Calrec ImPulseV DSP software adds AMPP integration and flexible licensing

The shift toward software-defined audio processing allows broadcasters to move away from proprietary hardware in favor of standardized COTS servers and cloud infrastructure. By integrating with the EBU’s Dynamic Media Facility project, Calrec is positioning its audio engine as a modular component within a shared vendor-agnostic stack. This interoperability, specifically the bidirectional control with Grass Valley’s AMPP, reduces the technical friction of managing complex live production environments. For the broader ecosystem, this signals a move toward containerized functions that share memory and compute resources to maximize hardware utilization. Watch for the performance benchmarks of ImPulseV on standard server hardware to determine if specialized DSP hardware is becoming obsolete for high-tier live events.

The EBU's Dynamic Media Facility initiative has been steadily building momentum as a framework for software-defined, vendor-agnostic broadcast production. In early 2026, the EBU published updated specifications for its Dynamic Media Facility architecture, outlining containerized media functions that share compute resources across COTS hardware, providing a common reference model that vendors like Calrec, Grass Valley, and Lawo can target for interoperability. The project's goal is to replace monolithic, proprietary broadcast chains with modular software functions that can be orchestrated dynamically based on production needs. Calrec's ImPulseV integration represents one of the first audio-specific implementations aligned with this vision, joining video and networking functions already demonstrated by other participants.

Grass Valley's AMPP platform has emerged as a key orchestration layer for this new class of software-defined facilities. Grass Valley expanded AMPP's partner ecosystem at IBC 2025, adding more than 30 third-party integrations across audio, video, and control-plane functions, signaling that the platform is moving beyond its initial video-processing focus into a broader production infrastructure role. NEP Group, one of the world's largest outside broadcast providers, has been an early adopter of AMPP-based workflows for live sports and entertainment events, testing containerized audio and video functions in production environments. The subscription licensing model Calrec is introducing with ImPulseV aligns with AMPP's own consumption-based pricing, making it easier for production companies to scale audio processing up or down per event without capital expenditure on dedicated hardware.

On the technical side, the shift toward COTS-based audio DSP is being validated by independent testing and real-world deployments. Calrec demonstrated ImPulseV running on standard x86 server hardware at the 2025 NAB Show, processing 128 channels of audio with latency under 5 milliseconds, a result that challenges the assumption that high-channel-count live mixing requires proprietary DSP silicon. Henry Goodman, Calrec's head of product, has emphasized that the Terraform-based deployment automation allows broadcasters to spin up and tear down audio processing instances in minutes, matching the elastic resource model that cloud-native video platforms already use. The combination of smaller DSP pack sizes and automated provisioning positions ImPulseV as a building block for the EBU's vision of facilities where media functions are allocated on demand rather than permanently installed.
