Blue Cat's Protector is a stereo brickwall limiter plugin designed to offer precise control over your audio dynamics. It features a 0 dB brickwall peak limiter and waveshaper that allow users to smoothly transition from transparent limiting to more aggressive digital clipping or soft analogue saturation. This flexibility makes it suitable for a wide range of applications, from mastering to loudness maximization and creative distortion effects.

Despite its simple interface with minimal controls, the plugin delivers a broad sonic palette, enabling detailed shaping of the dynamics response. It includes stereo link control for balanced processing, a DC filter to eliminate unwanted DC offset, and comprehensive metering with zoomable peak, RMS audio levels, and gain reduction indicators. These features support accurate monitoring and fine-tuning of your sound with ease.

Blue Cat's Protector also offers advanced functionality such as sidechaining, allowing for unique compression techniques and creative dynamic shaping without introducing latency. Its fully configurable dynamics response histogram provides visual feedback to help optimize your settings. Overall, this plugin is a powerful tool for achieving controlled loudness and dynamic impact across various mixing and mastering scenarios.
