How can I stop my microphone from picking up desktop audio?

Another tip is to check the sound settings in your recording software. You might need to enable some sort of audio isolation or filtering option, which can help in preventing your mic from capturing desktop sounds. If all else fails, consider using a different microphone that offers better directional sound capture.

First, make sure to adjust your microphone settings in your audio control panel. You might need to lower the input volume or adjust the balance so it doesn't pick up external sounds. Also, try using a noise-canceling feature if your software has one. Sometimes, the positioning of the mic can also play a big part in this. If your mic is too close to the IEMs, it will definitely pick up what they're playing.
