Here are the ways to prevent noise when recording a podcast with two Rode NT-USB microphones in one room:
Use software: You can use software solutions that offer a real-time noise gate that should take effect system-wide. You can also use OBS to set a noise gate filter.
Adjust the settings in communication applications: In applications such as Teamspeak or Discord, you can set the audio setup so that the microphone is only activated above a certain volume threshold.
Use post-production: You can also filter out the noise in post-production.
Pay attention to correct placement and distance: The placement and distance of the microphone can also have an influence on the noise. Make sure the microphone is at an appropriate distance from you and away from other sounds.
Use push-to-talk: Another option is to use push-to-talk. This will only activate the microphone when you want to speak.
