Virtual Tempest Engine

Cloud processing for System T

256 processing paths in the cloud

Leveraging patented x86 CPU optimal core processing (OCP) technology, SSL has virtualised the System T Tempest DSP Engine. The cloud-based Virtual Tempest Engine (VTE) operates within a virtualised Linux environment optimised for low latency throughput, providing real-time, deterministic audio processing and mixing. System T Cloud offers truly flexible capabilities with virtualised processing, control, and audio routing. It provides up to 256 processing paths, including support for stereo, 5.1 and immersive formats, all controlled via hardware or software interfaces from any location. These interfaces are specifically designed for broadcast production and provide a familiar feature set for broadcast audio mixers. VTE provides filters, EQ, dynamics processing, automixing and delays on all channels and buses, plus an inbuilt effect rack. Mix minus, monitoring and talkback features are included in addition to main program buses, stem groups, track buses and auxiliary outputs. Any channel or bus can be mono, stereo, 5.1, 5.1.4 or 7.1.4, providing a full toolkit for immersive productions and Dolby Atmos workflows.

VTE key features: 

  • Virtual Tempest DSP Engine for Linux and public cloud (e.g. AWS).
  • Scalable DSP featuring flexible and agile processing capacity.
  • Up to 256 processing paths across a pool of DSP.
  • Path processing features - 256 Dyn, 256 EQ, 128 Delay.
  • Built-in Effects Rack and Automixers.
  • Full immersive formats up to 7.1.4 with 9.1.6 monitoring.
  • Dante Connect cloud audio transport and routing.
  • 256x256 Dante Connect connectivity on Virtual Tempest Engine.
  • NDI conversion options.
  • Cloud AoIP routing for unlimited total I/O capacity.
  • SSL's patented Optimal Core Processing Technology.

System T Cloud - the future of broadcast audio 

Deploying VTE

A software subscription provides 256 paths of cloud audio processing. VTE is deployed alongside a cloud instance of TCA, for software control. These instances are fully remotely controllable from any of the System T control surfaces, or TCA and fader tiles on the ground in a control position. VTE utilises Audinate’s Dante Connect within the virtual DSP, to provide direct integration and routing of 256 inputs and 256 outputs within System T Cloud. Dante audio routing control is managed directly from the UI, then stored and recalled with the showfile. Users gain the ability to quickly define, configure and deploy cloud-based Dante audio solutions with System T Cloud. Dante Connect provides synchronous audio transport and full channel-by-channel audio routing between System T Cloud and any other Dante Connect instance or on-prem Dante hardware.
