Audoo Limited is a UK music-technology company whose single registered IEEE MA-L block, 02:DD:6E, is assigned to "Audoo Limited" at Unit 23, Tileyard London, Tileyard Road, London N7 9AH, GB. The prefix appears in the IEEE MA-L registry only (decimal record 187758) and not in the smaller MA-M or MA-S spaces, so it is a full 24-bit OUI giving Audoo the standard ~16.7M-address block. The hardware behind this OUI is the Audoo Audio Meter, a small plug-in IoT sensor deployed in commercial venues such as shops, bars, gyms, restaurants, and stadiums. The device listens to ambient audio, builds an encrypted acoustic fingerprint on-device, and uploads only that fingerprint — never raw audio — to Audoo's cloud for music-rights reporting to PROs/CMOs like PRS for Music, PPL, and OneMusic NZ. Crucially for network classification, the Audio Meter connects over a built-in cellular SIM (2G/3G/4G) rather than venue Wi-Fi or Ethernet; it does not join the local network, so seeing this OUI on a LAN is unusual and the device presents essentially no LAN-facing attack surface. The prefix value 02:DD:6E itself has the locally-administered bit set in its first octet (0x02), an unusual trait for a globally-assigned OUI worth noting for anyone matching addresses. No public CVEs or security advisories were found for the device.
- IEEE assignment
- 02:DD:6E → Audoo Limited [Confirmed] — IEEE MA-L registry (enrichment/registries/oui.csv, decimal record 187758)
- Registry / block size
- MA-L (24-bit OUI; ~16.7M addresses per block) [Confirmed] — IEEE MA-L registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date; the maclookup.app "first seen" value (≈2021-05-22) is a third-party database artifact reflecting when that scraper first observed the entry, not an IEEE fact.
- HQ / registered address
- Unit 23 – Tileyard London, Tileyard Road, London N7 9AH, GB [Confirmed] — IEEE MA-L registry; corroborated as London, England (Covent Garden offices cited on company site) [Likely] — https://audoo.com/about/about-us, https://uk.linkedin.com/company/audoo
- Country
- United Kingdom [Confirmed] — IEEE MA-L registry, https://audoo.com/
- Company status
- active (funded UK music-tech startup) [Confirmed] — https://audoo.com/
- Device types
- Audoo Audio Meter — cellular-connected acoustic-fingerprinting IoT sensor for music-rights reporting in commercial venues. Not a switch, router, or general-purpose network appliance. [Confirmed] — https://audoo.com/resources/faqs, https://audoo.com/news/blog/audoo-system-architecture
- Connectivity
- built-in cellular SIM (2G/3G/4G) is the only outbound path; no Ethernet port or Wi-Fi radio documented; caches fingerprints locally and retries on poor signal. Does not require or join venue Wi-Fi/LAN. [Confirmed] — https://audoo.com/resources/faqs, https://audoo.com/news/blog/audoo-system-architecture
- Hardware detail
- PCB ≈10 cm × 4.5 cm with on-board microphones, UK-manufactured; firmware in Python/C/C++; on-device ML detects music and suppresses speech before fingerprinting; power draw below a USB phone charger. [Likely] — https://audoo.com/news/blog/audoo-system-architecture (single vendor source)
- Security context
- no known CVEs or public advisories; privacy-first design (raw audio never stored or transmitted, only an encrypted fingerprint leaves the device; no on-device speech processing); cellular-only model keeps it off the venue LAN. [Confirmed — null for CVEs; vendor-sourced for design] — https://audoo.com/resources/privacy-and-security, https://audoo.com/resources/faqs
- Notable context
- UK music-tech startup; investors reported to include Sir Elton John and Björn Ulvaeus; ranked in the UK MediaTech 50 (2024); deployed across multiple countries; works with PRS for Music, PPL, and OneMusic NZ; fingerprint library of 200M+ tracks.

- Address-format note
- 02:DD:6E has the locally-administered (U/L) bit set in octet 1 (0x02), atypical for a globally-administered OUI. [Confirmed] — 02 = binary 00000010, bit 1 set
- Analyst note
- This OUI reliably identifies an Audoo Audio Meter, but because the device is cellular-only it is rarely seen on a venue LAN; an unexpected appearance on a local network warrants investigation.
