Lawo has introduced the Home mc² DSP app, the microservice-based equivalent of Lawo’s A__UHD Core.

A new member of the Home Apps family, the ultra-low-latency Home mc² DSP app is a server-based, agile audio engine, combining the flexibility of the Home Apps platform in terms of connectivity and scalability with Lawo’s audio processing. The app can be used together with mc² mixing consoles or to instantiate a (virtual) mixing system wherever audio processing is required at short notice.

Lawo Home mc² DSP appWith features known from the A__UHD Core FPGA processing platform in a CPU-based package, Home mc² DSP allows operators to spin up mc²-grade DSP processing with ‘hitherto unthinkable granularity’.

Home mc² DSP’s primary purpose is to provide audio processing in situations where no A__UHD Core is available or where remaining within the Home Apps realm is more practical. As a member of the Home Apps platform, the Home mc² DSP app benefits from the agility afforded by the abstraction of processing functionality from the hardware: it leverages Lawo’s Flex licencing and subscription model, allowing users to reallocate subscription credits to any available Home App, whether audio or video, for tight budget control. It is also easy to ‘move’ from one location – a production hub, say – to another, such as an OB truck or a remote location.

Despite its CPU-based technology, the Home mc² DSP app performs at the same ultra-low latency as its hardware companion. All capabilities and characteristics are so similar that operators are unable tell whether their console surface or headless mixer controls a hardware-based A__UHD Core or the mc² DSP app. Switching between the two and back is possible at the push of a button in the Home UI.

The Home mc² DSP app automatically scales with future CPU developments and can provide several thousand DSP channels where needed. With support for mono, stereo, 5.1, and NGA Immersive Mixing formats; a flexible number of AUX, GRP and Sum buses, Home mc² DSP is the app-based alter-ego of the A__UHD Core. Any Home App can be stopped at any time, freeing up server capacity, Flex Subscription credits, and reducing power consumption in the process.

‘Home mc² DSP leverages the unique granularity and flexibility of the Home Apps platform regarding input and output media transport protocols,’ says Christian Struck, Lawo Senior Product Manager, Audio Infrastructure. ‘It will support mixed-format SMPTE ST2110, NDI, and SRT production environments, and newer formats that may become relevant further down the line. There are no plans to discontinue the A__UHD Core as it remains the processing tool of choice for audio-only workflows in a live-sound context.’

‘The introduction of the Home mc² DSP app is the next milestone in Lawo’s audio history,’ says Lucas Zwicker, Senior Director, Workflow and Integration, CTO Office. ‘This is not a lift-and-shift implementation of an existing product: Home mc² DSP has been carefully reengineered from scratch to cope with tomorrow’s requirements regarding converged audio, video and commodity-based processing infrastructures. Of course, we deliver the sonic performance our customers have come to expect from mc² mixers.’
