Dayton Audio iMM-6C USB-C Measurement microphone

Turn any phone or tablet with a USB-C connector into a high-quality audio measurement device with the Dayton Audio iMM-6C USB-C measurement microphone. Each iMM-6C is individually hand-calibrated using a laboratory microphone for consistent, repeatable measurements that match the level of accuracy previously offered only by much more expensive stand-alone microphones.

Dayton Audio iMM-6C: Omnidirectional microphone capsule

The omnidirectional pick-up pattern of the Dayton Audio iMM-6C microphone offers a wide range of advantages and possibilities. Using an omnidirectional electret condenser capsule, this microphone is designed to pick up sound equally in all directions. Whether you're assessing the acoustics of a concert hall, recording studio or dedicated home theater, this microphone can accurately capture the spatial characteristics and reverberation of the space. When it comes to measuring the output of a loudspeaker, an omnidirectional microphone captures the sound emitted from all angles. This gives you a complete representation of the loudspeaker's performance, enabling you to analyze its frequency response, distortion levels and other important characteristics.
