Can you Eq out background noise?

An Equalizer (EQ) lets you control the volume of specific frequencies or ranges of frequencies in sound. If your background noise is at a particular frequency, like a constant hum or hiss may be, then you can use the EQ to lower the volume of that particular frequency and hopefully eliminate the sound altogether.

Can VLC remove background noise?

Navigate to the bottom right corner, where you'll find the Audio Effects icon. Once you're in the Audio Effects folder, select Equalizer. This will allow you to begin the process of deleting or muting each unwanted sound manually, one band at a time.
