Compact four-capsule USB-C spatial audio microphone attached to a smartphone recording live music

Sony is bringing spatial-audio recording directly to smartphones with the new ECM-AX10, a 24-gram USB-C microphone built around four omnidirectional capsules.

In its October 8 announcement, Sony says the ECM-AX10 is the world’s first smartphone microphone certified for Eclipsa Audio. The official Eclipsa Media program now lists Sony’s microphone in its October 2026 updates, supporting the certification claim.

Field-recording users discuss the ECM-AX10’s four-capsule design, price and early appeal.

The microphone records in three modes: Ambisonics for spatial production, binaural audio for headphones and conventional stereo. Sony’s companion app can record, review, edit and export spatial-audio video on the phone. Compatible devices need iOS 18 or Android 14 or newer plus USB-C.

Eclipsa matters because it is based on the open IAMF format and can be published to YouTube. BitcoinVersus.Tech has also tracked YouTube’s expanding creator tools and Sony’s broader next-generation media technology work.
