Hi @taekonv55 ,
Thank you for posting your question.
3Dio microphones contain two omnidirectional capsules in each ear. Omnidirectional microphones capture sound in all directions, just like our own ears do. In other words, if you can hear a sound in the room you're recording in, then the 3Dio mic will also hear it. The microphones are designed to mimic human hearing.
You can use a 'denoise' effect in your recording/streaming software to reduce white noise sounds, but the best way to reduce extraneous noise is to simply remove the noise from the recording space. It also helps to use soundproofing material in the room to get a quiet space.
I hope this information helps. Please let us know if you have any additional questions.
