Sony’s ECM-AX10 connects to a smartphone to record sound from multiple directions. The small microphone aims to preserve a sense of distance and space beyond the frame.

Imagine filming a street performance. The performer looks clear on screen, yet the recording sounds different from standing there. If the instrument in front and the people beside you merge together, the sense of direction is diminished. A sharper picture alone cannot restore it.
The ECM-AX10, which Sony announced in Hong Kong on October 9, is a spatial audio microphone for smartphones targeting this gap. It connects via USB-C and records sounds from multiple directions with the four omnidirectional microphone capsules inside.
Beyond recording sound loudly
In spatial audio, it is important not only what sound is heard, but also where it appears to be coming from. This microphone offers three recording methods: Ambisonics, binaural, and regular stereo.
Ambisonics is a method used to produce spatial sound by recording the surrounding sound field. Binaural aims for a three-dimensional experience when listening through headphones. Stereo is an option suited to everyday video and listening environments. The same scene may call for different recording modes depending on where it will be published and how people will listen.
There are conditions even after filming
Connecting a microphone does not provide the same experience on all smartphones and playback devices. You must check the supported smartphone and operating system, and some shooting, editing, and export functions require the dedicated Spatial Audio Video Tool app.
Sony provides guidance on recording Ambisonics and posting to YouTube in Eclipsa Audio format using this app. The playback environment on the receiving end also has an impact. In the announcement material, 4K video recording was listed as planned for December 2026 or later, rather than as a currently available feature.
The point is not that one small plug perfects every recording. It gives the person filming a choice of how to capture sound, just as they choose what appears in the frame. Even if you film the same street performance, you have the opportunity to choose whether to leave only the performance clearly or convey the surrounding space as well.
