## Description

<strong>AudioCmprssr: Real-Time Audio Compression for the Browser</strong>
AudioCmprssr is a high-performance browser extension designed to provide real-time audio compression and volume normalization for all web-based audio and video content. Whether you are watching movies with inconsistent volume levels, listening to podcasts in loud environments, or seeking a more balanced music experience, AudioCmprssr gives you studio-grade control over your browser's sound output.

<strong>Key Features</strong>
-   Works with live streaming real-time audio
-   Real-Time Compression: Automatically reduces the dynamic range of audio to ensure consistent volume levels across different websites and media types.
-   High-Performance Engine: The extension utilizes a dedicated AudioWorklet thread for low-latency, high-fidelity processing that won't slow down your browser.
-   Professional Controls: Fine-tune your sound with adjustable parameters: Threshold, Ratio, Attack, Release, Knee Width, and Makeup Gain.
-   Visual Feedback: Monitor your audio in real-time with an integrated waveform visualizer and a precise gain reduction meter.
-   Smart Presets: Quickly switch between Low, Medium, and High compression profiles, or save your own custom configurations for different listening scenarios.
-  Sidechain Filters: Advanced Low Pass, Band Pass, and High Pass filters allow you to target specific frequency ranges for more precise compression triggering.
-   Modern Interface: An intuitive UI featuring rotary knobs and support for Light, Dark, and System themes.

<strong>Why Use AudioCmprssr?</strong>
Many web videos and streams suffer from sudden jumps in loudness (e.g. when dialogue is too quiet and action scenes or music are too loud). AudioCmprssr solves this by "squeezing" the audio signal, bringing quiet parts up and loud parts down to a comfortable, consistent level. 
Unlike simple volume boosters that can cause clipping and distortion, AudioCmprssr uses a sophisticated soft-knee compression algorithm and DC offset removal to maintain professional audio quality even at aggressive settings.

<strong>Privacy and Security</strong>
Your privacy is a priority. AudioCmprssr processes all audio locally on your machine. No audio data is ever recorded, stored, or transmitted to external servers. This extension does not collect any personal information.

<strong>Technical Specifications</strong>
*   Threshold: -40 dB to 0 dB
*   Ratio: 1:1 to 20:1
*   Attack: 1ms to 100ms
*   Release: 10ms to 1000ms
*   Makeup Gain: 0 dB to 10 dB
*   Architecture: AudioWorklet API for thread-isolated processing
