Dehumming for Ringtones

50/60Hz humming (and its harmonics) caused by power supplies, guitars/amps, or just bad cable connections will be removed.

One major cause of humming derives from the fact that audio wiring is very susceptible to "ground loops." This can occur, for example, when two pieces of audio equipment are plugged into different power outlets that have a difference in their respective "ground potentials." The result is that if a signal flows from one piece to the other via an unbalanced connection, this potential difference causes a spurious current, in turn creating an audible "hum" at the AC frequency (50 or 60 Hz) and its harmonics (100/120 Hz, 200/240 Hz, etc). We test every ring tone.
