What jusst.engineering does

jusst.engineering is a Hamburg-based engineering studio specializing in contemporary audio streaming, audio signal distribution, and voice interface solutions. Founded as a family business by Julian and Sebastian Scheel in 2005 and operating full-time since 2013, the firm was reorganized in mid-2017 under the jusst.engineering brand to focus on consulting and contractual development work for audio technology clients. The studio operates as an official design partner for both StreamUnlimited Engineering GmbH (StreamSDK) and XMOS Limited, building products around XMOS processors, Linux/Yocto embedded platforms, bare-metal microcontrollers, and cross-platform mobile applications.

Its core offerings span a product portfolio and a services portfolio. The product side includes VocalFusion voice interfaces (full-duplex, stereo-AEC, noise and dereverberation suppression for ASR and far-field communication), an A52 5.1 surround decoder on XMOS XS2, MFi interface integration for Apple-authorized companies, advanced USB Audio 2.0 solutions supporting up to 32 channels and 768 kHz PCM/DSD512, and DSP features (asynchronous resampling, digital crossover filter sets) integrable into USB Audio, AVB, or I2S projects. The services side covers StreamSDK and XMOS firmware development, Linux and bare-metal engineering, Flutter/iOS/Android mobile development, and electronics design including analog, mixed-signal, and PCB work, with integration support for Chromecast, AirPlay 2, Spotify Connect, Tidal, Qobuz, Roon, MQA, and Dirac Live.

The business model is professional services: quote-based consulting engagements ranging from small advisory budgets to full development packages, sold through enterprise field sales targeting established audio brands, emerging audio-technology start-ups, and well-known companies across various industries. With roughly five employees, no external funding, and operations centered in Hamburg serving European clients, jusst.engineering is a tightly focused boutique whose revenue depends on a narrow set of project-based engagements routed through its two core technology partners.

Direct peers

• DSP Concepts: Creator of Audio Weaver, an embedded audio DSP development platform used across automotive and consumer audio. Highly comparable as a specialist embedded audio engineering platform and services provider.
• Linkplay Technology: Provider of audio streaming modules and firmware platforms (e.g., adopted by Audio Pro, Harman, IKEA) that ship into consumer audio products. Comparable as a one-stop embedded audio/smart-speaker platform provider serving the same OEM customer base.
• StreamUnlimited Engineering: Austria-based provider of audio streaming software platforms (StreamSDK) and modules. Closest peer to jusst as they share the same audio streaming platform ecosystem and serve overlapping audio OEM customers, though they are also a strategic partner.
• Arylic: Sells streaming amplifier boards and platforms (e.g., Up2Stream, A50) for OEMs and DIY audio brands. Direct peer in providing audio streaming hardware/software building blocks to audio brands.

Regional players

• XMOS VocalFusion ecosystem partners: Other boutique XMOS design firms (e.g., small UK/EU consultancies) that compete with jusst for the same XMOS-based VocalFusion and USB Audio design services engagements.

Broad incumbents

• Dirac Research: Sweden-based audio processing company behind Dirac Live room correction. Comparable as a premium audio technology partner to the same OEM customer base, though focused on software signal processing rather than embedded hardware design.
• NXP Semiconductors (Audio & Voice): Major silicon vendor offering audio DSP and voice processing ICs (e.g., i.MX RT, ULP). Comparable in the broader embedded audio technology stack, though at a much larger scale and with a semiconductor P&L model.

Emerging players

• miniDSP: Hong Kong-based provider of DSP audio platforms, processors, and embedded audio solutions for OEMs and pro audio. Comparable in the embedded audio/DSP space with a more productized, module-based offering.
• Volumio: Open-source audio player and streaming platform firm offering both software and OEM/embedded integrations for hi-fi brands. Comparable in the audio streaming platform niche with a more software-led, community-driven model.

Others

• XMOS: UK-based semiconductor and IP vendor whose xCore processors underpin much of jusst's firmware and VocalFusion work. A direct technology partner rather than competitor, but operates in the same embedded audio signal chain.
