I’m frustrated

Hum when recording with TTUSB

When recording there seems to be hum that comes out of nowhere and lasts for a second or two and then goes away. The hum actually records also but I know its not the record because it has a digital sound to it. The computer also seems to freeze during this hum and unfreezes after hum is done. Never experienced this before.

  • Hi Jeff,

    Thanks for posting. I'd like to help! Its most likely caused by a Ground Loop. In an electrical system, a ground loop is an unwanted current in a conductor connecting two points that are supposed to be at the same potential, often ground, but are actually at different potentials. Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems.
