Audio Brewers Releases ab EQ

Audio Brewers says that their ab EQ is designed with a plug-and-play mentality. A spokesperson told us, "It simply works!" Here's the details in their own words...

ab EQ is not just another equaliser - it's a three-dimensional one. Natively compatible with Mono, Stereo, and Ambisonics signals, ab EQ works internally in Ambisonics, making it compatible with any speaker array imaginable, including Dolby Atmos.

At its core, ab EQ is a fully featured equaliser with 10 bands per dimensional pole: every band exists in space. Each EQ band can be controlled independently across all dimensional poles - Front, Back, Left, Right, Top, and Bottom - allowing you to sculpt frequency content exactly where it lives in the soundfield.

You can link bands across dimensions for cohesive, traditional EQ moves, or completely decouple them to treat each spatial pole independently. This lets you, for example, attenuate low frequencies behind the listener, boost presence only on the sides, or soften high frequencies above without affecting the rest of the mix.

Each band is fully flexible and can be configured as a pass, notch, bell, or shelf filter, and placed freely anywhere across the frequency spectrum. Familiar EQ workflows are preserved, but expanded into three dimensions, where frequency balance becomes a spatial decision rather than a purely tonal one.

ab EQ is built for musicians, mixing engineers, and sound designers who want deeper control over immersive audio. You can use it transparently for corrective EQ, or push it into experimental territory where space and timbre merge into a single creative tool.

In essence, ab EQ is about control, clarity, and flexibility. It makes equalisation three-dimensionally intuitive, whether you're working in Mono, Stereo, Surround, or fully immersive formats like Dolby Atmos.

Do you have a Mono or Stereo source? ab EQ automatically converts it to Ambisonics so you can manipulate it three-dimensionally without changing your workflow.

Do you work in Stereo? Even when your final output is Stereo, all processing in ab EQ happens in Ambisonics. This allows you to rotate, reshape, and rebalance your sound in space before it's rendered back to Stereo, opening the door to unique binaural and spatial results.

Do you work in Surround, Dolby Atmos, or a custom multispeaker array? Because ab EQ operates internally in up to 7th-Order Ambisonics*, you can shape the frequency balance of any two- or three-dimensional source with exceptional spatial precision.

ab EQ is compatible with Mono, Stereo, and Ambisonics sources (1OA through 7OA*) and will output Stereo and Ambisonics signals that can later be decoded to ANY speaker array. From Binaural, to Surround and even to Dolby Atmos arrays.

ab EQ comes with a practical Preset system where you create your presets ONCE, and they are Cross-DAW and Cross-OS compatible! Meaning you can move your presets from Mac to Windows (or vice versa) and even share them with other users!

ab EQ also comes with a 'smart troubleshooting' algorithm, which will check your signal chain and let you know if something is wrong with it.
