## Description

This project is a system audio processor and digital signal processing engine designed to enhance system-wide sound volume and clarity. It functions as a high-fidelity sound enhancer and parametric audio equalizer that shapes the sonic profile and timbre of audio across all output devices.

The software utilizes a virtual audio device driver to intercept system audio streams at the kernel level, redirecting them through a processing pipeline. This allows for real-time sound processing and low-latency audio filtration to minimize the delay between sound generation and output.

The system covers capabilities for multi-band parametric equalization and audio enhancement, enabling the adjustment of specific frequency bands to customize the output for different speakers or headphones.
