Fix computer audio buzz noise

If you’ve ever heard a faint buzz, hiss, or hum coming from your computer audio output, this video explains why it happens and how to fix it without expensive gear. I show a simple, low-cost solution to eliminate background noise from your audio interface or any other USB-connected audio device. I’ll demonstrate how ground noise from your computer contaminates your audio system, and how to remove it safely using an audio isolation transformer or a USB ground loop isolator. You’ll learn why these issues occur, how to diagnose them, and which inexpensive tools can restore a clean noise-free signal.
