Extinct Audio is a UK-based manufacturer of handcrafted ribbon microphones, founded by Stewart Tavener alongside collaborators Adam Watson and Ant. Tavener had previously built a reputation through Xaudia, a ribbon microphone repair service that serviced thousands of vintage mics. The brand's name references the near-disappearance of ribbon microphones from mainstream production, a gap Extinct Audio set out to fill with affordable, hand-assembled alternatives.

The company's catalog centers on ribbon designs with figure-of-eight polar patterns. Models include the BM9 "Viking," a general-purpose studio ribbon; the Black Ops, a ruggedised variant with a thicker 2.5-micron ribbon aimed at high-SPL sources like guitar cabinets; the Valkyr stereo ribbon; the compact BoRbon pocket ribbon; and the BerZerker. Transformers are wound in-house and microphones are assembled at the company's UK facility, with components sourced from nearby suppliers.

Extinct Audio has been covered in Sound on Sound and stocked by specialist dealers such as Funky Junk and Vintage King, positioning it within the boutique end of the ribbon microphone market alongside makers focused on studio recording applications.

Extinct Audio has 2 products cataloged on Equipboard, including Ribbon Microphones.
