After hearing many complaints about 60 hertz related hum, I decided I should solve the problem. This is the first of many signal processing programs I hope to offer here at GhostGadgets.com.

HumFilter v1.0
HumFilter is a notch filter program that works with any 16 bit WAVE file. You have the option of selecting 50 or 60 hertz as the frequency to get rid of, or you can enter your own custom frequency. The program will then "notch" (zero) that frequency as well as a user-selected number of harmonics of that frequency. HumFilter is SHAREWARE and is available for Windows and MacOS X.

Download HumFilter for Windows

These programs are SHAREWARE! If you found these programs helpful, please send a donation via paypal to info@GhostGadgets.com. There isn't a minimum or maximum value to send, just whatever you feel the programs are worth to you. Many hours went into writing this software, and the only way future updates and other programs can be made available is by your support.
