What IDUN Audio does
IDUN Audio is a Danish spatial audio software company founded in 2018 that licenses embedded, edge-processing technology to headset manufacturers and chipset platform partners. The company's core product is a physics-based spatial audio engine that uses time-varying Head-Related Transfer Functions (HRTFs) and low-latency head tracking to reintroduce natural directional and distance cues to over-the-head headphones, earbuds, and smart glasses, addressing the 'sound inside the head' fatigue problem of conventional headphone listening. The technology is protected by US patent US2023-0403528 A1 (granted August 2025), supports up to 20 audio channels, and runs on the device rather than the playback source, enabling device-independent spatial rendering across iPhone, Android, PC, Mac, TV, and smart glasses.
IDUN serves four segments: consumer headsets and earbuds, enterprise and communication headsets, VR/AR/XR smart glasses, and dual-use/mission-critical applications in defense, aviation, and industrial environments. It monetizes through a B2B licensing model with three revenue streams: chipset platform licensing (integrated on Qualcomm S3/S5/S7, Airoha AB158x/159x, BES Technic 2700/2800, Synaptics Tahiti Lite, NXP RT600, Renesas, Sonical Remora, Bragi, and ARM M4/M33/M7), direct OEM/ODM licensing, and patent licensing. Distribution is amplified by an ODM partner network across China, Taiwan, India, and Singapore. Pricing is quote-based with multi-year contracts; no public tiers are disclosed.
The company is seed-stage with 1-10 employees, headquartered in Copenhagen with a London office. Existing investors include Accelerace Invest (lead), Midwich, IFD, Erhvervsfremme, EIFO, Eurostars, and the EU, with an active second seed round open in 2024. The leadership team combines 30+ years of spatial audio expertise at the CEO (Pauli Minnaar) with technical leads in signal processing, embedded software, acoustics, and system architecture, plus board members with 20-35 years in audio industry sales, hearing, and startup scaling. Notable recent moves include a November 2024 three-way partnership with InnoPhase IoT and GreenWaves for a lossless Wi-Fi audio reference design and the August 2025 US patent grant.

IDUN Audio product offering
Product offeringCore offering
IDUN Audio develops and licenses embedded spatial audio software that runs directly on headsets, earbuds, and smart glasses (edge processing). The software uses dynamic time-varying Head-Related Transfer Functions (HRTFs) to reintroduce natural spatial properties of sound—direction, distance, and acoustical environment—to over-the-head headphones, earbuds, and smart glasses. The platform is integrated on leading Bluetooth chipsets and audio platforms from Qualcomm, Synaptics, Airoha, BES Technic, NXP, Renesas, Sonical, Bragi, and ARM processors, and is licensed to headset manufacturers and consumer electronics brands globally.
Product overview
IDUN Audio offers a unified spatial audio software platform designed for deployment on edge devices (headsets, earbuds, and smart glasses). The core offering is the embedded spatial audio software that processes audio in real-time using dynamic HRTFs for natural spatial sound reproduction. The platform supports up to 20 audio channels through object-based real-time processing. Key modules include low-latency head tracking for precise spatial accuracy and a smartphone control application for customization. The software integrates with industry-standard Bluetooth chipsets and audio platforms from Qualcomm, Synaptics, Airoha, BES Technic, NXP, Renesas, Sonical, Bragi, and ARM processors, enabling deployment across consumer, enterprise, and mission-critical applications. The company also provides reference designs combining their spatial audio software with Wi-Fi and AI processors from partners InnoPhase IoT and GreenWaves.

IDUN Audio competitors and assessment
Company assessmentDirect peers
- Waves Audio: Audio DSP company with a long-standing licensing business across consumer, professional, and gaming audio — including spatial and headphone-processing IP. Comparable B2B audio middleware licensor with deep chipset and OEM footprint.
- Dirac Research: Swedish B2B audio processing company that licenses spatial audio, headphone virtualization, and sound optimization software to OEMs across headphones, automotive, and mobile. Closest direct analogue to IDUN in business model (chipset/OEM licensing) and category (spatial audio for headphones).
- Mimi Hearing Technologies: Berlin-based audio personalization company licensing personalized sound and hearing-based audio processing to headphone/earbud OEMs and chip partners. Comparable B2B model targeting the same hearables market with embedded audio enhancement IP.
- Sonarworks: Latvian audio software company providing sound personalization and spatial audio calibration, B2B-licensed to headphone manufacturers and music creators. Comparable as a software-only spatial/personalization player targeting the same OEM licensing motion.
- THX Ltd. Audio technology company licensing spatial audio and headphone tuning IP to OEMs and consumer electronics brands, with similar deployment in headsets and earbuds. Comparable as a B2B spatial audio licensor chasing tier-1 headphone brands.
Emerging players
- Embody: Emerging spatial audio company focused on immersive sound for gaming headsets and VR/AR. Overlaps with IDUN's VR/AR/XR and gaming endpoints, though narrower in vertical focus.
- Sonical: Emerging hearables platform company building an operating-system layer for smart earbuds on Renesas silicon; listed as IDUN integration partner but also adjacent competitor in the hearable software stack.
Broad incumbents
- Dolby Laboratories: Dominant spatial audio incumbent via Dolby Atmos for Headphones, licensing to OEMs, streaming services, and device makers globally. Represents the bundled-competitor risk to IDUN's B2B licensing motion in consumer headsets.
- Sony (360 Reality Audio): Sony's 360 Reality Audio initiative delivers spatial audio across Sony's own headphone lineup and partner streaming services. Comparable incumbent pushing spatial audio through a vertically integrated consumer electronics stack.
- Apple (Spatial Audio): Apple Spatial Audio ships across AirPods and Beats, bundled with iOS/macOS. Largest platform-controlled incumbent, illustrating how consumer-reach bundling can pressure third-party spatial audio licensors.
