3PCS INMP441 Omnidirectional Microphone Module I2S Interface MEMS High Precision Low Power Ultra Support ESP32

The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface.
The INMP441 has a high signal-to-noise ratio and is an excellent choice for near field applications. The INMP441 has a flat wideband frequency response that results in high definition of natural sound.
The I2S interface allows the INMP441 to be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system. 4.Interface definition: SCK: Serial data clock for I2S interface; WS: Serial data word selection for I2S interface; L/R: Left/Right channel selection.

Omnidirectional microphones are highly sensitive, and pickup radius is too large, and it will also pick up more ambient noise, so the sound quality is not as good as the single-point microphone, unless you do a good noise reduction. There is definitely a difference between collective use and single-person service.But omnidirectional wheat has a benefit, the wiring is simple, not one by one. Suitable for small meetings, ad hoc meetings, some remote discussions, remote operations.
