How to Reduce a 60 Cycle Hum

Removing a hum below 60 cycles-per-second will help you improve the quality of your music and reduce unwanted noise. Audio filters make it possible to completely remove frequencies under a specified frequency range. You must use an audio editing program to accomplish the task of removing the hum. By applying a carefully constructed audio filter, you can isolate and remove the hum with ease. To effectively reduce the hum, you must use a high-pass filter that removes frequencies below the specified frequency which are measured in hertz, or cycles-per-second.
