🎛️ Audio Processing Engine

The enhancer uses a structured signal chain:

1. Low Shelf Boost (~95Hz) – Adds deep bass foundation

2. Impact Peak (~60Hz) – Improves punch perception

3. Midrange Cut (~350Hz) – Reduces muddy resonance

4. Presence Enhancement (~3kHz) – Improves clarity and speech definition

5. High Shelf Control (~9kHz) – Smooths harshness

6. Dynamics Compressor – Balances loudness peaks

7. True Peak Limiter – Protects against distortion

All processing is executed locally inside the browser.
