer, less flat, and more open — directly in your browser. Phaselith is a real-time audio restoration engine that runs directly in your browser. It analyzes playback in real time and recovers lost harmonics, air, and detail that compression destroys — making voices clearer, instruments more vivid, and the soundstage wider and more natural. This is not an EQ or bass booster. Phaselith uses a 6-stage signal analysis pipeline with self-validation: it detects what compression damaged, generates candidate repairs, and only applies changes that pass a mathematical consistency check. If a repair doesn't improve the signal, it's rejected automatically. ### How It Works 1. **Damage Detection** — Identifies codec cutoff frequency, clipping artifacts, dynamic compression, and stereo collapse. 2. **Signal Decomposition** — Separates audio into harmonic, air, transient, and spatial components. 3. **Residual Synthesis** — Generates candidate repairs using physical models (not neural networks). 4. **Self-Validation** — Repairs are checked against a consistency model. Failed repairs are reduced or rejected before mixing. 5. **Perceptual Mixing** — Validated repairs are mixed at safe levels with loudness compensation and peak protection. 6. **Ambience Preservation** — Reverb tails and spatial cues are preserved, not destroyed. ### Who Is This For - 🎵 Music listeners who want richer sound from YouTube, Spotify, and browser playback - 🎙️ Podcast listeners who want clearer, more natural voices - 🎧 Headphone users who want better audio without buying new hardware - 💻 Anyone who notices browser audio sounds flat compared to dedicated players ### What Makes Phaselith Different Most audio enhancers add bass boost, virtual surround, or EQ curves on top of your audio. Phaselith analyzes degradation patterns and applies bounded, validated repairs — not a fixed tonal recipe.
