. Sony introduces the ECM-B1M Digital Shotgun Microphone for interchangeable lens cameras. . Advanced digital signal processing makes it possible to offer three switchable directivity patterns in one versatile microphone: super-directional, unidirectional, and omnidirectional. Eight high-performance microphone units work with a newly developed beamforming algorithm to provide extremely sharp directivity that effectively rejects off-axis sound. All of this is achieved in a remarkably compact microphone that is only 99. 3mm in length. . A low-cut filter that cuts out subsonic noise is also implemented through digital signal processing, maximising audio quality at the recording stage and thereby reducing the need for complex post processing. . No need for extra cables or batteries! Simply clip the microphone into the Multi Interface Shoe on a compatible camera for direct power and audio connections. . The ECM-B1M is supplied with a fur type wind screen that can reduce wind noise when shooting outdoors.
