Audio Brewers Releases ab Compressor Limiter for Ambisonics

Audio Brewers has introduced ab Compressor | Limiter, a three-dimensional dynamics processor designed for Mono, Stereo, and Ambisonics signals. This plugin works internally in Ambisonics, making it compatible with any speaker array, from headphones and surround systems to Dolby Atmos. As a result, it offers a new approach to compression and limiting in immersive audio production.

Per-Pole Spatial Control

Traditional compressors process the entire mix equally. In contrast, ab Compressor | Limiter lets you shape compression, brickwall limiting, and harmonic saturation throughout the soundfield. Each dimensional pole – Front, Back, Left, Right, Top, and Bottom – can be processed independently. Moreover, you can link dimensions together for familiar bus workflows or decouple them to process each region separately. For instance, you can tighten transients at the front while preserving natural dynamics behind the listener.

Furthermore, the plugin offers independent control over Threshold, Ratio, Attack, Release, Make-Up Gain, Output, and Saturation. Therefore, every adjustment becomes a spatial decision, turning simple dynamics processing into a creative tool for sculpting sound in three dimensions.

Applications and Compatibility

Whether you are producing music, mixing for film, creating game audio, or building VR experiences, ab Compressor | Limiter supports true spatial dynamics processing. It is compatible with Windows, macOS (Intel and Silicon), and major DAWs that support multichannel tracks. Additionally, the plugin is available in AAX, VST3, and AU formats. Meanwhile, an iOS version called ab Compressor | Limiter X brings the technology to iPhone and iPad, both as a standalone app and an AUv3 plugin.

The iOS version works with GarageBand, Logic Pro for iPad, Cubasis, and AUM. However, it focuses on Stereo signals and provides independent control over Left, Right, and Front poles. It includes a compressor, brickwall limiter, and saturation stage, mirroring the desktop version’s essential controls.

Price and Availability

ab Compressor | Limiter is available at an intro price of 49,00 € (excl. VAT) until 15 October 2026. The regular price is 59,00 €. The iOS version, ab Compressor | Limiter X, costs 6,99 €. Consequently, the plugin offers a versatile solution for anyone working with spatial audio, though its unique per-pole processing is particularly valuable for immersive formats.
