SUGGEST HIGH GAIN MICROPHONE

[aqildad-create]

i want to pick a sound from around 2 feet .

i use INMP441 and volume.setVolume(60 ) then its working but it add lot noise due to high volume increase .

so please suggest a microphone which have a pick up of around 2 feet.

There are no microphones with certain pick up distances, only sensitivity is a parameter.
I guess that you want to record a soft sound? the INMP441 mics are quite low noise inherently so this should be fine. Can you check if normal speech/sounds are recorded well? Maybe a wrong I2S setting, or you used the wrong channel (and did you solder the W/S signal to the specified channel?) . For very low noise, you can add a small capacitor across the power supply pins of the microphone (100nF is already ok for removing chirping sounds)

thanks for msg and reply .

i google soft sound but i am still confuse about soft sound.

i am recording the normal speech . with near to microphone the recorded is very good and no noise .

But with around 2 feet from microphone the speaker volume is very low so i have to set the volume to around 60 but when when i set to 60 i can clearly listening high noise with speech .

i need a sound pick from 1 to 2 feet .

i use default i/o pins use in the API.
PIN_I2S_BCK = 14
PIN_I2S_WS = 15
PIN_I2S_DATA_IN = 32

You can see from the board schematic on board 100n capacitor is already place .
