About Hum & Buzzing
Electrical hum is that annoying constant tone caused by power line interference, ground loops, or badly shielded cables. It is a common issue worldwide and often comes with additional buzzing overtones. This tool identifies those unwanted tones and removes them without messing with the natural sound of your voice.
Tips for Better Results
- Use balanced (XLR) cables instead of unbalanced connections to cut down on electromagnetic interference.
- Keep audio cables away from power cables and transformers.
- A power conditioner or ground loop isolator can kill hum at the source.
- If you are recording on a laptop, try running on battery power to avoid ground loop issues.
