Surround Suite delivers all the control needed to define, enhance and fine-tune your surround mix to perfection. Achieve natural and coherent upmixing from stereo to 5.1 and 7.1 via Halo Upmix, take advantage of ISL's transparent True Peak limiting and SEQ-S's linear phase EQ in surround modes, and complement your surround workflow with Halo Downmix's precise and tweakable downmixing.

Natural extension
With unique centre channel management, including switchable dialog extraction, Halo Upmix is perfect for all types of production from archive restoration and TV through to the full 7.1 feature film experience. With surround delivery requirements becoming more and more common, a tool like Halo Upmix can be indispensable. Unlike legacy upmixing practices, Halo Upmix offers full downmix compatibility. For those working in Dolby Atmos, Auro 3D and Ambisonic environments, a 3D immersive audio option is also available.

Complement your workflow
Precise surround control, versatile downmix balancing and mix monitoring for accelerating and enhancing your surround productivity. Halo Downmix is the glue that brings your workflow together, allowing you to deliver in surround and stereo with ease and without compromise.

Transparent, reliable
No need to second guess your sample-peak limiter time and again, or deliberately increase headroom to avoid a downstream problem. Just dial in your True Peak limit and let ISL take care of the rest. Unlike traditional limiters, ISL provides a TPlim control, automatically adjusting transfer curve parameters for minimally invasive brick-wall protection.

Unparalleled flexibility
SEQ-S gives you EQ matching up to 7.1, with stereo mid/side operation and automated spectrum analysis. Automated EQ morphing allows for controlled scene transitions and creative sound design possibilities.

For post and broadcast
Surround delivery requirements are becoming more common, making a consistent surround workflow indispensable for anyone in post production. Expand your existing stereo and 5.1 mixes with zero artificial reverberation or chorusing effects, tweak and refine with True Peak limiting and powerful EQ sculpting/matching/morphing, and then fine-tune your downmix to ensure the best possible stereo fold-down.
