The bx_XL V3 is a mid/side mastering limiter plugin designed to deliver loud, polished masters with enhanced clarity. It builds on advanced mid/side technology, splitting the mid channel into two distinct bands—mid-low and mid-high—while also processing the side channel independently. This approach provides precise control over the stereo image and dynamics, allowing mastering engineers to sculpt the sound in detail and maintain clarity even at high loudness levels.

This plugin features a unique four-stage limiting process, including a dedicated limiter for the mid-low band that can isolate elements like the kick drum, enabling tailored limiting for increased punch and loudness without unwanted artifacts. After the multiband mid/side processing, the combined stereo signal is further refined with a true peak limiter, ensuring transparent loudness maximization. Additionally, the XL saturation controls introduce warm harmonic content that enriches mixes by adding subtle harmonics, enhancing perceived loudness while preserving sonic integrity.

Building on its predecessor's innovative phase-corrected mid/side auditioning capabilities, the bx_XL V3 introduces a three-band psychoacoustic loudness maximizer and comprehensive metering tools. These features provide detailed visual feedback including true peak, RMS, gain reduction, LUFS, and correlation meters, empowering users to achieve professional-level mastering results. The plugin also offers customization options such as a resizable interface and multiple color schemes, making it adaptable to various workflow preferences.
