Try using a directional or cardioid microphone because they only pick up sounds from what they’re pointed at. Avoid using an omnidirectional microphone if you can since it captures audio from every angle and is prone to feedback.
Opt for direct input for instruments if you can so you don’t need to hook them up to a microphone first.
Many recording microphones have a port that you can plug headphones into directly so you can hear your own audio as well.
If there isn’t a switch or button on the microphone, then you may need to unplug the cable attached to it instead.
Avoid pointing speakers at walls, ceilings, or windows since they’ll make sounds bounce even more. Instead, point the speakers toward people or a crowd.
You can find the gain control either on the audio mixer or the digital audio workstation you’re using. Some microphones also have a gain control knob on them so you can adjust the microphone before it goes into a sound system.
Be careful not to turn the speakers down too much, or else you may not be able to hear the audio clearly. Only turning down the speakers may not completely reduce feedback. You may need to use additional methods to completely eliminate it.
As you get used to how the feedback sounds, you may be able to detect which frequencies are causing problems by ear.
You can buy automatic feedback eliminators from audio supply stores or online. Automatic feedback eliminators work best for live performances or presentations.
Most digital audio workstations have noise gate plug-ins already installed. Avoid setting the filter too high since it may cut off whatever you’ve recorded.
