Audio Brewers has released a three-dimensional dynamics effect plugin that works natively across mono, stereo, and Ambisonics signals.
Compatible with surround, binaural, and Dolby Atmos speaker arrays through Ambisonics decoding, ab Compressor | Limiter processes each of 6 dimensional poles (Front, Back, Left, Right, Top, and Bottom), independently. Any combination of poles can be linked together for familiar bus-compression workflows or decoupled to shape different regions of the soundfield on their own.
Whether you’re producing music, mixing for film, creating game audio, or building immersive VR experiences, “ab Compressor | Limiter” delivers true spatial dynamics processing for Stereo, Ambisonics, and Dolby Atmos workflows. From transparent compression and peak protection to analogue-style saturation and creative sound design, it transforms dynamics processing into a powerful tool for sculpting sound in three dimensions.
ab Compressor | Limiter features
- Independent compressor, brickwall limiter, saturation, and parallel mix per dimensional pole, with peak/RMS detection and 0-10ms lookahead.
- Per-pole threshold, ratio, attack, release, knee, make-up gain, saturation, and mix controls.
- Real-time pre, post, gain reduction, and spherical harmonic distribution visualization.
- Mono, Stereo, and Ambisonics sidechain (host-dependent) for spatially selective compression.
- Per-pole solo, mute, and A/B comparison.
- Cross-OS, cross-DAW preset system for moving, copying, and sharing presets.
ab Compressor | Limiter is available to purchase for the intro price of €49 EUR until October 15th, 2026 (regular €59 EUR). It comes in VST3, AU and AAX plugin formats for Windows and macOS. A companion app, ab Compressor | Limiter X, brings a stereo-focused version with Left/Right/Front poles to iOS as a standalone app and AUv3 plugin. It is priced €6.99 EUR.
