You have a series of 0 and 1 bits, each taking a particular amount of time on the cable.

Anything besides thicker wires will be pointless.ĭata going through USB is DIGITAL, not analogue. Those ferrite beads will do nothing for the quality of the data going through the usb cable. I think I'm going to order a clip-on ferrite noise suppressor if I encounter noise issue with my new USB audio interface. I’ve never used one, because the first and second methods are far cheaper and have never failed me. These cost around $50 and are said to indeed eliminate the noise. The third method is to get a USB noise filter (I’ve never seen one for HDMI, but an HDMI adapter could work), which is actually a USB re-transmitter that splits the shield connection. This is also known as a ground shunt, or simply a shunt.

Electricity always follows the path of least resistance, so spurious current runs down the ground wire rather than the cable’s shield. The second method is to run a wire that’s less resistive than the USB/HDMI cable shielding from the case of the USB audio interface or HDMI-connected audio component to the case of your computer. These are sometimes called a ferrite bead. You can also buy a clip-on ferrite noise suppressor). One is to use a cable with a ferrite noise suppressor sleeve (that big round slug at one end. There are three methods for removing USB (and HDMI) cable noise.
