how to not hear yourself in fl studio

Hello! This usually happens when your microphone has a 'monitoring' function enabled. What you'll want to do is to disable this feature. Can you let me know what kind of audio interface or hardware you're currently using with FL Studio?

Great. There's a 'Direct Monitor' switch on your Focusrite interface which controls whether you hear the direct input from your microphone or not. Make sure that this switch is turned off, this should stop you from hearing yourself.

Inside FL Studio, just ensure your current track isn't armed for recording. This is shown by a small red disk icon - it should be greyed out if it's not active. Try this and let me know how it goes.
