The Sony ECM-B1M is an ultra-compact camera-mount digital shotgun microphone designed for mobile video creators working with Sony cameras equipped with the Multi Interface Shoe. Released alongside the a7R IV, which benefits from its built-in Digital Audio Interface, the ECM-B1M is able to produce its best quality by delivering a digital audio stream directly to the camera through the Multi Interface Shoe. Other Sony cameras with the standard Multi Interface Shoe can still make use of the microphone as there is a selectable digital/analog output.
The ECM-B1M is equipped with eight high-performance mic capsules and advanced digital signal processing, providing three selectable directivity patterns for a wide range of shooting and recording situations. Plug-and-play operation makes the microphone easy to use right out of the box—you can immediately start recording your YouTube videos, Facebook Live streams, and interviews, at home, in the studio, or on the go.

A low-cut filter that cuts out subsonic noise is implemented through digital signal processing, maximizing audio quality at the recording stage and thereby reducing the need for complex post processing.
A fur windscreen is supplied to help reduce wind noise when shooting outdoors.
