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. The result: your music sounds closer to how it was meant to be heard.
