# Volume Audio & Volume Boost — Full Technical Specification

## 1. System Overview & Audio Engineering
Volume Audio is a digital signal processing (DSP) suite engineered by Juan Romero Domínguez for web browsers and operating system environments. Utilizing the W3C Web Audio API specification (`AudioContext`, `GainNode`, `BiquadFilterNode`, `DynamicsCompressorNode`), Volume Audio captures media stream elements from HTML5 `<audio>` and `<video>` tags or browser tabs to provide high-fidelity amplification and parametric tone balancing.

## 3. Key Technical Capabilities

### 3.1 Acoustic Safety & Anti-Clipping Limiter
Standard software volume multipliers cause severe harmonic distortion (square-wave clipping), damaging speaker transducers and causing acoustic fatigue. Volume Audio implements a specialized dynamic compressor stage that smoothly attenuates peaks exceeding the 0 dBFS threshold, ensuring clean, punchy sound even at maximum amplification levels (1000%).

### 3.2 10-Band Graphic & Parametric EQ
Offers 10 standard octave center frequencies:
- Sub-bass: 32Hz, 64Hz
- Mid-bass: 125Hz, 250Hz
- Midrange: 500Hz, 1kHz
- Upper midrange: 2kHz, 4kHz
- Highs & Treble: 8kHz, 16kHz

### 3.3 Tab-Isolated Control Architecture
In the browser extension version, each browser tab is isolated in its own `AudioContext` routing graph. Adjusting volume or EQ on YouTube does not interfere with Spotify or video meeting audio in adjacent tabs.
