How to Remove Buzzing From Your Audio

 

Blurry shots and shaky videos aren’t the only problems videographers encounter in editing videos. Audio noise is a common dilemma due to noisy environments and cheap sound control equipment.


It’s a good thing you can remove the buzzing sound from the audio with the right editing equipment. But before we proceed to the technical process, let’s discuss the recording procedure.


Smooth Audio Recording

Having a buzzing or noisy audio sound is harmful to your audio. It can distract the viewers from understanding the video, thus, defeating its purpose to entertain, inform or educate. With this, you must do what you can to have smooth audio while recording.


So how do you achieve smooth audio? The best way is to record in a quiet environment. Next, use a functional microphone to record 10 to 20 seconds of the room tone. Listen to the recording to know what you can reduce for higher-quality raw audio. 


What can you hear in the recording? If you can hear the fan, simply turn it off while you record. Turn off any buzzing lights or ask people politely to give you a quiet time until the recording is over. If you’re only recording audio for a podcast or voice-over, you can simply put a thick blanket over your head to minimize outside noise.


Here are some more tips on how you can remove the buzzing:


  1. Use A Hum Eliminator

The most common cause of audio noise is the ground loop. It happens when one or more entertainment sets are plugged into multiple AC sockets and connected by signal cables whose shielding is connected to the ground. Some technicians may recommend using an extension cord, but that tends to be impractical; that’s why a hum eliminator is more favorable.


  1. Be Wary Of Your Wires

There are rules to wires and cables. The first is ensuring the power cable is far from audio or video signal cables. Meanwhile, the second one is to never loop antenna signal cables because of the electromagnetic induction. Choose the wires and cables suitable to your equipment to prevent inducing a buzzing noise.


  1. Invest In A USB Noise Filter

Believe it or not, USB and HDMI cables emit buzzing noises too. You can prevent interrupting your audio recording by having a USB noise filter that splits the shield connection. 


If all methods fail and you can still hear an annoying buzzing noise, it’s time to use the best audio software to create a smoother sound recording.
