BX3

BX3 Compressor is a three-band dynamic compressor built for mastering but flexible enough for mixing. It splits your audio into low, mid, and high bands, each with independent input/output level, threshold, attack, release, ratio, response, and knee width controls. A limiter module, RMS/peak detector switch, and lookahead delay up to 20ms give you precise control over transients and dynamics. Two selectable filter slopes and quick crossover knobs make it fast to dial in subtle gluing, tighten low end on drum-heavy tracks, or tame harsh highs. The frequency response plot and spectral analysis visualization help you see exactly what’s happening across the spectrum. BX3 is designed to sound organic and transparent, making it a solid choice for hobby producers and mastering engineers who want powerful multiband compression without a steep learning curve. It runs natively on Windows and Mac, so no extra hardware is needed.
